The Amnesic Incognito Live System or Tails is a Debian based Linux distribution aimed at preserving privacy and anonymity. Actually, it is the next iteration of development on the previous Gentoo based Incognito Linux distribution. All its outgoing connections are forced to go through Tor, and direct (non-anonymous) connections are blocked. The system is designed to be booted as a live CD or USB, and leaves no trace on the machine unless explicitly told to do so.
