<p>Provided are a biometric authentication system which can guarantee an FMR in a practical processing time even when an attacker attacks the biometric authentication system by selectively using query data in which data of a set other than a biometric information data set is included, a biometric authentication method, and a biometric authentication program. The biometric authentication system of the present invention is characterized by including rating value calculation means 5 for calculating a probability that input data randomly matches given data and taking it as a rating value; and determination means 6 for determining whether or not the input data is identified as template data indicating biometric information stored in advance based on the rating value calculated by the rating value calculation means 5.</p> |
