Abstract

A system performing secondary verification using only existing apparatuses to accomplish a measure for relief in personal authentication without causing complexity or without increasing cost. The system has a registering apparatus for obtaining data for verification from information inputted using an inputting unit and registering the data. The registering apparatus has a first extracting unit for extracting biometrics characteristic data from the biometrics information obtained by the inputting unit, and registering the biometrics characteristic data as registry biometrics characteristic data for primary verification, and a second extracting unit for extracting data, which is different from the registry biometrics characteristic data, from information inputted using the inputting unit and registering the data as registry data for secondary verification. The system is used for personal authentication using biometrics information such as fingerprint, palm print, finger shape, palm shape, voice, retina, iris, face image, dynamic signature, blood vessel pattern, keystroke, or the like.
