Mobile phone biological identity certification production and authentication method, and its authentication system

Abstract

A biologic character template of a user and the related information of the user's identity constitute a whole data block, comprising: selecting an asymmetric key algorithm, using the private key to perform the digital signature or the digital seal, manufacturing the biologic character ID digital file of the digital signature, which is stored in the mobile phone of the user. The biologic character data of the user to be validated is collected on the site, and the digital certiuficate including the public key is sent to the user; mobile phone for storing the biologic character ID digital file in advance for verification; the mobile phone of the user uses the public key in the digital certificate to validate the digital signature of the biologic character ID digital file; the biologic character data to be certificated are inputted, to compare with the corresponding biologic character template in the biologic character ID digital file; the mobile phone of the user outputs the result data of the comparing and the validate, to display the result or output the authorization data of the further operation.

Description

technical field [0001] The invention generally belongs to the category of information encryption and authentication technology, and relates to a mobile phone biological identity certificate production method, an authentication method and a mobile phone biological identity certificate authentication system including biometric data. Background technique [0002] Identity proof and authentication are basic needs in social interaction activities. Currently, the identification and authentication of ID cards, passports, visas, work permits, access cards, bank cards, membership cards, etc. based on biometrics either use the mode of centralized comparison of biometric template libraries, or use biometric templates stored in IC cards. way, or a combination of both. [0003] With the increasing popularity of mobile phones in people's daily life and the increasingly powerful hardware functions, the functions of identity verification and authentication should be integrated in mobile ph...

AI Technical Summary

Problems solved by technology

[0003] With the increasing popularity of mobile phones in people's daily life and the increasingly powerful hardware functions, the functions of identity verification and authentication should be integrated in mobile phones, and the digital processing resources and capabilities of mobile phones can be used to play the functions of identity verification and identity verification. Avoid the privacy violation caused by the centralized biometric template library, and the situation that the biometric templates are stored in different IC cards and cannot be compatible with IC card readers
