This study proposes some basic technologies for solving information leakage problems in P2P file sharing systems. To begin with, we focus on a typical P2P system, BitTorrent, and propose both (1) an efficient data distribution technology for controlling leaked information (e.g.dummy data distribution) and (2) a control technology on diffusion of leaked information. Next, we evaluate these technologies by using network simulator. As a result, it is found that our proposals can control data diffusion more effectively than the previous methods.
