A fingerprint authentication server device is disclosed. The fingerprint authentication server device includes a database in which user IDs and the registered fingerprint data of plural users are stored; and a hash value table including user hash values of the user IDs and the registered fingerprint data of the users. 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 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.
