The present invention relates to an access control system, and more particularly, to an access control system capable of access control without accessing a server on a network, a fingerprint reader used therein, a memory card capable of interfacing data with the fingerprint reader, .

Unlike a lock that can be opened using a key, a card, or a password, the "access control system using a fingerprint" is a system that can easily open a door through fingerprint recognition, which is one of biometrics fields. It is an advanced electronic control access control system with security.

A general access control system using a fingerprint includes a door lock controller installed in a door to control a lock of a door to a fingerprint recognizer that receives a user's fingerprint and recognizes the fingerprint, .

However, in the illustrated system, since a fingerprint recognizer incorporating a controller for controlling the lock of the door must be installed for each door, as the number of doors increases, the cost of system construction increases and the size of the fingerprint reader itself is limited .

A system developed to solve this problem is an access control system as shown in FIG.

The fingerprint recognizer 10 shown in FIG. 1 is a device installed on a door to interface with a user who desires to enter and exit. The fingerprint reader 10 receives fingerprint information and user information from a user, authenticates the user, . The fingerprint recognizer 10 includes a memory for storing user fingerprint information therein.

On the other hand, the door lock 20 installed on each door opens and closes the door in accordance with the control command of the door lock controller 30. The door lock 20 is connected to one door lock controller 30 as shown in FIG.

The door lock controller 30 manages a predetermined number of fingerprint recognizers 10 and door locks 20 and receives user authentication data from each fingerprint reader 10 through a data transmission protocol such as RS-422 or TCP / IP And controls the door lock 20 to open and close. The door lock controller 30 includes a first data communication unit for performing communication with the fingerprint recognizer 10 and a second data communication unit for performing data communication with the management server 40 controlling the plurality of door lock controllers 30 And a second data communication unit.

The number of the door lock controller 30 is required as the number of the fingerprint recognizer 10 and the door lock 20 increases. In order to manage the door lock controller 30 more efficiently, ) Is required.

The management server 40 monitors the state of the door locks 20 in real time through the door lock controller 30 and controls the system integrally. And receives event information generated from the fingerprint recognizer 10 through the door lock controller 30 to monitor the access status and intruder occurrence of each door. In addition, the administrator registered as a master can generate, change or delete information of each fingerprint recognizer 10 through the server 40. [ The server 40 performing such a function transmits and receives signals through a plurality of door lock controllers 30 and a data transmission protocol such as TCP / IP or RS-422.

However, this system can lower the system construction cost compared to the system using only the fingerprint recognizer, and also can downsize the size of the fingerprint reader itself. However, since it involves construction for relatively network installation, And there is a limit to simplify the system configuration because a server installation and network construction for connection with the server must be performed.

In addition, it is necessary to set various parameters of the fingerprint recognizer through the server, and to grant ID authorization, which also involves administrative troubles.

For example, the command information may be a user's new registration command, a fingerprint information deletion command, a variable setting command, or a memory card issuing command. The auxiliary data may include user ID information, variable information, User fingerprint information, and the like.

In other words, the administrator can issue and hold a memory card on which a new user registration instruction word is recorded through the PC on which the above-described application is installed, issue a memory card or the like on which an instruction for instructing deletion of the registered user's fingerprint is recorded, So that the recognizer 200 can be controlled and managed.

Unlike the above-described manager-use memory card, the general user's memory card includes a header area in which header information is recorded, a user identification information area in which user identification information is recorded, And a user fingerprint information area in which fingerprint information necessary for user authentication is recorded. Such a user memory card can be issued through a fingerprint recognizer 200, which will be described later, and can also be issued through a manager PC.

Hereinafter, a memory card 400 having the above-described configuration and a fingerprint reader 200 capable of data interfacing will be described in detail.

First, the fingerprint recognizer 200 according to an embodiment of the present invention basically includes basic configurations necessary for authenticating a user, that is, information recorded in the memory card 400, for example, fingerprint information of a user or a manager, And a card access unit 210 for reading information (fingerprint information) on the card. The information read by the card access unit 210 is applied to the command extracting unit 220 and the user authentication unit 225, which will be described later.

