Security Protected

Content security and copyright protection have brought a constant battle between the content industry and P2P content-sharing companies and users in the last several years. On one hand, many users are enjoying free content distributed via P2P file-sharing and streaming applications. On the other hand, content creators and their representatives are trying to stop unauthorized sharing. While taking file-sharing companies and individuals to court, the content industry also learned to take advantage of the distributed resources and other characteristics of P2P networks to sabotage P2P file-sharing systems themselves.

One of the techniques they used is called pollution. The goal is to stop P2P file sharing by causing user frustration. The basic idea is to create bogus content, especially popular content, and store it in a P2P file-sharing system. When peers search for files on these systems, they could be directed to the bogus ones. The chaining effect of such sharing will result in a large number of peers getting constant bogus content so that they become frustrated with the system and thus abandon it voluntarily.
