Claim 7:
8. A verification server for verifying detection data acquired by a detection apparatus with registration data that has been registered in advance, wherein
the verification server has a main database for storing all the registration data, and another verification server is arranged closer to the detection apparatus than the verification server and has a sub-database for storing part of the registration data,
said another verification server is configured to analyze the detection data that has been acquired by the detection apparatus, verify the analyzed detection data with the registration data within the sub-database, determine that in the case where the matching degree which is calculated for the registration data that matches the detection data the most is no smaller than the first threshold value, the verification is successful, otherwise, the verification is failure, and transmit the detection data to the verification server for further verification in the case where the verification is a failure, and
said another verification server is further configured to transmit the detection data, in the case where the verification is successful and the matching degree is no greater than the second threshold value, with a verification result data indicating the verification is successful to the first verification server for storing as learning data in order to learn an inference model for data analysis,
the verification server is configured to analyze the detection data that has been received from said another verification server in the case where the verification is failure, verify the analyzed detection data with the registration data within the main database, determine that in the case where the matching degree which is calculated for the registration data that matches the detection data the most is no smaller than the first threshold value, the verification is successful, otherwise, the verification is failure, and transmit the verification results to the sub-verification server, and
the verification server if further configured to store detection data with a verification result data indicating the verification is successful as the learning data in the case where the matching degree, is no smaller than the first threshold value and no greater than the second threshold value, and store the detection data with the data on the results of the verification is failure as the learning data in the case where the matching degree is no greater than the first threshold value and no smaller than the third threshold value.
