![]() ![]() cours judged that P2P website operators can be held legally responsible for data their users share. In case of copyrighted material sharing using conventional P2P networks, U.S. Further, a client can download data from any peer that has the requested piece, even if that peer has not received the entire file. The use of multiple peers allows the data to potentially be downloaded faster than if connected to just a single peer. A client on a BitTorrent network can connect to multiple peers without a central server, and download small pieces of a file from multiple peers at the same time. BitTorrent links each client without a central server, and shares fixed size data pieces of a shared file to make sharing fast and fault tolerant. ![]() BitTorrent, however, is different from conventional P2P networks. This mechanism allowed communication and sharing of files between clients through the server. Where a central server manages and links each client by indexing all of the current users and searching their computers for shared data. Ĭonventional P2P software consists of a central server-based model. However, currently BitTorrent is the most widely used peer-to-peer file sharing protocol. Kim suggested a methodology to enable a fault-tolerant scheme for stable streaming services over P2P networks. There are many attempts to make the data sharing process more efficient. Although P2P is a useful technology that makes data transmission fast and reliable, it has also been abused for copyrighted file sharing purposes. There are many kinds of P2P network protocols, such as Opennap, Gnutella, Grokster, Freenet, eDonkey2000, and BitTorrent. P2P allows users to download media files such as music, movies, and games using a P2P software client that searches for other computers connected to the same logical network. P2P is one of technology for efficient data sharing. And, Kun suggested a method for designing a secure and efficient mix network. Liu suggested a method for adjusting traffic in Wireless Mesh Networks. There are lots of technologies that enabling efficient data sharing in different environment. However, despite implemented law, illegal file sharing through P2P networks persists. There are various laws that have been imposed to punish illegal file sharers in many countries. The act of downloading copyrighted work without copyright holder’s permission infringes on their right to reproduction. The act of uploading copyrighted work without a copyright holder’s permission infringes the right of reproduction and transmission of the copyright holder. Therefore, sharing copyrighted material without a copyright holder’s permission is considered illegal in many jurisdictions. Intellectual Property (IP) is a legal concept that refers to creations of the mind for which exclusive rights are recognized. This paper proposes a methodology for the investigation of illegal file sharers using BitTorrent networks through the use of a P2P digital investigation process. As a result, it is difficult to apply previous investigation processes for investigation of conventional P2P networks to the investigation of suspected illegal file sharing using BitTorrent. ![]() ![]() This is because the role of the server in BitTorrent networks has been changed compared to servers in conventional P2P networks. Further, there is a lack of research on investigation techniques to reveal illegal BitTorrent sharers. However, it is difficult to gather enough probative evidence to prosecute illegal file sharers in criminal court and/or sued for damages in civil court. Regardless, the number of illegal file sharing using BitTorrent continues to grow and most of file sharers and downloader are unconcerned legal action to transfer copywrite-protected files. Sharing copyright protected content without the copyright holder’s permission is illegal in many countries. ![]()
