The Haystack application aims to use steganography to hide samizdat-type data within a larger stream of innocuous network traffic. Thus, civilians in Iran, for example, could more easily evade Iranian censors and provide the world with an unfiltered report on events within the country. Haystack earned its creator Austin Heap a great deal of positive coverage from the media during the 2009 Iranian election protests. The BBC described Heap as "on the front lines" of the protesters' "Twitter revolution", while The Guardian called him an Innovator of the Year. Despite the laudatory coverage, however, the media were never given a copy of the software to examine. Indeed, not much is known about the software or its inner workings. Specialists in network encryption security were not allowed to perform an independent evaluation of Haystack, despite its distribution to and use by a small number of Iranians, possibly at some risk. As interest in the project widens and criticisms of the media coverage and software continue to mount, Heap has currently asked users to cease using Haystack until a security review can be performed.
