摘要： PROBLEM TO BE SOLVED: To prevent a program downloaded in a client terminal by way of a network from performing an unlawful processing that a user does not intend. SOLUTION: A client terminal 400 transmits a service requests including an object identifier of a client object program, its programmer signature and position information on the client terminal 400 to an execution server 401. Only when it verifies the programmer signature and confirms its completeness, the execution server 401 retrieves the object identifier and its programmer name from a client object management file 1625. Only when they are retrieved, service use authority of a user is confirmed by referring to an access management file 1624. Then, only when there is the use authority, a server object program is executed and services are provided.
