Abstract

According to one embodiment, a person authentication method includes obtaining, from a medium carried by a person who passes through a first position, first information indicating the gender and the age of the person; performing a first authentication operation with respect to a person whose face image is included in a first image obtained by capturing a person passing through the first position; and setting, as the first authentication operation, an authentication operation to be performed using the face image of a person having the gender and the age specified in the first information.

First claim

What is claimed is:

1. A person authentication method comprising:
obtaining, from a medium carried by a person who passes through a first position, first information indicating gender and age of the person;
performing a first authentication operation with respect to a person whose face image is included in a first image obtained by capturing a person passing through the first position;
setting, as the first authentication operation, an authentication operation to be performed using a face image of a person having gender and age specified in the first information;
storing history information of the first authentication operation in a corresponding manner to first identification information of a person who is successfully authenticated in the first authentication operation,
obtaining, from a medium carried by a person who passes through a second position at downstream side of the first position in direction of traffic of persons, second identification information of the person,
performing a re-authentication operation with respect to a person with face image included in a second image that is taken by capturing a person passing through the second position,
retrieving, from the first memory, the history information matching with a predetermined reconfirmation history condition, and
performing the re-authentication operation only when the second identification information matches with the first identification information that is stored in a corresponding manner to the retrieved history information.

2. The person authentication method according to claim 1 , wherein
detecting a factor causing abnormality in the first image, and
setting, as the first authentication operation, an authentication operation to be performed using a face image having same factor causing abnormality as the detected factor causing abnormality.

3. The person authentication method according to claim 1 , further comprising
detecting fraudulent behavior of a person passing through the first position, and
storing, in a second memory unit, the first information that is obtained when fraudulent behavior of a person passing through the first position is detected.

4. The person authentication method according to claim 2 , further comprising displaying, on a display, a message instructing elimination of the detected factor causing abnormality.
