the problem with many current stego programs (jsteg/stools) is that given a data stream, they will tell you if there is data steg'ed (by the same program, of course) it in. jsteg goes out of it's way to hide it's content-length header, but jsteg can still detect jsteg headers...
Just a stab, but maybe this might work: Get two picures of with both at minimum sufficient size to carry the message. Use the lsb's (or any bit for that matter) of the second image to XOR with the message before stego'ing (L'eggo my S'tego :) into the first. Of course you'ld have to arrange which bit in the pad image will be used, how to associate the images, etc. before hand. --- Fletch __`'/| fletch@ain.bls.com "Lisa, in this house we obey the \ o.O' ______ 404 713-0414(w) Laws of Thermodynamics!"
