System for face authentication and method for face authentication

A face authentication server device used for performing a face authentication process for determining whether or not a person to be verified is a registered user based on face image data acquired by imaging the person to be verified,

• wherein the face authentication server device is connected to a plurality of face authentication machines via a network, each face authentication machine comprising a camera for imaging persons to be verified,
• wherein the face authentication server device further comprises:
• a face management server configured such that, when face image data of users is registered, the face management server stores and accumulates face image data of each user in association with a matching group corresponding to an organization to which the user belongs;
• and
• a plurality of face matching servers, each face matching server including a face matching database and being configured such that, when receiving a request for registration of a user from the face management server, each face matching server generates face feature amount data from face image data of the user, and registers the generated face feature amount data in association with the matching group in the face matching database,
• when acquiring the face image data of the person to be verified from one of the plurality of face authentication machines, each face matching server performs a matching operation between face feature amount data of registered users stored separately for respective matching groups and face feature amount data generated from the face image data of the person to be verified, and
• when face feature amount data of a plurality of registered users belonging to a same matching group is to be registered in two or more face matching databases and associated with the same matching group and the two or more of the face matching databases include a first matching database and a second matching database which are included in a first face matching server and a second face matching server, respectively, upon receiving a request for registration of the plurality of registered users, the first face matching server registers the face feature amount data of the plurality of registered users in the first face matching database, and upon receiving a transfer instruction from the face management server, the first face matching server copies and transfers the face feature amount data of the plurality of registered users in batch from the first face matching database to the second face matching server, and in response, the second face matching server registers the transferred face feature amount data in the second face matching database thereby enabling registration of the face feature amount data in two or more face matching servers.

A method for registration of face feature amount data, the method being performed by a server device configured to perform a face authentication process based on face image data acquired by imaging a person to be verified,

• the server device including a face management server and a plurality of face matching servers, and being connected to one or more face authentication machines, each face matching server including a face matching database, each face authentication machine comprising a camera for imaging persons to be verified,
• the method comprising:
• storing and accumulating, by the face management server, face image data of each user in association with a matching group corresponding to an organization to which the user belongs;
• and
• generating, upon receiving a request for registration of a user from the face management server, by each face matching server, face feature amount data from face image data of the user, and registering the generated face feature amount data in association with the matching group in the face matching database,
• upon acquiring the face image data of the person to be verified from one of the plurality of face authentication machines, each face matching server performs a matching operation between face feature amount data of registered users stored separately for respective matching groups and face feature amount data generated from the face image data of the person to be verified, and,
• when face feature amount data of a registered user is to be registered in two or more face matching databases and associated with a same matching group as the registered user and the two or more of the face matching databases include a first matching database and a second matching database which are included in a first face matching server and a second face matching server, respectively, upon receiving a request for registration of the registered user, the first face matching server registers the face feature amount data of the registered user in the first face matching database, and, upon receiving a transfer instruction from the face management server, the first face matching server copies and transfers the face feature amount data of the registered user from the first face matching database to the second face matching server, and in response, the second face matching server registers the transferred face feature amount data in the second face matching database thereby enabling registration of the face feature amount data in two or more face matching servers.
