<p>An agent system distributes a program. A server (10) transmits a service ID specified uniquely within a distribution system, and transmits a program with the service ID to a client terminal that requests the program with the transmitted service ID. A client terminal (20) requests the issue of a service ID prior to a request of a required program (3), receives the service ID from the server, and sends a request for a program, together with the service ID. Only if the received program is in agreement with the attached service ID, the client terminal permits the execution of the program.</p> |
