Tails

The Amnesiatic Incognito Live System! Used successfully by Snowden to break news to the Guardian about NSA Prism Program. "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.

It is a complete operating system designed to be used from a DVD, USB stick, or SD card independently of the computer's original operating system. It is Free Software and based on Debian GNU/Linux.

Tails comes with several built-in applications pre-configured with security in mind: web browser, instant messaging client, email client, office suite, image and sound editor, etc.

It aims at preserving your privacy and anonymity, and helps you to:

  • use the Internet anonymously and circumvent censorship;
    all connections to the Internet are forced to go through the Tor network;

  • leave no trace on the computer you are using unless you ask it explicitly;

  • use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging."


Ubuntu

Ubuntu is a free and open sourceed Debian-based Linux operating system, with Unity as its default desktop environment. It is named after the Southern African philosophy of ubuntu (literally, "human-ness"), or "the belief in a universal bond of sharing that connects all humanity". This operating system works very similar to mac or windows but without the privacy compromises and allowing users to encrypt the home and private directories.
