SYSTEM, APPARATUS, AND METHOD FOR BIOMETRIC AUTHENTICATION

PROBLEM TO BE SOLVED: To provide a biometric authentication system which has a self authentication module for performing an in-device authentication process and is capable of preventing personal information theft, falsification of internally stored biometric data, and counterfeiting of the module.SOLUTION: A biometric authentication system having a biometric authentication module and a host device, which are interconnected to communicate to each other, defines a communication protocol between the host and the module and operates based on a response to a predefined command. Registration of a template of a user who goes through an authentication process with biometric data is done under supervision of a supervisor, and is carried out by sending a hash value for the template to the host side. The host side gives a digital signature to the hash value, sends data associated with the signature to the biometric authentication module, and stores the same together with the template. Verification of data in the module is done from the host side using the challenge and response mechanism, and authentication results can also be associated with each authentication request using the challenge and response mechanism.
