  • Biometric authentication system, communication terminal device, biometric authentication device, and biometric authentication method
    Patent number: 9049191
    Abstract: Provided is a biometric authentication system capable of preventing spoofing attacks even if leakage of key information and a registration conversion template occurs. A communication terminal device (300) calculates secret key information k? which is exclusive OR of key information k of the registration biological information and masked value c? which is randomly selected from a predetermined error correction code group, and calculates verified information c?? which is exclusive OR of sent information c? and value c?. A biometric authentication device (500) calculates exclusive OR of authentication biological information, information k?, and registration conversion template w, as information c?, wherein the template w is exclusive OR of information x, information k, and authentication parameter c randomly selected from the code group; and performs biometric authentication on the basis of a degree of matching between information c?? corresponding to information c?, and the parameter c.
