    • The present invention relates to improving the identification rate for a person without lowering the rate of excluding another person probabilistically. The invention is a personal identification system that finds the verification results of feature data extracted form data showing the physical features of the individual who is the verification source against the pre-registered feature data of the verification object, and identifies the individual by whether or not the degree of similarity obtained by the verification results exceeds a separate threshold value set according to pre-registered feature data, and wherein a separate threshold value calculation device 23 is provided that calculates the separate threshold value based on the verification score distribution of feature data extracted from data showing the physical features of the individual who is the verification source and the corresponding feature data, and the verification score distribution of the feature data extracted from data showing the physical features of the individual who is the verification source and non-corresponding feature data.
    • 本发明涉及提高人的识别率,而不降低概率排除另一人的速度。 本发明是一种个人识别系统,其根据验证对象的预先注册的特征数据,找出提取的表格数据的特征数据的验证结果,其显示作为验证源的个体的身体特征,并且通过是否对该个体进行识别 通过验证结果获得的相似度超过根据预先注册的特征数据设置的单独阈值,并且提供单独的阈值计算装置23,其基于提取的特征数据的验证分数分布来计算单独的阈值 从显示作为验证源的个体的物理特征的数据和相应的特征数据,以及从表示作为验证源的个体的物理特征的数据和非对应的特征数据提取的特征数据的验证分数分布 。
