Description

  The present invention relates to an identity identification system, an identity identification method, and a method for attaching an identification information recording apparatus used in the system and method.

  Identification of an unidentified person in a large-scale disaster is easy if the person is conscious or if the unidentified person has something that can identify himself such as a driver's license. In the case of, in the event of an emergency such as a large-scale disaster, you do not have something that can identify you. Under the present circumstances, in such a case, a dentist often identifies himself / herself from a tooth arrangement, a treatment mark of a tooth, and the like. However, it takes a lot of time for the actual identification work, and the identity cannot be identified unless a dental chart in the unidentified person's dentist is found.

  In addition, as an identification method, there are methods such as DNA identification and fingerprint verification. However, when many unidentified people appear at a time, such as during a large-scale disaster, DNA analysis requires a lot of time and money. In addition, fingerprints may be difficult to collect depending on the situation at the time of disaster or the passage of time, and the verification work is limited in the first place.

  Furthermore, not only at the time of a large-scale disaster, for example, when a patient with dementia goes missing or is involved in an incident or accident, the patient suffering from serious illness is unconscious or difficult to talk on the go. In case of so-called lonely death such as elderly living alone, traffic accidents, drowning accidents, mountain accidents, etc., or when the person himself is unconscious due to an incident etc. May be required. In particular, in recent years, about 1 in 4 people in Japan are facing a super-aging society where they are over 65 years old, and it is expected that the situation that requires identification will increase more and more. Therefore, there has been a demand for a method that can more easily identify an unidentified person.

  Here, a medium in which information such as a non-contact type IC chip (also referred to as “IC tag”, for example, an RFID (Radio Frequency IDentification) tag) can be recorded in advance on a prosthesis or the like in the subject's oral cavity. A system or method is proposed in which the subject's biological information or personal information is read from the medium embedded in the prosthesis or the like, and the read information about the subject is used (for example, Patent Documents 1 to 3). 4).

Japanese Patent No. 4986382 JP 2013-97440 A JP2013-109745A JP 2004-195143 A

  The techniques described in Patent Documents 1 to 4 are basically techniques (chip embedded type) on the premise that a non-contact type IC chip is embedded in a prosthesis or a restoration. In such a chip-embedded type, once the IC chip is installed in the oral cavity, if the IC chip is no longer needed, the restoration is repacked, and the prosthesis is remanufactured or repaired (shaved to remove the IC chip). It is necessary to fill the shaved part again after removing the material, which is extremely difficult. In addition, when an IC chip is embedded in natural teeth, the sound tooth is originally cut and embedded, so if the IC chip is no longer necessary, it must be returned to its original state before it is cut (original state). This is impossible, and the shaved part needs a new repair procedure. As described above, the chip-embedded methods described in Patent Documents 1 to 4 are irreversible, once an IC chip is installed, it cannot be restored to its original state when it becomes unnecessary. It can be said that it is a technique.

  In the case of the above-described chip embedded type, the timing for installing the IC chip is as follows: when a prosthesis is manufactured (when the prosthesis is manufactured, the IC chip is built in), during tooth treatment (the caries portion is After the removal, it can be further sharpened and an IC chip is embedded in the defective portion). On the other hand, when tooth treatment is not particularly necessary, it is very difficult to embed an IC chip in a prosthesis or restoration, including a healthy portion of a natural tooth, which is not practical. As described above, the chip-embedded method has a limited timing for installing the IC chip.

  Furthermore, there is the “8020 Movement” that started as a business of the Ministry of Health, Labor and Welfare (the Ministry of Health and Welfare at that time) and the Japan Dental Association since 1989. This exercise is aimed at over 20 years of age, with 20 or more teeth remaining (usually, the total number of human teeth is 28, except for wisdom teeth). At the start of the “8020 Movement”, the percentage of people over 80 years old who had 20 or more teeth (achieved) was only about 7%. Exceeded 38%. In other words, there are at least one in three people who are over 80 and have 20 or more teeth left. In this way, many elderly people including many remaining teeth do not have a prosthesis at the position where the IC chip is to be installed (not only when there is no prosthesis in the oral cavity, (Including the case where the tip is placed at a healthy tooth and the prosthesis is present at other sites.) In such a case, since the techniques of Patent Documents 1 to 3 are intended to embed an IC chip in a prosthesis in the first place, it is not possible to install an IC chip on natural teeth. The position may be limited.

  On the other hand, in the technique of Patent Document 4, natural teeth (tooth) other than prosthetics and restorations are also targeted. However, since Patent Document 4 has a description that "when an IC chip is provided on a crown or the like, a tooth (natural tooth) can be mounted without damaging it", the technique described in Patent Document 4 is targeted. When an IC chip is placed on a healthy tooth, an invasive action on a natural tooth is required, such as cutting and damaging a healthy tooth or damaging a tooth nerve. Moreover, since the techniques of Patent Documents 1 to 3 are originally chip-embedded techniques, an invasive action on the prosthesis is required.

  Therefore, the present invention has been made in view of the above circumstances, and identification information for an unidentified person is recorded in an identification system for identifying the identity of an unidentified person and an identification method using the system. When the identification information recording apparatus (for example, IC chip) is installed in the oral cavity of the user of the system, it is intended to be implemented by a non-invasive method. Moreover, even if it becomes unnecessary after the installation of the identification information recording device, it is a reversible method capable of returning a restoration or prosthesis to a state before installation, including a healthy tooth, An object of the present invention is to make it possible to freely select the installation timing and the installation position of the identification information recording apparatus in the above system and method.

  As a result of intensive studies to solve the above problems, the present inventor has identified an identification information recording apparatus in the identity identifying system for identifying the identity of an unidentified person and the identity identifying method using the system. Reversible by applying a dental material to the healthy part of a natural tooth, restoration or prosthesis of a system user (identified at the time of identification) In addition, the identification information recording apparatus can be installed by a non-invasive method, and the installation timing and installation position can be freely selected, and the present invention has been completed based on this finding.

That is, the present invention is a method of applying an identification information recording device used in an identification system for identifying the identity of an unidentified person, wherein the identification system is a natural tooth of a user of the identification system Identification information that is affixed with a dental material on the lip side surface of the anterior tooth part or the buccal side surface of the premolar part in a healthy part, restoration or prosthesis, and in which identification information for identifying the user is recorded A recording device; an identification information reading device that reads out the identification information from the identification information recording device by directivity wireless communication; identity identification information for identifying the identity of an individual to whom the identification information is assigned; and the identification An identification information database associated with information, and capable of acquiring the identification information read by the identification information reading device, Is configured to check the obtained identification information of the user against the identity information database and extract the identification information associated with the identification information of the user when the identification information is acquired. The application method of the identification information recording apparatus comprises: an application step of applying a fluid dental material to a healthy part of the user's natural teeth, an outer surface of a restoration or a prosthesis; and the application An adhesion step for adhering the identification information recording device to the adhered dental material, and the surface and the entire periphery of the bonded identification information recording device in the shape of the surface of the surrounding natural tooth, restoration or prosthesis A coating step for coating so as to be coated with a dental material having the same fluidity as the dental material used in the coating step, and the coating step and the coating step. Characterized in that it comprises a curing step of curing the dental material flowable that cloth, a sticking method of the identification information recording apparatus.

