摘要：
A mobile information terminal includes a sample acquisition unit configured to acquire a sample, a sample transmission unit configured to transmit the sample and a user ID, an other's sample reception unit configured to receive other's samples, a user authentication template learning unit configured to learn a user authentication template and an authentication determination threshold value by using the other's samples and samples of the authentic user, and a template storage unit configured to store the user authentication template and the authentication determination threshold value, and a server includes a sample reception unit configured to receive a sample and a user ID, a clustering unit configured to classify the sample that is received into a feature cluster, a sample storage unit configured to store the sample that is classified, in association with the user ID, a feature cluster extraction unit configured to extract all samples which belong to a feature cluster identical to a feature cluster corresponding to the user ID that is received, and an other's sample transmission unit configured to transmit the samples that are extracted, as other's samples.
