Use in the file sharing networks
This software can be easily used for anonymous file sharing. An uploader downloads legal images from the public photo hosting, after that embeds in them censored file, then uploads pictures to the public photo torrent tracker and the link referencing stego pictures with censored file's description puts on forum or blog. Downloaders and seeders, as also public photo trackers, if caught distributing illegal files, are protected from legal prosecution, because they can always use plausible deniability that they did not knew about illicit file in the images (it is impossible to prove the opposite, human eye cannot see the difference between ordinary image and picture with embedded hidden file). It is absurd to start litigation against seeder of the stego images.
