About 2 years ago I have implemented the Steganalysis method based on paper "Steganalysis by Subtractive Pixel Adjacency Matrix" http://www.ws.binghamton.edu/fridrich/Research/paper_6_dc.pdf http://www.ws.binghamton.edu/fridrich/Research/paper_6_dc.pd.... The whole evaluation was done by embedding random messages and the method worked well so I guess encryption of the datastream won't help much.
