Identity authentication method, device and system

Abstract

The invention discloses an identity authentication method, device and system. The method includes the steps that legal authentication two-dimensional codes of authentication users are generated, face information of the authentication users is collected to generate legal face feature data of the users, legal personal mask codes of the authentication users are generated according to the legal face feature data, and the legal authentication two-dimensional codes and the legal personal mask codes are subjected to reversible operation to obtain encrypted two-dimensional codes; when the users are subjected to identity authentication, face information of the users is collected again to generate current face feature data, current personal mask codes are generated according to the current face feature data, the current personal mask codes and the encrypted two-dimensional codes are subjected to reversible operation to obtain two-dimensional codes to be authenticated, and whether the two-dimensional codes to be authenticated are consistent with the legal authentication two-dimensional codes is judged. The problem of user information leakage caused by storage of face recognition images is avoided, and the intensity and safety of identity authentication are improved.

Description

technical field [0001] The invention relates to the field of identity authentication, in particular to an identity authentication method, device and system. Background technique [0002] Face recognition, specifically refers to the computer technology that uses the analysis and comparison of facial visual feature information for identity identification. Face recognition is a series of related technologies that use cameras or cameras to collect images or video streams containing faces, and automatically detect and track faces in the images, and then perform facial recognition on detected faces, usually also called portrait recognition. ,face recognition. Face recognition technology is based on human facial features. For the input face image or video stream, it is first judged whether there is a human face. If there is a human face, the position, size and each main The location information of facial organs, and based on this information, further extract the identity features...

AI Technical Summary

Problems solved by technology

[0004] In the existing field of identity authentication, two-dimensional codes are generally used for identity authentication. The emphasis is on the efficiency and convenience of two-dimensional codes, while security is easily overlooked. Then criminals can use the two-dimensional codes as long as they obtain the two-dimensional codes. The two-dimensional code is forged to become a legitimate user, which damages the rights and interests of the legitimate user