  According to the present invention, in an identity identifying system for identifying the identity of an unidentified person and an identity identifying method using the system, an identification information recording device is used for the natural tooth of a user (unidentified person) of the system. By sticking to the outer surface of a healthy part, restoration or prosthesis with dental material, the identification information recording device can be installed in a reversible and non-invasive manner, and the installation timing and installation position can be freely set Selectable. Further, according to the present invention, the installation method of the identification information recording apparatus is not a chip embedded type as in the past, but is simply affixed by a dental material such as a dental adhesive (chip affixing type). The installation of the identification information recording apparatus becomes much easier than before.

<System configuration>
As shown in FIG. 1, an identity identification system 100 according to this embodiment is a system for identifying the identity of an unidentified person, and includes an identification information recording device 110, an identification information reading device 120, and an identity identification device 130. And an external connection terminal 140. In this identification system 100, as will be described in detail later, identification information for identifying an unidentified person recorded in the identification information recording device 110 is read by the identification information reading device 120, and the identification device 130 identifies the identification information. Based on the identification information read by the information reading device 120, the identity of the unidentified person is identified from the identification information for identifying the identity of the person associated with the identification information. Situations that require identification are not particularly limited.For example, not only during a large-scale disaster, but also when a patient with dementia is missing or is involved in an incident or accident during a drought, suffers from serious illness. When a patient is unconscious or has difficulty in talking on the go, in the case of so-called lonely death such as an elderly person living alone, in the case of an accident such as a traffic accident, a drowning accident, a mountain accident, etc. This includes all cases where the identity of an unidentified person is required, such as when the person is unconscious.

  The identification information recording apparatus 110 and the identification information reading apparatus 120 can communicate with each other by radio waves or electromagnetic waves 11 or the like. In this embodiment, the identification information reading device 120 can communicate with the identification device 130 via the Internet 13 and can be connected to the external connection terminal 140 via a wired or wireless LAN 15 or the like. Further, as will be described later, the identification information reading device 120 includes an output device such as a display panel or a speaker (output device 120e in FIG. 2), and outputs the identification information via this output device.

For example, the communication between the mobile phone 150 of the reader 151 and the mobile phone 160 of the input person 161 is not limited. Any communication means capable of transmitting identification information between the reader 151 and the input person 161 such as a call 19 can be used.

  Next, the form and specific example of each device will be described.

[Identification information recording device 110]
The identification information recording device 110 is a healthy natural tooth of an unidentified person (a person who desires to attach the identification information recording device 110 to his / her teeth before becoming unidentified = a user of the identification system 100). It is a device in which identification information for identifying an unidentified person is recorded, which is affixed to the outer surface of a correct part, restoration or prosthesis with a dental material including at least a dental adhesive.

  The identification information recording device 110 is a device capable of non-contact communication (wireless communication) at a relatively short distance (for example, several centimeters) with the identification information reading device 120. Specifically, as the identification information recording device 110, for example, an RF tag or the like in RFID (Radio Frequency Identification) can be used, as long as it has a function of the identification information recording device 110 described later. It is not limited to.

(RF tag shape)
Examples of the shape of the RF tag include a coin type, a cylindrical type, a label type, a card type, and the like, but are described as users of the identification system 100 (hereinafter simply referred to as “users”. It has a size that can be applied to a healthy part of a natural tooth, a restoration or a prosthesis (hereinafter sometimes referred to as “natural tooth, etc.”). If so, the shape is not particularly limited.

(RF tag types)
In addition, RF tags include passive tags that operate as an energy source by converting radio waves or electromagnetic waves from a reader / writer into electric power, active tags that operate with a built-in power supply (spontaneously transmit radio waves), and higher systems. There is a semi-active tag that activates the communication in a passive manner. Here, since the identification information recording apparatus 110 according to the present embodiment is affixed to a user's natural tooth or the like, it needs to be small enough to be affixed to the natural tooth or the like. On the other hand, since the active tag and the semi-active tag with a built-in power source become large and difficult to be attached to a user's natural tooth or the like, the identification information recording apparatus 110 according to this embodiment includes a power source. Passive tags that do not need to have a built-in are suitable. In addition, by using a passive tag as the identification information recording device 110, the identification information recording device 110 is not turned on during normal times, but is turned on only when reading the identification information. There is no adverse effect on the user to whom the recording device 110 is attached.

  In the case of a passive tag, in order to activate an IC chip, radio waves or electromagnetic waves from a reader / writer are required, so an antenna is required. However, if the antenna is configured separately from the IC chip, the user It is necessary to further connect an antenna to the IC chip affixed to the natural tooth. Here, for example, when an unidentified person cannot open his / her mouth for reasons such as unconsciousness, it is extremely difficult to connect an antenna to an IC chip affixed to the unidentified person's natural teeth. Difficult and unrealistic. Therefore, in the identification information recording apparatus 110 according to this embodiment, the RF tag processes a film-like inlet in which an IC chip on which identification information is recorded and an antenna connected to the IC chip are sealed with cellophane or the like. It is preferable that As such an inlet, for example, as shown in FIG. 1, there is one in which an IC chip 110b is connected to the tip of a spiral antenna 110a.

(RF tag communication method)
When an RF tag is used as the identification information recording apparatus 110 according to the present embodiment, if the communication distance with the reader / writer used as the identification information reading apparatus 120 is too short, the identification information recording apparatus 110 affixed to the natural tooth or the like of an unidentified person. It becomes difficult to read the identification information from. On the other hand, if the communication distance is too long (for example, several tens of centimeters to several meters), for example, the identification information in the identification information recording apparatus 110 is read without knowing from a place away from a third party having a reader / writer. There is a problem from the viewpoint of security, such as being feared. Therefore, it is preferable that the communication distance between the identification information recording apparatus 110 and the identification information reading apparatus 120 according to this embodiment is about 1 to several cm.

  Here, RFID communication methods include an electromagnetic induction method (method using electromagnetic waves) and a radio wave method (method using radio waves). The frequency band used in the electromagnetic induction method includes 135 kHz and 13.56 MHz, and the frequency band used in the radio wave method includes a 900 MHz band and a 2.45 GHz band.

  Among the frequency bands used in the electromagnetic induction method, the frequency band of 13.5 kHz has a long wavelength and is generally used in applications that require portability because the antenna is enlarged to generate electromagnetic waves by electromagnetic induction. Not. The 13.56 MHz frequency band (HF band) is used for Felica (registered trademark) and the like, and the communication distance is originally short. Therefore, when the RF tag is reduced to such an extent that it can be applied to the natural teeth of an unidentified person, the antenna is also reduced accordingly, so the communication distance becomes very short (for example, about several millimeters), and the unidentified person It becomes difficult to read the identification information from the identification information recording device 110 attached to the natural tooth or the like.

  On the other hand, the 900 MHz band (UHF band) and 2.45 GHz band (microwave band), which are frequency bands used in the radio wave system, can achieve a certain communication distance and can be applied to natural teeth of unidentified persons. Even if the RF tag is downsized, a communication distance of a certain degree (about 1 to several centimeters) can be realized. Therefore, it is preferable that the RF tag used as the identification information recording device 110 is a communication method using radio waves in the UHF band or the microwave band. In addition, when using the UHF band or the microwave band, the communication is directional, and the communication area can be relatively easily limited. Therefore, the identification information recording device 110 attached to the natural teeth or the like of an unidentified person. It is suitable as an application for reading identification information from.

