<P>PROBLEM TO BE SOLVED: To prevent an illegal action performed by another user by combining authentication using an ID card with authentication utilizing features of a human body. <P>SOLUTION: A user carrying a wireless card 10 with an IC tag and a pressure sensor 0 presses the pressure sensor 0 to request authentication. Thus, an identification ID is transmitted to an authentication apparatus 20, and the authentication apparatus 20 reads feature information C corresponding to the identification ID from a storage area 30E. The authentication apparatus 20 then collates a feature amount from a face image of the user acquired by a camera 22 with the feature information C to perform authentication. Thus, if a regular user does not carry a wireless card 10, affirmative authentication can not be obtained, thereby improving an authentication accuracy. <P>COPYRIGHT: (C)2007,JPO&INPIT |
