Embodiment Construction

[0048] The present application will be described in detail below in conjunction with the accompanying drawings, and the specific operation methods in the method embodiments can also be applied to the device embodiments.

[0049] figure 1 An exemplary flow chart corresponding to an identity authentication method provided by an embodiment of the present invention is shown, as shown in figure 1 shown, including the following steps:

[0050] Step 101, acquire the physical sign data of the user to be authenticated and the face data of the user to be authenticated.

[0051] Step 102: Determine at least one candidate user from the multiple authenticated users according to the physical sign data of the user to be authenticated and the pre-stored physical sign data of multiple authenticated users.

[0052] Step 103, using a preset feature extraction model to extract features corresponding to the face data of the user to be authenticated, and obtaining a feature vector corresponding to ...

Abstract

The invention discloses an identity authentication method and device. The method comprises the following steps of: obtaining sign data and face data of a to-be-authenticated user; according to the physical sign data of the to-be-authenticated user and pre-stored physical sign data of a plurality of authenticated users, and determining a candidate user according to the extracted feature vector corresponding to the to-be-authenticated user and the extracted feature vector corresponding to the candidate user, and determining that the to-be-authenticated user passes identity authentication after determining that similar users exist in the candidate users. Therefore, the similar users only need to be determined from the candidate users, and the number of the candidate users is far smaller thanthe number of the pre-stored authenticated users, so that the identity authentication method provided by the embodiment of the invention can greatly shorten the identity authentication time and improve the working efficiency of the identity authentication system.

Description

technical field [0001] The invention relates to the field of face recognition, in particular to an identity authentication method and device. Background technique [0002] At present, biometric identification technology is widely used in the security field and is one of the main means of authenticating user identities. Biometric identification technology, especially face recognition technology, has been widely used in various fields, such as financial payment field, access control security field and so on. In view of the advantages of convenience, user-friendliness, and non-contact, face recognition technology has achieved rapid development in recent years. [0003] However, the traditional face recognition technology needs to compare the user to be authenticated with each sample in the sample database. As the sample size in the sample database continues to expand, the time and energy spent on authenticating the user to be authenticated will inevitably increase. increase, ...
