PROBLEM TO BE SOLVED: To prevent spread of a leaked file by obscuring the files leaked to a pure P2P type file sharing network. SOLUTION: By continuously transmitting a large amount of file key information of a proxy file to the genuine information leak file on the pure P2P type file sharing network into the pure P2P type file sharing network, file key information of the genuine information leak file is obscured. Arbitrary random data are produced and transmitted to a reception request on the pure P2P type file sharing network based on the proxy file key information, and reception probability of the genuine information leak file is extremely reduced to prevent information leak spread.