  Note that the radio waves in the UHF band can be expected to wrap around because the wavelength is close to the size of an article around us. Therefore, communication is possible even if there are some obstacles. Therefore, for example, when the identification information recording apparatus 100 is used for an application in which there are many obstacles around a large-scale disaster or the like, it is preferable to use an RF tag that uses radio waves in the UHF band. It is believed that there is. On the other hand, since the microwave band radio wave has a short wavelength, wraparound is unlikely to occur, and the communication distance cannot be increased as compared with the 900 MHz band radio wave. However, since the radio waves in the microwave band are not easily affected by metal and the antenna can be easily miniaturized, for example, when the identification information recording apparatus 100 is used in a place that is easily affected by metal, the microwave band It is considered to be preferable to use an RF tag using the radio wave.

  Examples of commercially available RF tags suitable as the identification information recording apparatus 100 as described above include UHF ultra-small package tags (manufactured by Hitachi Chemical Co., Ltd.).

[Identification information reading device 120]
The identification information reading device 120 is a device that reads identification information from the identification information recording device 110 by wireless communication. This identification information reading device 120 is a device capable of non-contact communication (wireless communication) at a relatively short distance (for example, several centimeters) with the identification information recording device 110. Specifically, as the identification information reading device 120, for example, a reader / writer in RFID (Radio Frequency Identification) or the like (in this embodiment, it is sufficient if it has at least a function as a “reader”, and is not necessarily a “writer”. However, the present invention is not limited to this as long as it has the function of the identification information reading device 120 described later.

  The reader / writer mainly includes a handy type, a stationary type, and a gate type. Of these, for example, when identifying a large number of unidentified people at the time of a large-scale disaster, etc., when performing identification while moving, etc., it is necessary to use a hand-held type with a built-in antenna and excellent portability Is preferred. In addition, for example, when the identity of a patient with dementia in the cage is identified with a police box or the like, when the identity is identified at a fixed location, a stationary type or a gate type may be used. . In general, the handy type has a low output and a relatively short communication distance with the RF tag. However, when used in the identification system 100 according to this embodiment, the communication distance may be relatively short.

[Identification Device 130]
The identification device 130 includes an identification information database in which identification information for identifying the identity of an individual to whom identification information is assigned is associated with identification information, and the identification information read by the identification information reading device 120. It is a device that can acquire. The identity identifying device 130 has a role as a server device that records and manages an identity information database in the identity identifying system 100. As will be described in detail later, the identification information reading device 120 also has a role of identifying the identity of an unidentified person by collating the identification information read with the identity information database.

[External connection terminal 140]
The external connection terminal 140 is a terminal that can communicate with the identification information reading device 120 mainly at a spot where an unidentified person is found, and since it is also assumed to be used outdoors, a portable terminal ( For example, a laptop PC, a tablet PC, a smartphone, or the like is preferable. The external connection terminal 140 is not necessarily required in the present embodiment, but by using the external connection terminal 140, the external connection terminal 140 can be used even when the identification information reading device 120 does not have an output device. The identification information can be recognized (specified) by a display device such as a display. Further, if the external connection terminal 140 is in a state where it can communicate with the identification device 130 via the Internet 13 or the wired or wireless LAN 17, the identification information reading device 120 is in a state where it cannot connect to the Internet 13 (or connected to the Internet 13). Even if the mobile phone 150 and the mobile phone 160 cannot communicate with each other, the identification information acquired via the external connection terminal 140 is identified. Transmission to the specific device 130 is possible.

<Hardware configuration>
Next, the hardware configuration of the identification information recording device 110, the identification information reading device 120, and the identity identification device 130, which are main components in the identification system 100 according to the present embodiment, will be described with reference to FIGS.

  The IC chip 110b is electrically connected to the antenna 110a. When the antenna 110a receives the radio wave or electromagnetic wave 11 transmitted from the identification information reading device 120, the IC chip 110b is activated by the power supplied from the antenna 110a. The IC chip 110b mainly includes a CPU (Central Processing Unit) 110c and a storage device 110d.

  The CPU 110c functions as an arithmetic processing device and a control device, and controls the operation of the identification information recording device 110 (for example, the operation of each device of the antenna 110a and the storage device 110d) according to various programs recorded in the storage device 110d.

  The storage device 110d stores data such as programs, calculation parameters, and identification information used by the CPU 110c. The storage device 110d may be either a read-only ROM (Read Only Memory) or a writable RAM (Random Access Memory). However, in the identification information recording device 110 in the identification system 100 according to the present embodiment, the identification information should be a single piece of information unique to the unidentified person to which the identification information recording device 110 is affixed. Since no other information should be written, it is preferable to use a ROM as the storage device 110d. ROM includes mask ROM, EPROM, EEPROM, etc. Among these, it is particularly preferable to use a non-rewritable mask ROM so that identification information is not rewritten unnecessarily.

The storage device 120f includes, for example, a magnetic storage device such as an HDD (Hard Disk Drive), a semiconductor storage device such as a RAM or a ROM, an optical storage device, or a magneto-optical storage device, or a combination thereof. The identification information reading device 120 does not need to store the identification information constantly, and it is sufficient to store the identification information temporarily until it is provided to the identification device 130 or the external connection terminal 140. The storage device 120f may be only a device capable of primary storage such as a RAM.

  Although not shown, the identification information reading device 120 may include an input device such as a touch panel, buttons, switches, and levers.

[Identification Device 130]
As illustrated in FIG. 6, the identification device 130 includes a storage unit 131, a communication unit 132, an input unit 133, an identification information acquisition unit 134, an identification information recording unit 135, a collation unit 136, and identity information output. A unit 137 and a database (DB) update unit 138 are mainly provided. As will be described in detail below, when the identification information is acquired, the identification device 130 checks the acquired identification information of the unidentified person against the identification information database, and is associated with the identification information of the unidentified person. Extract identification information.

(Storage unit 131)
The storage unit 131 is a function realized by the CPU 130a and the storage device 130b described above, and is recorded in the identification information recording device 110, in other words, a user to whom the identification information recording device 110 is attached (in other words, an unidentified person). An identification information database (DB) in which identification information for identifying the identity of an individual to whom identification information is assigned and identification information is associated is stored. The identification information is not particularly limited as long as it is information that can identify the identity of the user (unidentified person). For example, the name, address, and emergency of the user (unidentified person) Contact information (telephone number, e-mail address, etc.) that can sometimes be contacted, date of birth, work name, work address, work phone number, license number, passport number, family structure, etc. However, from the viewpoint of protecting personal information and reducing the psychological burden on the user, the identification information is the minimum information (for example, name, address, emergency) to identify the identity of the user (unidentified person) It is preferable that only the contact information of time etc.).

