Authentication candidate extraction device, authentication system, authentication candidate extraction method and program

摘要

An object of the present invention is to achieve both protection of authentication data and ensuring response performance. The authentication candidate extraction device includes a biometric information input unit for inputting biometric information acquired at the first point for the subject to be authenticated moving from the first point to the second point, and an authentication process for the subject to be authenticated. A candidate for the feature information for the authentication process is selected by a predetermined secret calculation method using the feature information storage unit for storing the feature information for the purpose and the feature extracted from the biometric information acquired at the first point. A feature information transmission unit that transmits a candidate for the extracted feature information to an authentication device that performs authentication processing using the biometric information of the subject to be authenticated acquired at the second point. To be equipped with.
