SYSTEM, SERVER APPARATUS, AUTHENTICATION METHOD, AND STORAGE MEDIUM

A system includes a server apparatus and at least one or more authentication terminals. The server apparatus stores an ID of each of a plurality of users and biometric information in association with each other. The at least one or more authentication terminals maintain an ID list that stores IDs of at least one or more persons staying in a predetermined area. The at least one or more authentication terminals transmit an authentication request, the authentication request including biometric information of a person to be authenticated and the ID list, to the server apparatus when an authentication of the person to be authenticated is required. The server apparatus extracts IDs included in the ID list from the ID of each of the plurality of users and performs biometric authentication using biometric information corresponding to the extracted IDs and the biometric information included in the authentication request.
