A group of developers at the Digital Technology Group (DTG), formerly the Laboratory for Communication Engineering (LCE), at the University of Cambridge have released two Android applications that allow users to browse the web anonymously using The Onion Router. The Onion Router, commonly referred to as Tor, is free software designed to provide internet anonymity to users while browsing online. It does this by bouncing the communications around a distributed network of relays run by volunteers from all around the world, preventing visited sites from learning a users physical location.
