Detection of the Music or Video Files in BitTorrent

Nowadays the Internet has been spreading widely all over the world and the network traffic has been increasing rapidly in the Internet. Peer-To-Peer (P2P) networks have been used widely in order to deliver operating system DVD image or several packages of commercial software, but everyone does not always use P2P networks rightly or legally. One of the examples of illegal usage of P2P networks is to exchange the audio or video files which violate copyrights. BitTorrent is one of the P2P networks that are used relatively rightly. This paper proposes the method which detects illegal file exchange of BitTorrent. This paper regards video or music files exchanged by BitTorrent as illegal files and proposes the method which detects the video or music files exchanged by BitTorrent. This paper also implements this method in BitTorrent software and evaluates this method.