  Here, the configuration of the identity information DB will be described with reference to FIG. As shown in FIG. 7, in the identity information DB, an ID number is registered as an example of identification information, and the name, address, and contact telephone number of a user (unidentified person) are registered as an example of identification information. . In the example shown in FIG. 7, a combination of a single alphabetic digit and a three-digit number is illustrated as an ID number, and each ID number is a number unique to the individual to which the ID number is assigned. Further, as the identification information, a name, an address, and a contact telephone number considered to be the minimum necessary for identifying the identity are illustrated. Thus, in the identity information DB, the name, address, and contact telephone number of an individual (for example, “Ichiro Sato”) who is assigned the ID number to one ID number (for example, “a001”) are stored. Correspondingly recorded. For example, when the identification information reading device 120 reads the ID number “b001” as the identification information from the identification information recording device 110 affixed to the natural tooth or the like of an unidentified person, this ID number is collated with the identity information DB. So, if an unidentified person can be identified as Mr. Taro Saito who lives in Nagoya, Aichi Prefecture, where the ID number “b001” is assigned, and if he / she contacts “052-123-4567” which is the contact telephone number, You can tell Mr. Taro's family and friends where Mr. Taro Saito is, and ask him if he is really Taro Saito.

  As will be described later, the content of the identity information DB stored in the storage unit 131 is, for example, a change of identity specifying information due to a user's moving, marriage, a change of contact information, etc., a new user (registrant) Can be updated by the DB update unit 137 when there is a situation such as addition of a user or deletion of a user (registrant).

(Communication unit 132)
The communication unit 132 is a function realized by the CPU 130a, the communication device 130c, the connection port 130d, and the like described above. The communication unit 132 can communicate with the identification information reading device 120 via the Internet 13, and can also communicate with the Internet 13 or a wired or wireless LAN 17. It is also possible to communicate with the external connection terminal 140 via, for example.

  The communication unit 132 receives the update information related to addition / change / deletion of the identification information and the identification information provided from the identification information reading device 120 and the external connection terminal 140, and the like, and receives the input unit 133 and the identification information acquisition unit 134. And transmitted to the DB update unit 138 and the like. Further, the communication unit 132 may receive the identification information regarding the unidentified person whose identity has been identified by the verification unit 136 from the verification unit 136 and transmit the received identification information to the external connection terminal 140 or the like. Thereby, the person who is performing the identification process at the identification site can quickly acquire the identification information via the external connection terminal 140 or the like.

(Input unit 133)
The input unit 133 is a function realized by the CPU 130a, the input device 130e, and the like described above, and identifies various information (identification information, update information of the identification information, etc.) input to the identification device 130 by the input device 130e. The data is transmitted to the acquisition unit 134 and the DB update unit 138. For example, when the input person 161 to which the identification information is transmitted from the reader 151 shown in FIG. 1 by the mobile phones 150 and 160 directly inputs the identification information to the identification device 130, the input unit 133 Identification information is input.

(Identification information acquisition unit 134)
The identification information acquisition unit 134 is a function realized by the above-described CPU 130a and the like, acquires identification information from the communication unit 132 or the input unit 133, and transmits the acquired identification information to the collation unit 136 and the identification information recording unit 135. . As described above, the route from which the identification information acquisition unit 134 acquires the identification information includes (1) a route acquired from the input unit 133 by a direct input operation by the input person 161, and (2) the Internet 13 from the identification information reading device 120. There are various routes such as a route acquired from the communication unit 132 that received the identification information via (3) a route acquired from the communication unit 132 that received the identification information from the external connection terminal 140 via the wired or wireless LAN 17 or the like. However, any route may be used as long as the identification information acquisition unit 134 can acquire the identification information as a result.

(Identification information recording unit 135)
The identification information recording unit 135 records the identification information received from the identification information acquisition unit 134 in the storage unit 131. Note that the identification device 130 only needs to be able to identify an unidentified person, and it is not always necessary for the identification device 130 itself to store the identification information of the unidentified person, so this identification information recording unit 135 is optionally provided. Function.

(Verification unit 136)
The collation unit 136 collates the identification information of the unidentified person received from the identification information acquisition unit 134 with the identification information DB stored in the storage unit 131 to identify the identification information of the unidentified person. In addition, the collation unit 136 extracts the identification information of the identified unidentified person from the storage unit 131 and transmits it to the communication unit 132. The identification information transmitted to the communication unit 132 is provided to the external connection terminal 140 and the like by the communication unit 132. Further, the collation unit 136 may transmit the identification information of the identified unidentified person to the identification information output unit 137.

  Here, taking the identity information DB shown in FIG. 7 as an example, the processing performed by the matching unit 136 will be described more specifically. For example, if the identification information acquisition unit 134 acquires the ID number “a002” as the identification information of the unidentified person, the collation unit 136 that receives the ID number “a002” from the identification information acquisition unit 134 first stores the ID number “a002”. The identity information DB is read from the unit 131. Next, the collation unit 136 checks whether or not the ID number “a002” exists in the read identity information DB. As a result, as shown in FIG. 7, since the ID number “a002” exists, identification information corresponding to the ID number, that is, identification information of “Hanako Suzuki” is specified. As a result, it is understood that the unidentified person is Hanako Suzuki, the address of Hanako Suzuki is Osaka City, Osaka Prefecture, and it is only necessary to contact 06-8765-4321. Furthermore, the collation unit 136 transmits the identification information (name, address, contact information, etc.) of “Hanako Suzuki” to the communication unit 132 and the identity information output unit 137.

(Identity information output unit 137)
The identity information output unit 137 is a function realized by the CPU 130a, the output device 130f, and the like described above, and outputs the identity specifying information transmitted from the verification unit 136 to the output device 130f described above as text and / or an image.

(DB update unit 138)
The DB update unit 138 is a function realized by the CPU 130a and the like described above, and is registered in the identity information DB stored in the storage unit 131 based on the update information transmitted from the communication unit 132 or the input unit 133. Rewrite and update existing information. Update information means all of the information that accompanies changes in the identity information DB, but specific examples include requests to change identity-specific information due to moving of the user, marriage, changing contact information, etc., and new users (registration) Information) such as a request to add a user (user) and a request to delete a user (registrant).

≪Attaching method of identification information recording device≫
Subsequently, with reference to FIG. 8 to FIG. 11, a method for attaching the identification information recording apparatus 110 according to the present embodiment to the natural teeth or the like of the user of the identification system 100 (identified person at the identification stage). This will be described in detail. FIG. 8 is a flowchart showing a method of attaching the identification information recording apparatus 110 according to this embodiment. FIG. 9 is a schematic diagram illustrating an example of a pasting method of the identification information recording apparatus 110. FIG. 10 is a photograph showing an example of a pasted part of the identification information recording apparatus 110. FIG. 11 is a photograph showing another example of the pasting part of the identification information recording apparatus 110.

  The method for applying the identification information recording apparatus 110 according to the present embodiment uses the identification information recording apparatus 110 used in the above-described identification system 100 or the identification system described later, and the natural teeth of the user of the identification system 100 are sound. It is a method of sticking to the outer surface of a part, restoration or prosthesis. Hereinafter, a sticking object to which the identification information recording device 110 is stuck, a dental material for sticking the identification information recording device 110 to the sticking object, and an identification information recording device for sticking using the dental material 110 will be described in the order of the sticking method.

[Paste]
The object to be attached to which the identification information recording apparatus 110 according to the present embodiment is attached is a healthy part, a restoration, or a prosthesis of the natural tooth of the user of the identification system 100. Here, the “natural tooth” is a tooth originally possessed by the user. As long as it is a “natural tooth”, it does not matter whether or not there is caries or dental treatment (for example, caries treatment). Further, the “sound part of natural tooth” is a part of the natural tooth that is not caries. The “restoration” is a material that compensates for a missing tooth portion caused by caries treatment or the like, and a composite resin or metal is used as a material. “Prosthetics” includes dentures (all dentures, local dentures, etc.), crowns, bridges, superstructures of implants (artificial roots), etc., and materials such as resins, metals, ceramics, etc. Is used.

