Abstract
An authentication server, on receipt of a request to delete a user account, determines whether the account exists in a user authentication table. If the account exists, the authentication server deletes the account, and retrieves, from a requesters list in which information of devices from which users have to date requested user authentication is saved, an address of a device from which the user targeted for deletion has previously issued an authentication request, and issues a deletion request to that device together with account information. Similar processing to change a user account is performed in response to a change request.
