Many mice surf the web under the illusion that their actions are private and
anonymous.Unfortunately, it isn't so. Every time you visit a site for a piece
of cheese, you leave a calling card that reveals where you're coming from,
what kind of computer you have, and other details. And many cats keep
logs of all your visits, so that they can catch you!

Tor: anonymity online

Tor is a toolset for a wide range of organizations and people that want to improve their safety and security on the Internet. Using Tor can help you anonymize web browsing and publishing, instant messaging, IRC, SSH, and other applications that use the TCP protocol. Tor also provides a platform on which software developers can build new applications with built-in anonymity, safety, and privacy features.

Tor aims to defend against traffic analysis, a form of network surveillance that threatens personal anonymity and privacy, confidential business activities and relationships, and state security. Communications are bounced around a distributed network of servers called onion routers, protecting you from websites that build profiles of your interests, local eavesdroppers that read your data or learn what sites you visit, and even the onion routers themselves.