[Dental materials]
The dental material that can be used in the present embodiment is not particularly limited as long as it is a material that can be used for dental treatment and can apply the identification information recording device 110 to an object to be pasted. Dental materials such as cement adhesives, dental fillers such as composite resins, adhesive fillers having the functions of dental adhesives and dental fillers, and instant polymerization resins can be used.

  The type of dental adhesive is not particularly limited as long as it is an adhesive used in dental treatment, and an object to be pasted (a healthy part of natural teeth, restoration) to which the identification information recording device 110 is attached. Composite resin, which is a material of the object, resin, metal, ceramic, etc., which is the material of the prosthesis, and the like. For example, when the adherend is a natural tooth, an adhesive material such as a dental adhesive resin cement used when an orthodontic orthodontic appliance made of a material similar to the identification information recording device 110 is attached to the patient's teeth is used. be able to. Further, when it is desired to complete the pasting operation of the identification information recording apparatus 110 in a short time, or when it is necessary to secure a strong adhesive force so that the identification information recording apparatus 110 does not fall out for a long time even if time is required, desired conditions It is preferable to select the type of dental adhesive appropriately according to the situation.

  Further, in this embodiment, when the material to be applied to which the identification information recording device 110 is attached is a healthy part of natural teeth, and the material of the restoration or prosthesis is a resin, the restoration is usually used. A dental filler used for forming (for example, a dental filling composite resin) may be used. In this case, it is preferable to use a dental adhesive that is generally used together with the dental filler, because the adhesive force with respect to the object to be pasted may be insufficient if only the dental filler is used. As such a dental adhesive, an adhesive different from the above-described resin cement or the like is used. For example, an acrylic or methacrylic resin is used as an adhesive component, and a photo-curing type that cures in a short time by light irradiation. Adhesive is used.

  Here, the dental filling material is generally used for filling a missing portion of a tooth or the like generated during a caries treatment or the like. However, in the application method of the identification information recording apparatus 110 in this embodiment, the dental filling is performed without performing any invasive actions such as cutting natural teeth or processing existing restorations and prostheses. The material is used for attaching the identification information recording device 110. As described above, the use of a dental filler used for filling of a tooth defect or the like for the purpose of sticking can be conceived even by a dentist or a person skilled in the dental materials industry. Absent. Moreover, since a dentist uses a dental filler and a dental adhesive that can be used in combination with it in daily clinical practice, it is naturally available. Therefore, the method of using a dental filler and a dental adhesive in combination is simple for most dentists.

  The adhesive filler has an adhesive mechanism similar to that of a resin cement adhesive and includes a filler component such as a composite resin. In this embodiment, the identification information recording device 110 is attached to an object to be pasted. When affixing, it can be used independently like a dental adhesive.

  Furthermore, the immediate polymerization resin is a dental material used for repairing dentures, making temporary teeth, and the like. Since it has adhesiveness with resin-made dentures, artificial teeth, resin crowns, etc., it can be used when attaching the identification information recording device 110. This instant polymerization resin is also easy to use because most dentists always have it.

  Here, in the identification system 100 according to the present embodiment, when the identification information recording device 110 is stuck and fixed to a healthy part of a natural tooth, the surface of a restoration or a prosthesis, the surface of the restoration or the restoration, The periphery of the adherend surface (that is, the surface of a healthy part of a natural tooth, the surface of a restoration or prosthesis, which is in contact with the dental material used for application of the identification information recording device 110) is plaque ( Dental plaque) may adhere. If such a state continues for a long time, caries may be induced. Therefore, for the prevention, it is preferable to use a material having fluorine ion releasing property as the dental material. This material is characterized by the continuous release of fluoride ions into the oral cavity, thus preventing the induction of caries. In particular, when the release rate of fluorine ions is slow (fluorine sustained release), the effect of preventing the induction of caries over a long period can be expected. As dental materials having fluorine ion releasing properties, those commercially available as fluorine sustained-release adhesives and fluorine sustained-release fillers can be used.

  In addition, when a dental filler and a dental adhesive are used in combination as a dental material, a material in which any one of these (that is, a dental filler or a dental adhesive) has a fluorine ion releasing property. Alternatively, both (that is, the dental filler and the dental adhesive) may be a material having a fluorine ion releasing property.

  Even when a dental material having a fluorine ion releasing property as described above is used, the amount of fluorine ions contained in the material is limited, so that fluorine ions are released after a predetermined period. There is a possibility that the effect of preventing caries induction is not exhibited. Therefore, it is more preferable that the dental material used for sticking the identification information recording device 110 has a function of taking in (or recharging) fluorine ions in the oral cavity. The dental material having a fluorine ion recharge function has an action of taking in fluorine ions in the dentifrice by using, for example, a dentifrice containing fluorine ions. In addition, such a dental material having a fluorine ion recharging function can reversibly release (release) and take up (recharge) fluorine ions according to the fluorine ion concentration in the oral cavity. As described above, the use of a dental adhesive having a fluorine ion uptake function induces caries for a longer period of time than when a dental material having a fluorine ion release property (release function) is used. The prevention effect can be sustained.

  Examples of the dental material having a fluorine ion uptake function as described above include dental fillers containing a fluorine-containing glass ionomer filler (for example, “Beautiful II” described above as a commercial product).

  In addition, when the identification information recording device 110 is affixed, it is preferable that the identification information recording device 110 is affixed in a normal state from the viewpoint of aesthetics. For example, when an RF tag having a metal casing is used as the identification information recording apparatus 110, the metal color of the casing is shielded to some extent, and is in harmony with surrounding natural teeth, restorations, prosthesis, etc. It is preferable to use dental materials (such as dental adhesives and dental fillers). In general, when an RF tag having a metal casing is used as the identification information recording apparatus 110, it is preferable to use a dental adhesive or dental filler with a dark eye color. Examples of colors include colors such as A3, A3.5, and A4 of a shade guide (tooth color sample).

[Flow of pasting method]
Next, the flow of the attaching method of the identification information recording apparatus 110 will be described with reference to FIGS. As shown in FIG. 8, the application method of the identification information recording apparatus 110 mainly includes four steps: an application step (S111), an adhesion step (S113), a covering step (S115), and a curing step (S117). Is included. In the following, when only the dental adhesive is used as the dental material, when the dental filler and the dental adhesive are used in combination, and after using the other dental materials in this order, the advantage of this sticking method will be described. This will be described in detail.

(When using only dental adhesive)
When only the dental adhesive is used, as shown in FIG. 8 and FIG. 9A, first, in the application step, a healthy portion, restoration or prosthesis of the natural tooth of the user of the identification system 100 is used. A dental adhesive 31 (31a) such as a resin cement for dental adhesion is applied to the outer surface 20 (the adherend surface, which is a sticking site) (S111). In addition, as a pre-process of this application step, a healthy portion of the natural tooth to which the identification information recording device 110 is pasted, a surface of the restoration or prosthesis (a surface to be applied) is cleaned, and further, the natural tooth In this case, in order to improve the adhesive force with the identification information recording apparatus 110 made of a dental material, it is preferable to acid-treat the adherend surface, which is the application site. Moreover, it is preferable that the application amount of the dental adhesive 31 is as small as possible (assuming that it has sufficient adhesive force). As a result, when the identification information recording device 110 is affixed, the convex portion formed on the adherend surface by the identification information recording device 110 and the dental adhesive 31 can be reduced, so that a foreign body sensation is felt in the oral cavity. Can be reduced.

