摘要

PROBLEM TO BE SOLVED: To provide a system securing high operation reliability using respective functional objects cooperatively by giving authorization to the respective functional objects for preventing unauthorized utilization or modification of them and surely grasping whether the functional objects are formally authorized or not as a system representing a plurality of functional resources, which have operation effects fluctuating variously according to combination between them, as the functional objects in a virtual space.;SOLUTION: It is compared and determined whether a name identifier included in the functional object data transmitted from a functional object data supplying device has a predetermined relationship with a previously decided reference name identifier or not. If it has the predetermined relationship, authorization of the functional object data is finished, and these functional object data are distributed to a functional object data distribution device and a functional object representation device via a communication network.;COPYRIGHT: (C)2004,JPO
