An anonymous P2P communication system is a peer-to-peer distributed application in which the nodes or participants are anonymous or pseudonymous. Anonymity of participants is usually achieved by special routing overlay networks that hide the physical location of each node from other participants. Interest in anonymous P2P systems has increased in recent years for many reasons, ranging from the desire to share files without revealing one's network identity and risking litigation〔Electronic Frontier Foundation (2005). (RIAA v. The People: Five Years Later ). Retrieved March 5, 2008.〕 to distrust in governments, concerns over mass surveillance and data retention, and lawsuits against bloggers.〔Julien Pain, editor (2005). (Reporters Without Borders handbook for bloggers and cyber-dissidents ). Retrieved January 23, 2008.〕 ==Motivation for anonymity== There are many reasons to use anonymous P2P technology; most of them are generic to all forms of online anonymity. P2P users who desire anonymity usually do so as they do not wish to be identified as a publisher (sender), or reader (receiver), of information. Common reasons include: * Censorship at the local, organizational, or national level * Personal privacy preferences such as preventing tracking or data mining activities * The material or its distribution is considered illegal or incriminating by possible eavesdroppers * Material is legal but socially deplored, embarrassing or problematic in the individual's social world * Fear of retribution (against whistleblowers, unofficial leaks, and activists who do not believe in restrictions on information nor knowledge) A particularly open view on legal and illegal content is given in (The Philosophy Behind Freenet ). Governments are also interested in anonymous P2P technology. The United States Navy funded the original onion routing research that led to the development of the Tor network, which was later funded by the Electronic Frontier Foundation and is now developed by the non-profit organization The Tor Project, Inc. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「anonymous p2p」の詳細全文を読む スポンサード リンク
