PROBLEM TO BE SOLVED: To provide an information distribution system which can reuse data distributed once as an information distribution system which distributes data, including content data, provided by an information source provider, via a communication network. SOLUTION: To vary possible copy frequency information of data, which are saved on a PC as a receiving device and distributed from a distributing server, the PC sends a request for reuse processing to the distributing server. Then the PC receives a reuse information key from the distributing server and rewrites the possible copy frequency of the distributed data, according to the reuse information key.
