The anti-internet filtering software, Haystack, received the necessary export license from the US government last week to sell their product to Iran in an effort to help Iranian citizens gain free speech. Inspired by the internet restrictions during the June 2009 elections, the software uses mathematical formulas to mask users’ identities and to allow them to access and post items on government blocked websites such as Facebook, Twitter, Gmail and YouTube. Haystack was created by the non-profit Censorship Research Center in San Francisco, and according to the company’s executive director, Austin Heap, the only way to disable the software is by disabling the entire internet.
