Abstract:
1. A fingerprint authentication server device comprising: a database in which user IDs and registered fingerprint data of plural users are stored; and a storage in which a hash value table is stored, the hash value table including user hash values of the user IDs and the registered fingerprint data of the users, wherein the fingerprint authentication server device is configured to receive a hash value of a user ID of a user to be authenticated and a hash value of the registered fingerprint data associated with the user ID from a client computer; perform a search in the hash value table to determine whether there are hash values corresponding to the received hash values in the hash value table; and transmit a determination result to the client computer, thereby to cause the client computer to perform a fingerprint authentication process for a user for which correspondence of the hash values has been confirmed.
