detailed description

The present invention will be further described in detail below in conjunction with the drawings.

Fig. 1 schematically shows a functional block diagram of an anti-counterfeiting system according to an embodiment of the present invention, as shown in Fig. 1,

The anti-counterfeiting system includes: an identification module 1 and an anti-counterfeiting module 2. The identification module 1 is used to obtain identification information and anti-counterfeiting information from the anti-counterfeiting code set on the terminal device, and output to the following anti-counterfeiting module 2; the anti-counterfeiting module 2 is set in the remote device to receive the identification information and anti-counterfeiting information for authenticating And generate the authentication result and output it to the recognition module 1. The identification module 1 can be set on terminal devices such as mobile phones and tablet computers. For example, when the identification module 1 is set, an application corresponding to the mobile phone system (such as Android, Iphone) is developed through the existing technology, and the mobile phone comes with Camera to scan the security code. The anti-counterfeiting module 2 can be deployed on a remote server. Since the anti-counterfeiting module 2 is deployed on the server, it is much more difficult to break a server than a fixed program. Therefore, compared with the anti-counterfeiting code of the prior art The system has higher security. The identification module 1 and the anti-counterfeiting module 2 are arranged at different ends and can communicate wirelessly.

The anti-counterfeiting code provided in this embodiment, as shown in FIG. 3, includes: an identification area 3 and an anti-counterfeiting area 4. The identification area 3 is used to place identification information. The anti-counterfeiting area 4 is used to place anti-counterfeiting information. The identification area 3 and the anti-counterfeiting area 4 are arranged according to a preset spatial structure, that is, the anti-counterfeiting area 4 is arranged inside the identification area 3. In order to improve the information contained in the identification area 3 and the anti-counterfeiting area 4 as much as possible, in other preferred embodiments, as shown in FIG. 4, the spatial structure can also be implemented as setting a part of the anti-counterfeiting area 4 in the identification area 3. Inside, the other part is set around the identification area 3, that is, a part of the anti-counterfeiting area is set inside the identification area, and the other part is set around the identification area, that is, the anti-counterfeiting area is divided into five areas, and the identification area is a single whole. Set up an anti-counterfeiting area inside the identification area, and set up an anti-counterfeiting area around the identification area, which can contain a lot of information. In other preferred embodiments, as shown in FIG. 5, the space structure can also be implemented as setting the anti-counterfeiting area 4 around the identification area 3, that is, the identification area is regarded as a single whole, and the anti-counterfeiting area is divided into four parts, respectively. Around the identification area.

