Yesterday I asked about Haystack, an anti-censorship system that appears to exist mainly as newspaper articles. So today I ran across another system, which appears to be real: Collage (http://gigaom.com/2010/07/12/software-uses-twitter-flickr-to-let-dissidents-...), developed by a group at Georgia Tech and to be presented at Usenix. On a crypto level, unlike Haystack, Collage is nothing new: It uses steganographic techniques to hide text in photos. What it contributes is easy to use software for both embedding and extracting the data, integrated with Flickr.

Unlike haystack - this software appears to be real and to have contributed something useful to the field of anti-censorship. Impressive research!