  Next, in the bonding step, the identification information recording device 110 is bonded to the healthy part of the user's natural teeth, the dental adhesive 31 (31a) applied to the outer surface of the restoration or prosthesis 20 (S113). ).

  Subsequently, in the covering step, the surface of the bonded identification information recording device 110 is applied so as to be covered with the dental adhesive 31 (31b). It applies so that it may become transitional in the shape of the surface of a tooth | gear, a restoration, or a prosthesis (so that the sticking site | part of the identification information recording device 110 may not protrude largely) (S115). By this covering step, the entire periphery of the identification information recording apparatus 110 is covered with the dental adhesive 31 (31a and 31b).

  Finally, in the curing step, the dental adhesive 31 (with fluidity) applied in the application step and the coating step is cured (S117). This curing method differs depending on the type of the dental adhesive 31. When the dental adhesive 31 is cured by ion polymerization, the polymerization reaction is waited for a predetermined time or the dental adhesive 31 is radically polymerized. In the case of curing by (photopolymerization), for example, the dental adhesive 31 is cured by light irradiation using a halogen irradiator or an LED irradiator (light irradiator).

  As described above, when only the dental adhesive is used, the adhesive part (dental adhesive 31a) and the covering part (dental adhesive 31b) are made of the same material and have compatibility. The boundary portion between the material 31a and the dental adhesive 31b is sufficiently adhered. Therefore, the entire periphery of the identification information recording apparatus 110 can be reliably covered with the dental adhesive 31. As a result, a waterproofing effect (an effect that prevents the identification information recording device 110 from touching moisture) is provided, and the identification information recording device 110 can exhibit its function stably for a long period of time. Further, by covering the entire periphery of the identification information recording device 110 with the dental adhesive 31, when the user eats, hard food or the like comes into direct contact with the identification information recording device 110, and the identification information recording device 110 is There is also an effect of preventing falling off or breakage. In addition, the smaller the identification information recording device 110 is, the smaller the amount of application of the dental adhesive 31 even if it is entirely covered with the dental adhesive 31. It can be expected that the feeling is reduced and the induction of caries is also suppressed.

  Further, in the method of using a dental filler and a dental adhesive, which will be described later, depending on the type of dental material used, an identification information recording device for a material (a paste object) such as metal or ceramic (porcelain). 110 may not be attached (adhered). In such a case, the identification information recording apparatus 110 can be reliably affixed to the object to be adhered by a method using only the above-mentioned dental adhesive having an adhesive strength to metal, ceramic (porcelain) or the like. .

(When using dental filler and dental adhesive together)
When the dental filler and the dental adhesive are used in combination, as shown in FIGS. 8 and 9B, first, in the application step, a healthy part of the natural tooth of the user of the identification system 100, A dental adhesive 35 such as an acrylic or methacrylic adhesive is applied to the outer surface of the restoration or prosthesis 20 (the adherend surface, which is the application site) (S111). As in the case of using only the dental adhesive, it is preferable to clean the adherend surface, which is the application site, as a pretreatment for this application step, and to perform acid treatment for natural teeth. In general, after the dental adhesive 35 is applied, the dental adhesive 35 is cured by photopolymerization or the like before the dental filler 33 is applied.

  Further, in the case of combined use, in a coating step, a dental filler 33 (33a) such as a composite resin is further coated on the surface of the dental adhesive 35 (S111). In addition, it is preferable that the application amount of the dental filler 33 and the dental adhesive 35 is as small as possible.

  Next, in the adhering step, the identification information recording device 110 is adhered to the dental filler 33 (33a) applied to the healthy portion of the user's natural teeth, the outer surface of the restoration or prosthesis 20 (S113). ).

  Subsequently, in the covering step, the surface of the bonded identification information recording device 110 is applied so as to be covered with the dental filler 33 (33b). In this case as well, as in the case of using the dental adhesive described above. Then, it is applied so as to be transitional to the surface of the surrounding natural tooth, restoration or prosthesis so as not to feel a foreign body feeling in the oral cavity after curing (S115). By this covering step, the entire periphery of the identification information recording apparatus 110 is covered with the dental filler 33 (33a and 33b).

  Finally, in the curing step, the dental filler 33 (with fluidity) applied in the application step and the coating step is cured (S117). This curing method can be cured mainly utilizing radical polymerization (photopolymerization) reaction.

  As described above, when the dental filler 33 and the dental adhesive 35 are used in combination, the adhesive portion (dental filler 33a) and the covering portion (dental filler 33b) are the same material and are compatible. Therefore, the boundary portion between the dental filler 33a and the dental filler 33b is sufficiently adhered. Therefore, the entire periphery of the identification information recording apparatus 110 can be reliably covered with the dental filler 33. As a result, a waterproof effect is imparted, and the identification information recording device 110 can exhibit its function stably for a long period of time. Further, by covering the entire periphery of the identification information recording device 110 with the dental filler 33, when the user eats, hard food or the like comes into direct contact with the identification information recording device 110, and the identification information recording device 110 There is also an effect of preventing falling off or breakage. In addition, the smaller the identification information recording device 110 is, the smaller the amount of application of the dental filler 33 can be even if it is entirely covered with the dental filler 33. It can be expected that the feeling is reduced and the induction of caries is also suppressed.

(Other dental materials)
In this embodiment, the above-mentioned adhesive filler, immediate polymerization resin, or the like can be used as the dental material. Also in this case, as in the case of using a dental adhesive, the identification information recording device 110 can be attached to an adherend to which the identification information recording device 110 can be bonded using an adhesive filler, an immediate polymerization resin, or the like alone. Since the specific sticking method in the case of using an adhesive filler, an immediate polymerization resin, etc. is the same as that in the case of using a dental adhesive, detailed description thereof is omitted here.

  In addition, when selecting the kind of dental material used by this form, it considers whether it has adhesiveness with respect to the material etc. of a sticking object. It is also preferable to examine the curing rate. For example, when a dental material having a high curing speed is used, the user can use the identification system 100 for a short period of time to open the mouth for attaching the identification information recording device 110, and thus the operability is good. Further, if the mouth is opened for a long time, saliva tends to accumulate, and if saliva adheres to the adherend surface, the adhesive force of the dental material may be reduced. Therefore, it is preferable to use a fast-curing dental material in order to reliably attach the identification information recording apparatus 110 to an object to be stuck.

(Advantages of this application method)
When the identification information recording apparatus 110 is no longer required after application by applying the above application method and applying the identification information recording apparatus 110 to the user's natural teeth or the like using dental materials, Unlike the implantable type, it can be easily removed if an appropriate treatment is performed by a dentist or the like.

  Thus, in the identification system 100 according to the present embodiment, identification is performed without performing any invasive action such as cutting a healthy part of the user's natural teeth or processing a restoration or prosthesis. The information recording device 110 is detachably attached (attached), and it can be said that the attachment of the identification information recording device 110 in this embodiment is a non-invasive treatment. “Non-invasive” as used herein refers not only to not damaging the user's body, such as shaving the user's natural teeth, but also to restorations installed in the user's mouth. This also means that no processing (processing that involves deformation) is applied to an artificial object such as a prosthesis. In other words, “non-invasively applying” the identification information recording device 110 means that the healthy part of the natural tooth, the restoration or the prosthesis is not deformed or processed at all, and is applied in the same state as before application. Is to do.