Wherein, the spatial structure of the identification area is divided into non-overlapping identification blocks during construction, and identifiers are filled in corresponding positions of each identification block to form binary data; the binary data is sliced to generate information for identification. Exemplarily, each identification block is used to represent 1 bit of information. If the identifier filled in the identification block is black, it means 1, and when it is white, it means 0, and these identification blocks form binary data of a certain length. Afterwards, the binary data is fragmented (the specific implementation method can refer to the prior art implementation), which can be used to express a large amount of information. The information used for identification includes first identification information, and the first identification information includes an encoding method, an encoding version, positioning information, and color information of the anti-counterfeiting area. Exemplarily, the first 4 bits of the binary data are used to indicate the encoding method of the anti-counterfeiting code, and the 5th to 8th bits are used to indicate the encoding version of the anti-counterfeiting area. Specifically, the anti-counterfeiting area coding method and the anti-counterfeiting area coded version are used to assist the terminal or server that authenticates the anti-counterfeiting code to decode its anti-counterfeiting area information. The positioning information is used to describe the relative position of the anti-counterfeiting area and the identification area, and the size of the anti-counterfeiting area (the number of pixels in the width and height of the anti-counterfeiting area). Color information is used to describe the color system used in the anti-counterfeiting area, such as Black-White, YUV, RGB, HSV, etc. The specific spatial relationship between the anti-counterfeiting area and the recognition area is also reflected in the mapping relationship between the anti-counterfeiting area and the recognition area through the positioning information, so that the anti-counterfeiting information can be extracted through the positioning information and color information, and when extracting the anti-counterfeiting information, pass The color information in the identification information can obtain the image information of the anti-counterfeiting area corresponding to the identification area, that is, the encrypted anti-counterfeiting information, which effectively improves the security of the anti-counterfeiting code. Exemplarily, for the Black-White color system, the acquired image data is only about 600 bytes, plus a small amount of color information data and frame data, which does not exceed 1 kB in total. For the recognition process, the occupied network bandwidth is extremely low, which can effectively improve the recognition speed. The information used for identification also includes second identification information. The second identification information includes an information error correction code and an information verification code, which are used to identify and distinguish the identification area. Illustratively, the identification area is divided into a candidate identification area and a valid identification. Area, the candidate identification area is configured to include the first identification information, and the effective identification area is configured to include the first identification information and the second identification information. In specific applications, the candidate identification area can be scanned and searched, and the second Identification information verification to distinguish and determine the effective identification area. The process of determining the effective identification area through the candidate identification area is specifically realized as: searching for the candidate identification area information to determine, if the identification information of the candidate identification area can perform information code error correction by itself, and also pass its own information check code verification, Then the candidate identification area is used as the effective identification area, that is, the first identification information can be corrected and verified by the detected second identification information, which means that the area includes both the second identification information and the first identification information. That is to determine the area as a valid recognition area. Wherein, the identification of the candidate area can be achieved by setting the structure of the candidate area and performing scanning judgment on the structure. For example, the candidate area is implemented as including four candidate positioning points forming an approximate matrix. The candidate anchor point is: if there are at most m other black points in a circle with a black point as the center and radius n, then the black point is a candidate anchor point, and the size of n is determined by the radius r of the black point , An exemplary n=3×r, the value range of m can be diversified, usually 1 or 0. In other embodiments, the candidate candidate area is implemented as including three candidate positioning points forming an approximate right triangle, and the fourth point can be calculated through the three positioning points. The calculation method can be implemented with reference to the prior art (exemplary). In QR Code, 3 "回" fonts are used as anchor points, and the position of the fourth point is calculated through these 3 "回" fonts). The candidate area can be identified through the candidate positioning point, and the candidate area has no obvious recognition pattern. For example, in the prior art, QR Code has an obvious "back" character pattern, Maxi Code has an obvious bull's eye pattern, and DataMatrix has an obvious pattern. The two straight lines make the security of anti-counterfeiting higher.

The identification module of the anti-counterfeiting system of this embodiment includes a first identification unit 101 and a second identification unit 102. The first identification unit 101 is used to identify the anti-counterfeiting code set on the terminal device, including first obtaining one or more candidate identifications. Area, the effective identification area of the anti-counterfeiting code is located from the candidate identification area through the error correction code that comes with the anti-counterfeiting code (that is, the second identification information in the anti-counterfeiting code is used for error correction and verification, so as to perform the obtained candidate identification area Distinguish to determine the effective identification area), and obtain identification information from the effective identification area after the effective identification area is determined (that is, read the first identification information and the second identification information in the effective identification area to obtain the first identification information And the identification information of the second identification information). The second identification unit 102 is used to obtain the anti-counterfeiting information based on the identification information of the effective identification area and the relationship between the identification information and the anti-counterfeiting area (see the description of the anti-counterfeiting code section above), realize the extraction of anti-counterfeiting information, and effectively identify the identification information of the area And the anti-counterfeiting information is output to the anti-counterfeiting module 2. The second identification unit 102 extracts the anti-counterfeiting information according to the positioning information and the color information in the identification information of the anti-counterfeiting code, thereby achieving the acquisition of the anti-counterfeiting information based on the identification information. Obtaining anti-counterfeiting information through the positioning information and color information in the identification information can be specifically realized as: obtaining the spatial arrangement structure of the anti-counterfeiting area and the identification area through the positioning information. The exemplary anti-counterfeiting area is inside the identification area, that is, the anti-counterfeiting information is in the identification information. The inside of the anti-counterfeiting area; then through the mapping relationship between the color information in the identification information and the anti-counterfeiting area, the anti-counterfeiting area is obtained using color information, and then the anti-counterfeiting area is extracted according to the determined color information. Illustratively, the color information of the anti-counterfeiting area is White- Black, the color information includes black and white color blocks. If a color block in the anti-counterfeiting area is black, it is represented by 1, and if a certain color block is white, it is represented by 0, thereby obtaining binary anti-counterfeiting information.

