Stego for Video ?

[Matthew Bernardini <matthew@gandalf.rutgers.edu>]

Have any programs been written that would allow for three dimensional stego
in moving pictures ?  I think this would make it a little more difficult to
detect.

How about more advanced graphical techniques like using a stego file as a map
in a renderer ?  The person who received the picture would know for instance
that all the vertical walls, or all the brick surfaces, etc were stego
encrypted messages.  It would take some sophistication to reverse engineer
the rendered picture, but necessity is the mother of invention.  The actual
image would not contain any specific information, but would be a disguised
"envelope" for other pictures within the picture.
