If you e-mail your friend directly, the Guard’s network could easily see your computer’s IP address, and discover your name and personal information. But if you’ve installed Tor, your e-mail gets routed to one of 2,000 relays — computers running Tor — scattered across the world. So your message bounces to a relay in Paris, which forwards it to a second relay in Tokyo, which sends it on to a third relay in Amsterdam, where it is finally transmitted to your friend in Tehran. The Iranian Guard can only see that an e-mail has been sent from Amsterdam. Anyone spying on your computer would only see that you sent an e-mail to someone in Paris. There is no direct connection between San Francisco and Tehran. The content of your e-mail is not hidden — for that, you need encryption technology — but your location is secure.
