Title: Biometric authentication device and method, computer-readable recording medium recorded with biometric authentication computer program, and computer system

Abstract: A computer system checks whether or not an authentication success rate for a registered user shows an over-time reduction based on the history of the results of the previous biometric authentication processes in which the high-speed verification process is executed, when the authentication success rate is determined as showing an over-time reduction for the registered user, the computer system instead executes a precise verification process for verifying input biometric information against registered biometric information to make verification with a higher precision than with the high-speed verification process.
