4. The network service system using a temporary user identifier according to claim 3, wherein

said temporary user identifier update request transmitting side device or said temporary user identifier update request receiving side device which transmits the association deletion reply message retrieves notice information to the user and transmits an association deletion notice message to said user proxy device using the retrieval results.

5. A network service system using a temporary user identifier, where information of a user using a plurality of services is shared by the plurality of services, comprising:

a temporary user identifier update request transmitting side device which provides a first service to a user and can transmit an update request of a temporary user identifier shared within the network service system as information of the user;

a temporary user identifier update request receiving side device which is connected to said temporary user identifier update request transmitting side device by a network and can receive the update request of a temporary user identifier that is transmitted from said temporary user identifier update request transmitting side device, for providing a second service cooperating with the first service to the user using an updated temporary user identifier corresponding to the update request; and

a user proxy device which is connected to said temporary user identifier update request transmitting side device and said temporary user identifier update request receiving side device by the network, and with which the user receives the first and the second services, wherein;

said user proxy device generates a temporary user identifier using an irreversible operation corresponding to a user identifier of the user for a service provided in each of said temporary user identifier update request transmitting side device and said temporary user identifier update request receiving side device, and it transmits to said temporary user identifier update request transmitting side device and said temporary user identifier update request receiving side device an association registration request message including the generated temporary user identifier and notice information to the user, which is used when an association is deleted before a valid time period of the generated temporary user identifier expires; and

each of said temporary user identifier update request transmitting side device and said temporary user identifier update request receiving side device transmits an association reply message to a side of the user proxy device after setting the temporary user identifier, a valid time period of the temporary user identifier and notice information to the user.

6. A network service system using a temporary user identifier, where information of a user using a plurality of services is shared by the plurality of services, comprising:
