BIOMETRIC CERTIFICATES

摘要

A biometric certification system includes a biometric certificates extractor system (64) for extracting biometric certificates (68) which may be used for authentication in any electronic transaction having biometric database (66) for pre-storing the obtained biometric data corresponding to physical characteristics of registered users throughout a biometric input device. Subsequent transaction to be conducted over the network (60) have digital signatures (58) generated from the physical characteristics of a current user and from the electronic transaction. The electronic transaction is authenticated by comparing the hash values in the digital signature with recreated hash values. The user is authenticated by comparison against the prestored biometric certificates of the physical characteristics of the users in the biometric database.