  Therefore, in the identification system 100 according to the present embodiment, even if the identification information recording device 110 is once pasted and then the identification information recording device 110 is removed, a healthy portion of a natural tooth, a restoration or a prosthesis Can hold the same state as before the identification information recording device 110 is pasted. That is, the method of applying the identification information recording apparatus 110 employed in the identification system 100 according to the present embodiment can be said to be a “reversible” method, and this point is employed in the above-described Patent Documents 1 to 4. Needless to say, this is largely different from the embedded method and cannot be achieved by the conventional embedded method.

  As described above, the identification system 100 according to the present embodiment (and the method of applying the identification information recording device 110 employed in the system) has the advantages of being “non-invasive” and “reversible”. Therefore, it is expected that the user will have much less resistance than the conventional one.

(Attachment site)
Next, the suitable pasting site | part of the identification information recording device 110 in this form is demonstrated.

  There are not many examples that have been studied so far on the attachment site (in this embodiment, the attachment site) of the identification information recording device 110 such as an IC chip. It is considered optimal to attach an ID device such as an IC chip to the molar part.

  However, according to a study by the present inventor, for example, when an IC chip is provided in the back part of the oral cavity such as a molar part, recognition of whether or not the IC chip is attached to the user (unidentified person) It became clear that there was a problem that it was difficult to find the mounting position. In particular, when an unidentified person cannot open his / her mouth greatly due to rigidity after death, it is difficult to confirm the site in the mouth of the unidentified person. In addition, when the size of the IC chip is very small, it becomes more difficult to recognize and find the IC chip.

  From the above examination, the present inventor recognizes (discovers) how easily the identification information recording device 110 attached to the oral cavity of the user when the identification information recording device 110 is used for identification. (Hereinafter, such a problem is referred to as “recognition”).

  On the other hand, as a result of further studies by the inventor, users of a system such as the identification system 100 do not live on the assumption that they are unidentified in the first place. It turned out that the aesthetic aspects of his mouth are also important. That is, the present inventor, contrary to the above-mentioned problem of recognizability, makes the identification information recording device 110 attached in the user's oral cavity inconspicuous (inconspicuous) (hereinafter, this problem is described as “ Also called “aesthetic”.) Was also found to be very important in daily life.

  As described above, when performing identification using the identification information recording device 110 such as an RF tag (IC chip) installed in the oral cavity, the problems of conflicting “recognition” and “aesthetics” are simultaneously encountered. It is important to solve. However, until now, as a technique for identifying the identity by using the identification information recording device 110 such as an RF tag (IC chip), those that have focused on the conflicting problems of the above-mentioned “recognition” and “aesthetics” It does not exist (the “recognition” and “aesthetic” are not considered at all even when the mounting position of the ID device is examined in Patent Document 4).

  Therefore, the present inventor has proceeded with a study on an application site of the identification information recording apparatus 110 that can simultaneously solve the conflicting problems of “recognition” and “aesthetics”. As a result, the identification information recording device 110 is able to detect the lip side surface (front side) of the front tooth part or the premolar part in the healthy part, restoration or prosthesis of the natural tooth of the user (unidentified person) of the identification system 100. The knowledge that it was suitable to affix to the buccal side (front side) was acquired. Here, the “front tooth portion” means a portion from the central incisor to the canine. More preferably, the position of the canine or the first premolar is particularly excellent in “recognition” and “aesthetic”. In addition, if the person has poor tooth alignment, by using the unevenness of the tooth alignment of the front tooth portion, the identification information recording device 110 is affixed to a portion of the front tooth portion where the identification information recording device 110 is not noticeable in daily life. "And aesthetics" can also be achieved.

  In addition, it is thought that “recognition” and “aesthetics” can be made compatible by attaching the identification information recording device 110 to the lingual side (back side) of the front tooth part. Since the tongue easily touches the information recording device 110, the sense of foreign matter is strong and is not very suitable. In addition, if the identification information recording device 110 is affixed to the back side of the maxillary anterior tooth portion, the anterior teeth of the lower jaw may bite, and the identification information recording device 110 may be dropped or damaged. Furthermore, the back side of the mandibular front tooth part is a part where tartar is particularly likely to accumulate even in the oral cavity, and if the identification information recording device 110 is affixed to this part, there is a risk of inducing caries or periodontal disease.

  On the other hand, by attaching the identification information recording device 110 to the labial surface (front side) of the front tooth part or the buccal side surface (front side) of the premolar part, both “recognition” and “aesthetics” can be achieved. It is possible to eliminate the “foreign object sensation” as much as possible and to prevent the identification information recording apparatus 110 from being dropped or damaged. Furthermore, since the user himself / herself of the identification system 100 can easily confirm the application position of the IC chip, it is possible to prevent induction of dental caries and periodontal disease by daily brushing.

  In addition, by attaching the identification information recording device 110 to the healthy part of the natural tooth of the front tooth part or the premolar part, the outer surface of the restoration or prosthesis, and attaching to the back part such as the molar part In comparison, the mounting operation of the identification information recording apparatus 110 is also greatly facilitated.

  Further, depending on the type of IC chip to be used, the communicable distance between the identification information recording device 110 (for example, an RF tag) and the identification information reading device 120 (for example, a reader / writer in RFID) is short (for example, 1 to 2 cm). Degree) in some cases. Even in such a case, the identification information reading device 120 can reliably read the identification information by attaching the identification information recording device 110 to a portion close to the lip, such as the front tooth portion or the premolar portion.

  In addition, if the identification information recording device 110 is affixed to the molar portion, when the user of the identification system 100 eats, hard food or the like directly comes into direct contact with the identification information recording device 110, and the identification information recording device 110 Is easily dropped or damaged. In the first place, the molar part is a part where a strong force acts when biting compared to the anterior part and the premolar part, and a strong force is applied to the molar part through hard food. Therefore, when the identification information recording device 110 is affixed to the molar portion, the risk of dropping or damaging the identification information recording device 110 due to contact with hard food or the like is greater than when the identification information recording device 110 is affixed to the anterior or premolar portion. It will be much higher.

  Here, referring to FIGS. 10 and 11, an example of examining a suitable pasting site of the identification information recording apparatus 110 will be described.

  In general, teeth are most noticeable (exposed) when you laugh with your mouth open. Even when laughing at the same time, conspicuous tooth sites differ depending on age, gender, upper and lower jaw shapes, tooth arrangement, and the like. Therefore, an example in which a 2.5 mm square RF tag is actually attached to two persons of different ages and genders using a dental filler and a dental adhesive as the identification information recording device 110 will be described. FIG. 10 shows an example of a woman in her 20s, and FIG. 11 shows an example of a man in her 50s. In FIGS. 10 and 11, (a) and (b) are photographs showing how the teeth and the RF tag are seen when a normal laughter is performed, and (c) and (d) are for identifying the identity. It is a photograph showing how the teeth and the RF tag are seen when the lips are slightly expanded so as to expose the site where the RF tag is applied.

