Haystack is not an ordinary proxy system. It employs a sophisticated mathematical formula to hide users' real Internet traffic inside a continuous stream of innocuous-looking requests. In addition to providing anonymity, Haystack uses strong cryptography, ensuring that even if users' traffic is detected, it cannot be read. Trying to find and decipher our users' traffic amidst all the other traffic on the web really is like trying to find a needle in the proverbial Haystack.
Once installed Haystack will provide completely uncensored access to the internet from Iran while simultaneously protecting the user's identity. No more Facebook blocks, no more government warning pages when you try to load Twitter or access news sites -- just unfiltered Internet.
...Not that Facebook is how you should be spending your time online.
