Identity verification method and device based on biological characteristics and client

Abstract

The invention discloses an identity authentication method and device based on biological characteristics and a client. The method comprises the following steps: acquiring biological characteristic information of a target user; carrying out first comparison on stored biological characteristic reference data and the biological characteristic information; if the first comparison judges that no matched biological characteristic reference data exists, determining that the identity verification of the target user fails; if the matched biological characteristic reference data is judged to exist in the first comparison, sending the biological characteristic information to a server for second comparison; and determining whether the target user is successfully authenticated or not according to the second comparison result fed back by the server. According to the method, the overall security of the system can be improved, the identity authentication failure of the target user can be determined atthe client, a large amount of biological characteristic information can be prevented from being sent to the server for second comparison, and the successful result of identity authentication cannot be influenced even if mismatching occurs during first comparison.

Description

【Technical field】 [0001] The present invention relates to the technical field of identity verification, in particular to an identity verification method, device and client based on biological features. 【Background technique】 [0002] Biometric identification refers to the use of automatic technology for identification to extract individual physiological characteristics or personal behavior characteristics, and compare these characteristics or characteristics with existing biometric reference data to complete the identification process. [0003] Biometric identification technology has been more and more widely used. In one embodiment, when the service or data to be accessed is located at the remote server end of the network, before obtaining access authorization, the client directly sends the biometric information to the server , the server performs biometric identification on the biometric information to determine whether to authorize the client to access data or services. ...

AI Technical Summary

Problems solved by technology

[0005] In the first aspect, when the server performs biometric identification on the received biometric information, the server will compare the biometric reference data stored on the server with the biometric information one by one. When the number of registered users on the server is large , that is, when the server stores a large number of biometric reference data of registered users, comparing them one by one will greatly increase the performance consumption of the server, resulting in low recognition efficiency

[0006] In the second aspect, because the client sends the biometric information to the server, and then the server performs biometric identification, therefore, there may be a long time between the client sending the biometric information and waiting for the identification result of the server. Response time affects user experience

[0007] In the third aspect, the security of a single biometric identification is not enough, and it is easy to crack through camouflage and other means
