Abstract
The client re quests authentication by transmitting the authentication information entered by the user, the MAC address of the network adapter, and the address change information as to whether or not the MAC address has been changed. When the authentication information and the MAC address are in agreement with the details of registration, and if a change in the MAC address is recognized from the address change information, the server regards the authentication as being a failure and issues an access refusal, thus completing the processing. If a change in the MAC address is recognized, the fact may be notified to the manager to issue an access permit or an access refusal in accordance with the manager'"'"'s instruction.
