A study on countermeasure technologies against information leakage through information networks

为解决P2P文件共享系统中的信息泄露问题，提出了一些基本技术。首先，我们针对一个典型的P2P系统BitTorrent，提出了(1)一种有效的数据分发技术来控制泄漏信息(如虚拟数据分发)和(2)一种控制泄漏信息扩散的技术。接下来，我们使用网络模拟器对这些技术进行评估。结果发现，我们的方法可以比以前的方法更有效地控制数据扩散。

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.
