    • 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: when the ratio of negative comparison results (correlation failures) not smaller than a predetermined value is detected within a predetermined period of time; and when a negative result is detected within a predetermined time before an affirmative comparison result is obtained.
    • 将输入信息(如生物特征信息)与模板信息(包括相关或认证)进行比较,并将结果记录为日志信息。 根据输入信息的每种类型(诸如指定输入的用户的信息和模板)的日志信息,针对每种类型的输入信息执行分析。 该分析包括以下几个方面。 也就是说,检测到以下状态并为相应类型的精度输出报警:当在预定时间段内检测到不小于预定值的负比较结果(相关故障)的比率时; 并且当在获得肯定比较结果之前的预定时间内检测到否定结果时。