Among them, the anti-counterfeiting module 2 includes an authenticating unit 201 and a verification unit 202. The authenticating unit 201 is used to perform a decoding operation to obtain anti-counterfeiting data according to the obtained anti-counterfeiting information and the identification information of the effective identification area, which is specifically implemented as follows: according to the code in the identification information The version information auxiliary anti-counterfeiting module 2 decodes the anti-counterfeiting information, that is, through the anti-counterfeiting area coding method and the anti-counterfeiting area code version. The decoding rules and methods have been reflected in the anti-counterfeiting area coding method and the anti-counterfeiting area code version in the identification information. The encoding method and encoding version information can be decoded according to the agreed protocol, and the anti-counterfeiting data can be obtained after decoding. Among them, the encoding method is expandable. Specifically, when writing the encoding method of the anti-counterfeiting code, multiple encoding methods will be written at the same time. After the current encoding method has a problem, it will be written into other encoding methods. Replacement, exemplarily, for the anti-counterfeiting code of version 2019-4-3, three encoding methods are provided when writing (the codes of these three encoding methods are 0, 1, 2). In the

current encoding method

0, 1 , 2 After a problem occurs, a new encoding method code 3 will be added, and the old encoding method is no longer used, and the new encoding method 3 is used for the newly generated anti-counterfeiting code through this encoding method. In this way, when it is judged that some encoding methods have been cracked or code leaked (for example, prediction is based on whether the number of times the encoding method has been authenticated exceeds the set identification threshold), a new encoding method is added to generate new encoding version information, and according to the new The encoding version information generates a new anti-counterfeiting code, and the old insecure encoding method is no longer used. The verification unit 202 is used for verifying the anti-counterfeiting data, generating an output of the authentication result, and then returning the result to the identification module 1, wherein the authentication data is obtained after the authentication data is verified based on the selected verification method (which can be implemented with reference to the prior art) The result of authentication is realized as a serial number. For example, for an anti-counterfeit code that converts an image into digital information (such as White-Black color space, black is converted to 1, white is converted to 0), according to the code of the security code According to the rules provided by the method, the position of these digital information is rearranged, and the rearranged information is decrypted according to the encoded version information of the anti-counterfeiting area (for example, the existing DES algorithm, RSA algorithm), and finally a serial number is generated . The serial number corresponding to the anti-counterfeiting code will be pre-stored in the anti-counterfeiting module (or pre-stored in the remote device where the anti-counterfeiting module is located, which can be accessed by the anti-counterfeiting module). If the anti-counterfeiting module is in the process of authenticating, it is judged according to the verification result The serial number is not detected, or the number of times the serial number has been authenticated has exceeded the threshold (the constraint conditions may not be set, and only the serial number is detected, which can be implemented flexibly according to requirements), then the output authentication result is Failure; if the anti-counterfeiting module detects the serial number during the authentication process, and the number of times the serial number has been authenticated does not exceed the threshold, the output authentication result is successful, and the output will be associated with the serial number The pictures, descriptions of the items, etc. (the serial number and its corresponding related information can be set and pre-stored when setting the coding rules corresponding to the anti-counterfeiting information).

In a preferred embodiment, as shown in FIG. 2, the anti-counterfeiting module further includes a counting unit 203, which is used to count the current times of authentication based on the authentication result, and make a judgment every time the identification module initiates an authentication request to the anti-counterfeiting module. After each authentication is successful, the anti-counterfeiting module 2 will record the authentication times of the serial number. When it is judged that the authentication of the anti-counterfeiting code reaches the preset authentication times threshold, the warning information output is generated, and the warning information can be realized as specific text or graphic information to indicate that the code may be forged.

