Steganography is excellent for bypassing surveillance precisely because you can share the image somewhere public. Sure in principle anyone looking at your images is communicating in a fashion, but throw in some "popular" types of images. Of course if someone knows you are using steganography it may break down, but if it were illegal to publicly encrypt stuff you really have little option. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
