Tor: An anonymous Internet communication system: Tor is an anonymizer on steroids. It was built by the U.S. Navy, of all groups, and is currently maintained by the EFF.

Your traffic is safer when you use Tor, because communications are bounced around a distributed network of servers, called onion routers. Instead of taking a direct route from source to destination, data packets on the Tor network take a random pathway through several servers that cover your tracks so no observer at any single point can tell where the data came from or where it’s going.
