"Have you ever felt that you are being watched in whatever you
do online? Websites seem to know who you are and can greet you with
your name when you visit them. Google always seems to know what you
are searching, even before you started the search. Getting scared?
Perhaps it's time to turn your privacy filter on.
"Tor is free software and an open network that helps you defend
against a form of network surveillance that threatens personal
freedom and privacy, confidential business activities and
relationships, and state security known as traffic analysis.
"What Tor does is to bounce your web communication around a
distributed network of relays so that no one will know where you
are from. By using Tor, it prevents anyone to learn what sites you
have visited, and also sites to find out where you are from."
