When the Tor Project was announced a decade ago, Google was still largely seen as fulfilling its corporate motto, “Don’t be evil,” and Twitter didn’t even exist. But researchers Roger Dingledine, Nick Mathewson, and Paul Syverson could already see trouble on the horizon. Created in a U.S. naval lab to safeguard government communications, their brainchild the Tor Project is designed to protect anyone and everyone from the dangers of Big Brother. The free software, now relied on by hundreds of thousands of users daily, bounces information through the computers of 3,000 volunteers around the world, hiding the identity of the original user.
