Abstract
Unauthorized use of a biological pattern registered in a face image authorization system is made difficult. With respect to the previously registered biological pattern for authorization, additional information is held concerning a change that can be reproduced by a user having the biological pattern for authentication, and success or failure of the authentication is evaluated according to consistency between the biological pattern for authentication that is reproduced using the additional information and a pattern input at the time of authentication as an evaluation factor. By changing the additional information as necessary, unauthorized use of biological pattern data or the like is made difficult.
Claims19
An authentication apparatus that,
- with respect to a previously registered biological pattern for authentication, holds additional information concerning a change that can be reproduced by a user having the biological pattern for authentication, and
- evaluates success or failure of authentication according to consistency between the biological pattern for authentication that is reproduced using the additional information and a pattern input at authentication time as an evaluation factor.
An authentication method comprising:
- with respect to a previously registered biological pattern for authentication, holding additional information concerning a change that can be reproduced by a user having the biological pattern for authentication;
- and
- evaluating success or failure of authentication according to consistency between the biological pattern for authentication reproduced using the additional information and a pattern input at authentication time as an evaluation factor.
A storage medium that stores a program for causing a computer to execute:
- with respect to a previously registered biological pattern for authentication, a process to receive an input of additional information concerning a change that can be reproduced by a user having the biological pattern for authentication;
- and
- a process to evaluate success or failure of authentication according to consistency between the biological pattern for authentication reproduced using the additional information and a pattern input at authentication time as an evaluation factor.
