Tails - Live operating system which preserves privacy and anonymity

Tails is a live system that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly. Tails relies on the Tor anonymity network to protect your privacy online. It encrypt and sign your emails and documents using the de facto standard OpenPGP either from Tails email client, text editor or file browser.
