In this paper, we investigated the problem of copyright infringement in the peer-to-peer (P2P) environment, and proposed a system for piracy tracking. Even though the BitTorrent P2P software is a very efficient way to transfer files, it has become the main tool used to pirate copyrighted materials. Thus, we studied the bit torrent packet itself in order to detect the destination and source of the piracy. The torrent meta-file which has hash values of the pieces of the shared content is also analyzed to identify copyrighted material. As a result, we proposed a tracking system for copyright protection against BitTorrent piracy. Our system consists of hash database, feature database, protocol analyzer, torrent meta-file crawler, and copyright identifier. In this tracking system, the content is identified by three ways. The first way is to use the info hash in the hash DB. The second way is to use the piece hash value in the hash DB. Last way is to use the feature of the content that is able to identify if the content is slightly changed from original. If the proposed system is installed on the ISP network, it is able to protect the content from BitTorrent distribution.