The fingerprint recognizer 200 further includes a fingerprint recognition unit 215 for recognizing the user fingerprint and processing the user fingerprint as fingerprint recognition information. As already known, the fingerprint recognition unit 215 includes a light source (not necessary for a semiconductor type) for acquiring fingerprint information, a fingerprint sensor, and an image processor for finally obtaining fingerprint recognition information from the sensed image.

Further, the fingerprint recognizer 200 extracts fingerprint information from the information read through the card access unit 210, compares the fingerprint information with the fingerprint recognition information recognized by the fingerprint recognition unit 215, and outputs user authentication data And a data communication unit 240 for interfacing the user authentication data with an external device. For reference, the user authentication data output from the user authentication unit 225 may be directly output through the data communication unit 240, but may be output through a command processing unit 230 described later.

For reference, the user authentication unit 225 may record event information on administrator or user authentication results in the internal storage unit and manage the event information. The result of the authentication is recorded in the memory card 400 and can be confirmed by other devices such as a PC.

In addition to the basic configuration described above, the fingerprint recognizer 200 is a unit for processing commands recorded in the manager memory card, and includes a command extracting unit 210 for extracting command information from the information read through the card access unit 210, And a command processing unit 230 for processing the auxiliary data read from the card according to the extracted command information.

More specifically, when the extracted command information is a new registration command, the command processing unit 230 performs the fingerprint authentication of the administrator through the user authentication unit 225, The fingerprint information is stored in the internal storage together with the user identification information (ID). The command processing unit 230 may further output the user identification information (ID) read from the inserted new memory card 400 to the door lock controller 100 as an external device.

Furthermore, when the extracted command information is a fingerprint information delete command, the command processing unit 230 performs administrator fingerprint authentication through the user authentication unit 225, and then, The fingerprint information is deleted from the storage unit. The command processing unit 230 may output the user identification information (ID) read from the card to the door lock controller 100 as an external device together with the fingerprint information delete command.

In addition, if the extracted command information is a variable setting command, the command processing unit 230 may perform administrator fingerprint authentication through the user authentication unit 225 and set a system variable as a variable read from the card, If the command information is the memory card issuing command, the manager fingerprint authentication is performed through the user authentication unit 225 and then the fingerprint recognition information recognized by the fingerprint recognition unit 215 is transmitted to the issuing memory card 400, (To control the card access unit).

The administrator can write commands or variables necessary for controlling the door lock controller 100 or the fingerprint recognizer 200 and transmit them to the destination by issuing and issuing the necessary commands in addition to the commands described above to the administrator's memory card 400 and issuing them.

Reference numeral 245 in FIG. 3 denotes a user interface unit, which includes a keypad including a plurality of numerals and function keys, and a display unit for displaying an operation state. The user interface unit exposes the current state of the fingerprint recognizer to the outside under the control of the control unit provided in the general fingerprint recognizer.

Hereinafter, how the manager memory card and the general user memory card 400 according to the embodiment of the present invention are utilized in the access control system as shown in FIG. 2 will be described in more detail.

5 is a diagram illustrating a process of newly registering a user using the memory card 400 according to an embodiment of the present invention.

5, in order to newly register a user, the manager inserts the manager memory card 400 including the new registration command into the card insertion slot (in the case of the contact type) of the fingerprint recognizer 200. When the memory card 400 is inserted in this way, the card access unit 210 reads the information recorded in the memory card 400 (S1). The read information is transmitted to the command extracting unit 220, so that the command processing unit 230 receives the command information through the command extracting unit 220. If the received command is a new registration command (S2), the command processing unit 230 performs the fingerprint authentication of the administrator through the user authentication unit 225 (S3).

