Beat censorship by hiding secret messages in Flickr photos

Beat censorship by hiding secret messages in Flickr photos
Georgia Tech researchers have developed a tool called Collage that will allow Internet dissidents to insert hidden messages into Twitter posts and Flickr images in order to circumvent the censorship measures imposed by oppressive governments.
The tool, which is implemented in Python and uses the OutGuess framework, relies on a technique known as steganography to weave hidden messages into an image file. It uses an automated testing tool called Selenium to facilitate the deployment of the messages. The researchers believe that hiding subversive messages inside content that is indistinguishable from legitimate social network activity will reduce the chances of detection.
