Hugh Pickens DOT Com writes: When Edward Snowden first emailed Glenn Greenwald, he insisted on using email encryption software called PGP for all communications. Now Klint Finley reports that Snowden also used The Amnesic Incognito Live System (Tails) to keep his communications out of the NSA’s prying eyes. Tails is a kind of computer-in-a-box using a version of the Linux operating system optimized for anonymity that you install on a DVD or USB drive, boot your computer from and you’re pretty close to anonymous on the internet. "Snowden, Greenwald and their collaborator, documentary film maker Laura Poitras, used it because, by design, Tails doesn’t store any data locally," writes Finley. "This makes it virtually immune to malicious software, and prevents someone from performing effective forensics on the computer after the fact. That protects both the journalists, and often more importantly, their sources." The developers of Tails are, appropriately, anonymous. They’re protecting their identities, in part, to help protect the code from government interference. “The NSA has been pressuring free software projects and developers in various ways,” the group says. But since we don’t know who wrote Tails, how do we now it isn’t some government plot designed to snare activists or criminals? A couple of ways, actually. One of the Snowden leaks show the NSA complaining about Tails in a Power Point Slide; if it’s bad for the NSA, it’s safe to say it’s good for privacy. And all of the Tails code is open source, so it can be inspected by anyone worried about foul play. "With Tails", say the distro developers, "we provide a tongue and a pen protected by state-of-the-art cryptography to guarantee basic human rights and allow journalists worldwide to work and communicate freely and without fear of reprisal."
