[0025] Embodiment 1

[0026] According to an embodiment of the present invention, an embodiment of a face authentication and recognition method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0027] Figure 1 It is a flowchart of the face authentication and recognition method according to an embodiment of the present invention. As Figure 1 shown, the method includes the following steps:

[0028] Step S102, when it is detected that the user performs face registration, obtain the face feature information of the above user and the 3D code style selected by the above user;

[0029] Step S104, determine the encryption key and encryption algorithm corresponding to the above three-dimensional code style;

[0030] Step S106, perform an encryption operation on the above face feature information by using the above encryption key and the above encryption algorithm to generate face feature point ciphertext;

[0031] Step S108, generate the face authentication three-dimensional code of the above user by using the above face feature point ciphertext and three-dimensional code image information, wherein the above three-dimensional code image information is determined according to the above three-dimensional code style by using a three-dimensional code generation algorithm.

[0032] In the embodiment of the present invention, the execution subject of the face authentication and recognition solution provided in the above steps S102 to S108 is a server. That is, when a user registers for a face authentication and recognition service, the server is used to obtain the face feature information of the above user and the three-dimensional code style selected by the above user, perform an encryption operation on the above face feature information by using the encryption key and encryption algorithm corresponding to the above three-dimensional code style, calculate the face feature point ciphertext, and combine the above face feature point ciphertext with the three-dimensional code image information to generate the face authentication three-dimensional code of the above user.

[0033] It should be noted that when the above user performs face registration, various types of intelligent devices can be used for registration, such as: smart phones, smart computers, etc.; the above three-dimensional code style can be selected according to the user's preference, and can include: displaying / not displaying the face, any background image, special three-dimensional code shape, etc.; the above three-dimensional code image information is determined according to the above three-dimensional code style by using a three-dimensional code generation algorithm; the advantage of the above three-dimensional code compared with the two-dimensional code is that: the three-dimensional code has a larger information capacity, can encode complex face feature information, and also has a built-in anti-counterfeiting function.

[0034] As an alternative embodiment, as Figure 2 shown in the schematic diagram of the three-dimensional code generation process, before generating the three-dimensional code, first, the user needs to perform face registration. After the server detects the user's face information, the feature vector of the face feature points is obtained; at the same time, the three-dimensional code style selected by the user is obtained. The server generates the corresponding encryption key and encryption algorithm according to the style selected by the user, and uses the encryption key and the corresponding encryption algorithm to perform an encryption operation on the face feature points to generate face feature point ciphertext. Finally, the face feature information is saved on the three-dimensional code in the form of ciphertext for the user to save by himself, without having to worry about the problem of data leakage on the server side.

[0035] It should be noted that the encryption algorithm and key used for encryption correspond to the format of the three-dimensional code. The key and algorithm are both stored on the server side. After the facial feature information is encrypted, it is saved on the three-dimensional code. The above encryption algorithm and key do not need to be transmitted to the user and are only stored on the server side. When decrypting, the server can determine the format of the three-dimensional code by intelligently identifying the three-dimensional code image, and then find the corresponding decryption algorithm and key on the server side to decrypt the facial feature information and perform authentication.

[0036] Through the embodiments of the present invention, the facial feature information is encrypted and saved in the three-dimensional code. The user can generate and save their own three-dimensional code, without worrying about problems such as leakage, loss, and damage. When the user needs to perform facial authentication, the user can complete the identity authentication through facial recognition and three-dimensional code verification, achieving the purpose of saving the facial feature information in the form of ciphertext of feature points on the three-dimensional code, thus realizing the technical effect of completing facial authentication using the three-dimensional code, and further solving the technical problem of the risk of leakage of the user's facial information in the existing facial authentication recognition method.

[0037] In an optional embodiment, generating the above-mentioned facial authentication three-dimensional code of the user by using the above-mentioned ciphertext of facial feature points and three-dimensional code image information includes:

[0038] Step S202: Compile the above-mentioned ciphertext of facial feature points into binary digits;

[0039] Step S204: Use the three-dimensional code generation algorithm to determine the above-mentioned three-dimensional code image information according to the above-mentioned three-dimensional code style;

[0040] Step S206: Perform sequence coding processing on the above-mentioned binary digit string and the above-mentioned three-dimensional code image information to obtain the above-mentioned facial authentication three-dimensional code.

[0041] In the embodiments of the present invention, the server compiles the above-mentioned ciphertext of facial feature points into binary digits, and uses the three-dimensional code generation algorithm to determine the above-mentioned three-dimensional code image information according to the above-mentioned three-dimensional code style; performs sequence coding processing on the above-mentioned binary digit string and the above-mentioned three-dimensional code image information to obtain the above-mentioned facial authentication three-dimensional code.

[0042] It should be noted that the above-mentioned three-dimensional code image information can be determined according to the user's selection results (which can include: showing / hiding the face, any background image, special three-dimensional code shape, etc.).

[0043] As an alternative embodiment, the server compiles the ciphertext of the feature points into a string of binary digits, and then, through a specific three-dimensional code generation algorithm and in combination with the overall color content of the generated picture of the three-dimensional code style, encodes the binary digit string and the image information into an array that can be interpreted through specific rules, namely the three-dimensional face authentication code; the above three-dimensional code can be printed in color or sent as an electronic photo to the user's electronic storage device for easy carrying and preservation by the user.