For fingerprint authentication of the administrator, the command processing unit 230 requests the fingerprint scan of the administrator through the user interface unit 245. Accordingly, when the administrator leaves his or her fingerprint on the fingerprint recognition unit 215, the fingerprint of the manager is signal-processed by the fingerprint recognition unit 215 and transmitted to the user authentication unit 225 as one fingerprint recognition information. Then, the user authentication unit 225 compares the manager fingerprint information read through the card access unit 210 with the fingerprint recognition information applied through the fingerprint recognition unit 215, and if it matches, the authentication data indicating the state thereof, The manager fingerprint authentication process is completed.

When the manager fingerprint authentication is normally completed, the command processing unit 230 requests insertion of the memory card 400 to be newly registered (S4). Upon inserting the memory card 400 of a general user who wishes to newly register in response to the request, the command processing unit 230 determines whether the fingerprint information of the user who has been read through the card access unit 210 Information is stored in a storage unit provided therein or transmitted to the door lock controller 100 (S6). When the user identification information and the fingerprint information are registered in the fingerprint recognizer 200, access by the user authentication can be permitted without the memory card 400, and the user identification information and the fingerprint information are stored in the door lock controller 100 It is possible to restrict user access even if registered.

For reference, the user identification information (and fingerprint information) transmitted to the door lock controller 100 is stored in the user DB and is available.

If a user inserts his or her memory card 400 into the fingerprint recognizer 200 while assuming that a plurality of pieces of user information are registered in the door lock controller 100 through the above method, The control unit 225 extracts the fingerprint information from the information read through the card access unit 210 and compares the extracted fingerprint information with the fingerprint recognition information recognized by the fingerprint recognition unit 215 and transmits the user authentication data to the command processing unit 230 Output. When the user authentication data is transmitted to the door lock controller 100 in the form of user identification information, the door lock controller 100 controls the door lock 300 of the place where the fingerprint reader 200 is installed when the user authentication data is received , The user can finally be allowed to enter the predetermined space.

In a similar manner, if the command read from the manager memory card 400 is a memory card issuance command, the command processor 230 performs manager fingerprint authentication through the user authentication unit 225 as described above, By processing the fingerprint recognition information recognized by the fingerprint recognition unit 215 through the writer of the card access unit 210 to store it in the issue target memory card, the new user can input his / her fingerprint and user identification information The memory card 400 can be issued. Of course, the card issuing application can be issued through a PC installed.

Furthermore, if the command read from the manager memory card 400 is a variable setting command, the command processing unit 230 performs administrator fingerprint authentication through the user authentication unit 225, You can also set system variables.

Furthermore, the user authentication unit 225 records event information on the authentication results in the storage unit, and such event recording information can be accessed again by an event record extraction command. That is, if the command read from the manager memory card 400 is an event record extraction command, the command processing unit 230 writes the event recording information recorded in the storage unit to the conditional statement (event type, period, user, etc.) And is then written to a new event storage card.

That is, in the access control system according to the embodiment of the present invention, the user can be authenticated and access restricted without storing the fingerprint information of the user, It is possible to normally perform operations such as new user registration, registered fingerprint information deletion processing, variable setting of the fingerprint reader itself, issue of a user new memory card, and event record extraction through only the card 400.

As described above, according to the present invention, a user or administrator authentication can be performed by comparing the fingerprint information recorded on the memory card with the fingerprint recognized through the fingerprint recognition unit. Therefore, a separate fingerprint DB for user authentication is not needed, In addition, it can be economically effective in terms of cost,

Furthermore, since the fingerprint recognizer can handle additional service tasks such as new user registration, deletion of registered user information, system parameter setting, new card issuance, etc. without the need of supporting a separate server, the network configuration can be simplified, It is possible to provide convenience of convenience.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. For example, although the access control system using the memory card as the memory means is exemplified in the embodiment of the present invention, the fingerprint information and the command information are recorded in the portable storage device (corresponding to the memory means) such as the external memory, The access control system according to the embodiment of the present invention may be provided. Accordingly, the true scope of the present invention should be determined only by the appended claims.
