Everyone who surfs the Net is eminently trackable. Internet data packets include not only the actual data being sent, but also headers with routing information that is used to guide the packages to their destinations. Even if you use encryption for extra safety, the routing information -- which cannot be encrypted -- can reveal details about what you're doing, who you're talking to, what services you're connecting to, and what data you're accessing. Intermediaries (authorized or not) can also see that data and learn about you. If you want a higher level of anonymity, TorK can do the job. It uses The Onion Router (Tor) network to provide you with a safer way of browsing.
Tor sends your network packets through a network of encrypted virtual tunnels, creating a practically untraceable path back to you. When you want to connect to a specific URL, you first connect to a Tor server, which in turn sends the packets to another Tor machine, and so on, until your traffic eventually reaches its destination by means of a complicated, untrackable route. If you make another connection, you get a new route. Anybody who wanted to trace the packets back to you would have to go through several steps, and without any logging to reveal where your traffic came from, the trail would quickly become impossible to follow.
