4. A method for face authentication used for performing a face authentication process based on image data of a person to be verified, wherein the method is performed by a system for face authentication, the system including: a plurality of face authentication machines; a server device connected to the plurality of face authentication machines via a network; and a terminal device connected to the server device via the network, the method comprising:
upon registration of users, by the server device, storing and accumulating face image data of the users, wherein the face image data of each user is stored in association with one or more matching groups;
generating, from the face image data of the users, face feature amount data of the users, and registering the face feature amount data of each of the users in association with the one or more matching groups; and
performing the face authentication process, the performing comprising:
each of the face authentication machines shooting the person to be verified by a camera to generate image data of the person to be verified; and
the server device generating face feature amount data of the person to be verified from the image data shot by the camera, and performing a matching operation between the face feature amount data of the person to be verified and the face feature amount data of the users,
wherein the server device comprises a plurality of face image matching servers, each being capable of performing the matching operation,
wherein, prior to the performing the face authentication process, in response to at least one administrator entry operation on the terminal device, the server device stores information on the one or more matching groups, the information on the one or more matching groups identifying at least one matching group which is set for the each of the plurality of face authentication machines and identifying at least one of the one or more matching groups which is set for each of the plurality of face image matching servers, and
wherein, when the system performs the face authentication process, the each of the plurality of face authentication machines is configured to: acquire the information on the one or more matching groups from the server device to identify one or more of the plurality of face image matching servers for which each of the at least one of the one or more matching groups which is set for the each of the plurality of face authentication machines is similarly set, the identified one or more of the plurality of face image matching servers being configured to perform the matching operation for the each of the plurality of face authentication machines based on a similarly set matching group; and transmit a request for performing the matching operation to the identified one or more of the plurality of face image matching servers based on the similarly set matching group.
