Peer-to-peer (P2P) systems are popularly used as “file swapping” networks to support distributed content sharing. A number of P2P networks for file sharing have been developed and deployed. Napster, Gnutella, and Fasttrack are three popular P2P systems. This chapter presents a broad overview of P2P computing and focuses on content sharing networks and technologies. It also emphasizes on the analysis of network topologies used in popular P2P systems. In addition, this chapter also identifies and describes architecture models and compares various characteristics of four P2P systems—Napster, Gnutella, Fasttrack, and OpenFT.

File sharing is one of the most popular applications in peer-to-peer networks where there is no control over what the peer can download or upload. This explains why file sharing got a high percentage of the overall internet traffic. Although file sharing is a legal technology, many users use it to share copyrighted materials and that's why many applications have been sued and shut down. In this thesis we will build a secure and legal file sharing system using Java bindings of JXTA protocols. The application security is derived from using digital certificates signed by a server peer who acts like a certificate authority (CA), all communications are encrypted using these digital certificates. The legal side is derived from the fact that each peer has a tokens account that will be updated and signed by the server peer only. The downloading peer has to pay some tokens for downloading a file to the uploading peer who then contacts the server peer to credit its commission from that payment. The server peer is the only one who can cash those payments to make the system forgery protected. The interaction between peers and the server peer could be on monthly basis so peers can download and upload files easliy and without the presence of the server. At the end we analyzed the security aspects and show how the implementation deals with most known peer-to-peer threats.

Canada is in the midst of a contentious copyright reform with advocates for stronger copyright protection maintaining that the Internet has led to widespread infringement that has harmed the economic interests of Canadian artists. The Canadian Recording Industry Association (CRIA) has emerged as the leading proponent of copyright reform, claiming that peer–to–peer file sharing has led to billions in lost sales in Canada. This article examines CRIA’s claims by conducting an analysis of industry figures. It concludes that loss claims have been greatly exaggerated and challenges the contention that recent sales declines are primarily attributable to file–sharing activities. Moreover, the article assesses the financial impact of declining sales on Canadian artists, concluding that revenue collected through a private copying levy system already adequately compensates Canadian artists for the private copying that occurs on peer–to–peer networks.
