ScienceLives interview with Roger Dingledine
Computer scientist and Internet rights advocate Roger Dingledine has spent his own career trying to change that. As a grad student at MIT, he and his coworkers developed an early anonymity system for Internet communications, which became the forerunner of what he now calls "Tor," or, The Onion Router. Onion is a metaphor for the system's many encryption layers that protect a user's identity. Tor directs Internet traffic through a free, worldwide, network consisting of more than 5,000 volunteer relays to conceal a user's location or usage from network surveillance or traffic analysis.