[0044] It should be noted that when performing face registration, the face image is mapped into a 128-dimensional feature vector, the AES encryption algorithm is used, a 128-bit encryption key is adopted, and different three-dimensional code styles correspond to different encryption keys.

[0045] In an alternative embodiment, after generating the three-dimensional face authentication code of the above user by using the above ciphertext of the face feature points and the three-dimensional code image information, the above method further includes:

[0046] Step S302, when detecting that the above user performs face authentication, scan the above three-dimensional face authentication code to obtain the above ciphertext of the face feature points;

[0047] Step S304, use an intelligent image recognition algorithm to recognize the three-dimensional code image information of the above three-dimensional face authentication code to obtain the above three-dimensional code style;

[0048] Step S306, determine the decryption key and decryption algorithm corresponding to the above three-dimensional code style;

[0049] Step S308, perform a decryption operation on the above ciphertext of the face feature points by using the above decryption key and the above decryption algorithm to obtain the above face feature information.

[0050] In the embodiment of the present invention, as Figure 3 shown in the schematic diagram of the face authentication process, when detecting that the above user performs face authentication, the server scans the above three-dimensional face authentication code to obtain the above ciphertext of the face feature points; uses an intelligent image recognition algorithm to recognize the three-dimensional code image information of the above three-dimensional face authentication code to obtain the above three-dimensional code style; performs a decryption operation on the above ciphertext of the face feature points by using the above decryption key and the above decryption algorithm to obtain the above face feature information.

[0051] As an alternative embodiment, during face authentication, the face feature point matching algorithm selects the Euclidean distance. The smaller the Euclidean distance, the greater the similarity and the more likely it is the face information of the same person.

[0052] In an alternative embodiment, after performing a decryption operation on the above ciphertext of the face feature points by using the above decryption key and the above decryption algorithm to obtain the above face feature information, the above method further includes:

[0053] Step S402: Perform face detection on the above user to obtain the current face feature information of the above user;

[0054] Step S404: Perform feature matching operation on the above current face feature information and the above face feature information to obtain the face similarity degree;

[0055] Step S406: Determine the face authentication result of the above user according to the comparison result between the above face similarity degree and a preset threshold.

[0056] In an embodiment of the present invention, when a user performs face authentication, the server is used to perform face detection on the above user to obtain the current face feature information of the above user; perform feature matching operation on the above current face feature information and the above face feature information to obtain the face similarity degree; and determine the face authentication result of the above user according to the comparison result between the above face similarity degree and a preset threshold.

[0057] It should be noted that the above face feature matching operation determines the face similarity according to the calculated Euclidean distance. The smaller the Euclidean distance, the greater the similarity.

[0058] In an alternative embodiment, determining the face authentication result of the above user according to the comparison result between the above face similarity degree and a preset threshold includes:

[0059] Step S502: If the above comparison result is that the above face similarity degree is greater than or equal to the above preset threshold, then determine that the above face authentication result is face authentication successful;

[0060] Step S504: If the above comparison result is that the above face similarity degree is less than the above preset threshold, then determine that the above face authentication result is the above face authentication failed.

[0061] In an embodiment of the present invention, when the above similarity is greater than the preset threshold, it is determined that the authenticated user and the registered user are the same user, that is, the above face authentication result is face authentication successful; when the above similarity is less than the preset threshold, it is determined that the authenticated user and the registered user are different users, that is, the above face authentication result is face authentication failed.

[0062] As an alternative embodiment, as Figure 4 shown in the schematic diagram of the face authentication process structure, when a user performs face authentication, the user provides a face authentication three-dimensional code to the authentication device for scanning. After the above device reads the ciphertext, it uses an intelligent image recognition algorithm to recognize the overall color content of the scanned three-dimensional code picture to obtain the style of the three-dimensional code. The above server finds the corresponding decryption key string code and decryption algorithm through the style of the three-dimensional code, and uses the key string code and the corresponding decryption algorithm to decrypt the ciphertext to obtain the registered face feature information.

[0063] Optionally, the server performs face detection on the user, obtains the facial feature point information to be authenticated, and performs feature matching operations with the registered facial feature point information. The closer the feature distance is, the more likely it indicates the same user; otherwise, it is a different user, obtaining the authentication result and completing the entire process of face authentication.

[0064] It should be noted that the above three-dimensional code enriches the overall color content of the picture, and users can also obtain some or even all of the image information by simply using the human eye to identify; the above server can train various styles of three-dimensional codes in large quantities, enabling the intelligent image recognition algorithm to accurately identify various three-dimensional code styles and improving the authentication speed and authentication ability.

[0065] Through the above steps, it is possible to save the facial feature information in the form of ciphertext on the three-dimensional code. Utilizing the larger information capacity of the three-dimensional code, complex facial feature information can be encoded, with a built-in anti-counterfeiting function, achieving the purpose of saving the facial feature information in the form of feature point ciphertext on the three-dimensional code, thereby realizing the technical effect of completing face authentication using the three-dimensional code, and further solving the technical problem of the risk of leakage of users' facial information in the existing face authentication and recognition methods.
