Tails

Tails stands for The Amnesic Incognito Live System, which is designed for preserving privacy and anonymity. It allows the users to use the internet anonymously and also circumvent censorship via tor network.  The tails leave no trace and enable the users to use the state of the art cryptographic tools for encrypting files, emails and other specific messages. It can be run from a bootable DVD, USB flash drive or flash memory card.