  In the example of a woman in his twenties shown in FIG. 10, the front teeth of the upper jaw were conspicuous when laughing. For this reason, if an RF tag is affixed to the upper jaw, there is no problem with the recognizability, but it will be inferior in aesthetics. Therefore, the RF tag was affixed to the labial surface (the direction away from the midline, the back tooth side) of the lower lip side of the lower right canine and the buccal side of the lower first left premolar. As a result, as shown in FIGS. 10 (a) and 10 (b), when a normal laughter is made, the front teeth of the lower jaw are not exposed so much that the RF tag cannot be recognized. From this, it can be said that it is excellent in aesthetics. On the other hand, as shown in FIGS. 10 (c) and 10 (d), when the lips are opened to expose the lower canine teeth and premolars assuming identification, the RF tag can be easily recognized. I was able to. Therefore, it can be said that the recognition is high.

  Further, in the example of a man in his 50s shown in FIG. 11, the front teeth of the lower jaw were conspicuous when laughing. Therefore, it is considered that when an RF tag is attached to the lower jaw, there is no problem in recognition, but it is inferior in aesthetics. Therefore, the RF tag was affixed to the distal surface of the lip of the upper canine. As a result, as shown in FIGS. 11 (a) and 11 (b), when an ordinary laughter is made, the front teeth of the upper jaw are not exposed so much, and the RF tag cannot be recognized. From this, it can be said that it is excellent in aesthetics. On the other hand, as shown in FIGS. 11 (c) and 11 (d), the RF tag could be easily recognized when the lips were opened to expose the maxillary canine, assuming identification. . Therefore, it can be said that the recognition is high.

  As described above, in any of the above-mentioned examples, in any person, when the RF tag is attached to the distal surface of the lip of the canine or the buccal side of the premolar, both recognition and aesthetics can be achieved. did it. However, these are merely examples, and the identification information recording apparatus 110 may achieve both recognizability and aesthetics according to the age, gender, upper and lower jaw forms, teeth arrangement, etc. of the user of the identification system 100. What is necessary is just to affix on a site | part.

≪Identification method≫
Next, with reference to FIG. 12, the identification information recording apparatus 110 affixed to the natural teeth of the user (unidentified person) by the above-described mounting method, that is, the identification method read out, An identification method using the identification system 100 including the device 120 and the identification device 130 will be described in detail. FIG. 12 is a flowchart showing an identification method according to this embodiment.

  The identification method according to the present embodiment is a method mainly including a reading step, an acquisition step, and a collation step, and may further include an output step. Hereinafter, each step will be described in detail.

[Reading step]
In the reading step, the identification information reading device 120 reads the identification information recorded in the identification information recording device 110. More specifically, as shown in FIG. 12, the communication unit 123 of the identification information reading device 120 puts the identification information request signal on radio waves or electromagnetic waves, and is attached to the natural teeth or the like of an unidentified person. The data is transmitted to the recording device 110 (S151).

  When the identification information recording device 110 receives this request signal (S153), the IC chip 110b of the identification information recording device 110 is activated by the radio wave or electromagnetic wave carrying the request signal (S155). When the IC chip is activated, the communication unit 113 transmits the received request signal to the identification information extraction unit 115, and the identification information extraction unit 115 that receives the request signal extracts the identification information of the unidentified person from the storage unit 111 ( In step S157, the data is transmitted to the transmission unit 113. Next, the transmission unit 113 transmits the received identification information on the radio wave or electromagnetic wave to the identification information reading device 120 (S159).

  When the communication unit 123 of the identification information reading device 120 receives the identification information of the unidentified person from the identification information recording device 110 (S161), the communication unit 123 transmits the radio wave or electromagnetic wave carrying the identification information to the identification information extraction unit 125. To do. Further, the identification information extraction unit 125 extracts identification information from radio waves or electromagnetic waves, and transmits the extracted identification information to the identification information recording unit 127, the identification information output unit 129, and the communication unit 123. If necessary, the identification information recording unit 125 temporarily stores the identification information in the storage unit 121, or the identification information output unit 129 outputs the identification information to the output device 120e (S163). In addition, the communication unit 123 transmits the identification information to the identification device directly or via the external connection terminal 140 (S167).

[Acquisition step]
In the acquisition step, the identity identification device 130 acquires the identification information read by the identification information reading device 120. More specifically, as shown in FIG. 12, the communication unit 132 of the identification device 130 receives the identification information from the identification information reading device 120 or the external connection terminal 140, or the identification information is identified by the input unit 133. When input to the specific device 130, the communication unit 132 or the input unit 133 transmits the identification information to the identification information acquisition unit 134, whereby the identification information acquisition unit 134 acquires the identification information (S167). Further, the identification information acquisition unit 134 transmits the acquired identification information to the identification information recording unit 135 and the verification unit 136.

[Verification step]
In the collation step, the identity identifying device 130 collates the acquired identification information of the unidentified person with the identity information DB, and identifies the identity identifying information associated with the identification information of the unidentified person. More specifically, as shown in FIG. 12, when the collation unit 136 receives the identification information from the identification information acquisition unit 134, the collation unit 136 reads the identity information DB from the storage unit 131 (S169). Next, the collation unit 136 collates the identification information with the identity information DB read in step S169, and identifies the identity specifying information of the unidentified person (S171). The collation unit 136 may extract the identification information of the identified unidentified person from the storage unit 131 and transmit it to the communication unit 132. The communication unit 132 may further provide identification information to other devices through the Internet 13, a wired or wireless LAN 17, or the like.

[Output step]
In the output step, the identity identifying device 130 outputs the identified identity identifying information through an output device 130f (for example, a display device, a speaker, a printer, etc.) installed or connected to the device so that it can be recognized externally. More specifically, as shown in FIG. 12, when the collation unit 136 transmits the identification information of the identified unidentified person to the identification information output unit 137 as necessary, the identification information output unit 137 receives the identification information. The identity information is output to the output device 130f (S173).

≪Others≫
[Periodic inspection of identification information recording device 110 and dental examination]
The identification information recorded in the identification information recording device 110 after a predetermined period of time has elapsed since the identification information recording device 110 was affixed to a healthy portion of the user's natural tooth, restoration or prosthesis. It is preferable to periodically check whether or not can be read. This is to prevent the identification information from being unreadable due to a failure or breakage of the identification information recording device 110 during actual identification. In addition, since the dental material for attaching the identification information recording device 110 to the user's natural teeth or the like cannot be permanently maintained, whether or not the adhesive force of the dental material is maintained. It is preferable to confirm. Furthermore, by making such a check regular, and also performing a checkup of the user's teeth at that time, the user of the identification system 100 can prevent periodontal disease and caries. It becomes possible.

[Safety of identification system 100]
Further, since it is a dental material that attaches the identification information recording device 110 to a healthy portion, restoration or prosthesis of a natural tooth of a user of the identification system 100, a dentist can use a treatment instrument, etc. It can be easily removed using On the other hand, since it is extremely difficult for the user himself / herself to remove the identification information recording device 110 by himself / herself, the user himself / herself has lost the identification information recording device 110, and as a result, the device has been lost. Can be prevented from leaking to third parties. As described above, in the identification system 100 according to this embodiment, only the dentist can attach and detach the identification information recording device 110. Therefore, the identification system 100 can identify the identification information and the identification information. It can be said that the system is safe in terms of management.