According to the anti-counterfeiting system provided in this embodiment, the security factor of the anti-counterfeiting process of the anti-counterfeiting code can be effectively improved, and the difficulty of being cracked is increased by the identification and anti-counterfeiting modules provided at both ends.

FIG. 6 schematically shows a flow chart of an anti-counterfeiting method according to an embodiment of the present invention. As shown in FIG. 6, this embodiment includes the following steps:

Step S601: receiving identification information and anti-counterfeiting information. Among them, the identification information and anti-counterfeiting information are obtained from the anti-counterfeiting code set on the terminal device. The specific acquisition method: first obtain one or more candidate identification areas, and locate the effective identification area of the anti-counterfeiting code from the candidate identification area through the error correction code that comes with the anti-counterfeiting code (that is, correcting by the second identification information in the anti-counterfeiting code) Wrong sum check, so as to distinguish the obtained candidate identification areas to determine the effective identification area), and after the effective identification area is determined, the identification information is obtained from the effective identification area (that is, the first identification information in the effective identification area is read And second identification information to obtain identification information including the first identification information and the second identification information). The second identification unit 102 is used to obtain anti-counterfeiting information based on the identification information of the effective identification area, according to the relationship between the identification information and the anti-counterfeiting area (see the description of the anti-counterfeiting code section above), and output the identification information and anti-counterfeiting information of the effective identification area to the anti-counterfeiting information Module 2. The second identification module 102 decodes the anti-counterfeiting area encoding method and the anti-counterfeiting area code version of the anti-counterfeiting code to obtain the anti-counterfeiting information.

Step S602: Perform authentication processing according to the received identification information and anti-counterfeiting information, and generate an authentication result output. Among them, the specific authentication processing includes: the authentication result obtained after verifying the authentication data based on the selected authentication method (which can be implemented with reference to the prior art) is realized as a serial number, if the authentication is performed in the anti-counterfeiting module If the serial number is not detected, or the number of times the serial number has been authenticated has exceeded the threshold (the constraint condition may not be set, and only the serial number is detected, which can be implemented flexibly according to requirements), then the output authentication The result is a failure; if the anti-counterfeiting module detects the serial number during the authentication process, and the number of times the serial number has been authenticated does not exceed the threshold, the output authentication result is successful, and the serial number will be output The picture and description of the item associated with the number (the serial number and its corresponding associated information can be set and pre-stored when setting the coding rule corresponding to the anti-counterfeiting information). Then output the authentication structure to the terminal device.

In a preferred embodiment, the method further includes the following steps: setting a threshold for the number of times of authentication, and counting the current number of times of authentication based on the results of authentication, each time the identification module initiates an authentication request to the anti-counterfeiting module, each time after the authentication is successful , The anti-counterfeiting module 2 will record the identification times of the serial number. The number of times of forgery is judged, and when it is judged that the authentication of the anti-counterfeiting code reaches the threshold of the number of times of authentication, an early warning information output is generated. The early warning information can be realized as specific text or graphic information to indicate that the code may be forged.

The anti-counterfeiting method according to the present embodiment can identify and authenticate the counterfeit at both ends, so that the security factor of the anti-counterfeiting code in the authentication process is higher, and the anti-counterfeiting effect of the entire anti-counterfeiting code will not be invalidated because the single-end is cracked. Moreover, since the anti-counterfeiting code includes both identification information and anti-counterfeiting information, the identification of the identification information is realized through one end (which can be the identification module set in the terminal device), and the authentication of the anti-counterfeiting information is through the other end (which can be It is implemented by setting up the authentication module on the remote device (such as the cloud server). Therefore, when the anti-counterfeiting program is upgraded, only the cloud server needs to be upgraded. There is no need to upgrade various terminal devices or devices with anti-counterfeiting codes. The upgrade is more convenient and feasible.

What has been described above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, and these all fall within the protection scope of the present invention.
