In this article, the author discusses a computer program called Psiphon which bypasses government filters undetected. The University of Toronto's Citizen Lab, a research center for digital media and politics, designed Psiphon for technology-savvy activists. Some technology-savvy activists use other open-source software, like Tor (which relies on servers at Harvard University and the Massachusetts Institute of Technology), to circumvent what they call "silly" government restrictions. But people must download files to run those programs--a risk in Iran, where having such files on your computer can lead to jail. Psiphon, is Web-based: Users download nothing, leaving no clues for snoops. It could open the Internet to thousands of students who use public terminals. To use Psiphon, people in censored countries need social connections to people in uncensored countries, and Western universities house huge populations of technology-savvy and politically fired-up foreigners. Psiphon's reliance on social networks means censored users will find circumvention easier than ever.
