Inputted information (such as biometric information) is compared to template information (including correlation or authentication) and the result is recorded as log information. According to log information for each of the types of the inputted information (such as information specifying the user who has inputted it and the template), analysis is executed for the inputted information for each of the types. This analysis includes the following aspects. That is, the following states are detected and an alarm is outputted for the accuracy of the corresponding type: (1) when the ratio of negativecomparison results (correlation failures) not smaller than a predetermined value is detected within a predetermined period of time; and (2) when a negative result is detected within a predetermined time before an affirmative comparison result is obtained.
