摘要：
A biometric authentication apparatus for identifying a subject person by using biometric information of a user has memories and a processing unit for performing biometric authentication. The memories and store a remaining trial number whose value is reduced each time biometric authentication fails. The processing unit generates a lower limit value smaller than the remaining trial number at the start of biometric authentication, performs biometric authentication until the reduced remaining trial number becomes equal to or smaller than the lower limit value, and generate alarm data for issuing alarm to the user when the reduced trial number becomes equal to or smaller than the lower limit value.
