Embodiment Construction

[0022] In general, the identity authentication method proposed cannot cope well with some situations including forgetting the key, the key is stolen, and the terminal with the password is lost. Information loss, even property loss and other problems, and the problem of poor security, in the technical solution proposed by the embodiment of the present invention, the user's identity is determined and the user's face information is collected through the authentication request sent by the user, and the After the collected facial information is subjected to illumination preprocessing, the first feature vector corresponding to the user is obtained. Based on the identity of the user in the correspondence between the pre-stored identity and the second feature vector, find the corresponding eigenvector corresponding to the identity. The second eigenvector, compare the first eigenvector and the second eigenvector, and finally complete the identity authentication of the user according to ...

Abstract

The invention discloses an identity authentication method and device. By means of the method and device, the problems of inaccessibility or data loss caused by password loss under normal conditions can be solved, and the security can be better improved. The method comprises the steps of receiving an authentication request sent by a user; obtaining an identity of the user from the authentication request sent by the user, and confirming facial information of the user based on a photographic device; after conducting illumination pretreatment to the obtained facial information, extracting local binary patterns (LBP), and obtaining a first feature vector corresponding to the facial information; with the obtained identity as an index, determining a second feature vector corresponding to the obtained identity in the corresponding relationship between the identity which is stored in advance and the second feature vector; comparing the first feature vector with the second feature vector; when a comparison result is greater than a first preset threshold value and smaller than a second preset threshold value, confirming that the identity of the user passes the authentication.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an identity authentication method and device. Background technique [0002] User identity authentication refers to completing the confirmation of the user's identity through certain means, and its purpose is to confirm that the user who currently claims to be a certain identity is indeed the claimed user. With the continuous development of communication technology, identity authentication is of great significance for protecting user privacy information. [0003] At present, there are many methods of identity verification, which can be basically divided into: identity authentication based on shared key, identity authentication based on biological characteristics and identity authentication based on public key encryption algorithm. Usually, the identity authentication based on the shared key is mainly used in the mobile terminal. The server and the user share a password or a set...
