Title:
１：Ｎ生体認証・暗号・署名システム
Document Type and Number:
Japanese Patent JP6507115
Kind Code:
B2
Abstract:
A biometric authentication system comprises a terminal comprising a feature extraction unit which extracts feature data for authentication from acquired biometric information, an encoding unit which encodes feature data for authentication, thus creating encoded feature data for authentication, and a transmitting unit which transmits encoded feature data for authentication; and a server comprising a DB for storing encrypted authentication information, a search unit which searches for encrypted authentication information included in the DB, a decryption unit which decrypts encrypted authentication information searched out using encoded feature data for authentication as a decryption key and uniquely identifies a user, based on authentication information obtained, and a processing unit which performs authentication response processing with respect to the identified user, based on authentication information obtained by decryption, instead of a user terminal. This system implements convenient and safe authentication without limiting user and terminal combinations, without reconfiguring a service server, and without requiring a user to enter an ID or present a card among others, when a user utilizes a variety of existing services from one or plural terminals.
