Pl-to-PI: A solution towards secure peer to peer communication network

File sharing is a corner stone application of network computing. The most popular way to achieve an efficient file sharing through the Internet is to use Peer-to-Peer (P2P) protocols via applications such as BitTorrent. However, BitTorrent is an open file sharing service that allows files to be shared widely without the consent, or control, of the original publisher of the work. Such a fact is undesirable for a lot of organizations and institutions since it raises copyright and content ownership issues. In this paper we propose an efficient BitTorrent-like protocol that aims at privatizing the P2P network such that control over the distribution of copyrighted material can be achieved. This is done by limiting the user set to those authorized based on their machines MAC addresses and by using dedicated equipment, i.e. the Raspberry PI board.
