Software developers are designing some new file sharing networks that will make it harder for the music and file industry to prove cases of piracy. According to Reuters, three file sharing networks are being planned which its users think will make it a lot harder for music industry to track and charge people on their networks. Techniques being used are: a) multiple Internet protocol (IP) addresses, b) files in the network are disguised to look entirely generic, c) multiple IP addresses are taken from other users on the network to camouflage individual activities, d) use of third-party proxies' computers to disguise trails of sharers, e) encryption to protect identity of users.
