Interesting discussion going on over on the CISSP forum talking about a
paper on VoIP Steganography
http://arxiv.org/ftp/arxiv/papers/0805/0805.2938.pdf.


I don't have the brain cycles at the moment to really dig into this paper
and the math involved, but there seems to be two trains of thought to the
ensuing discussion.  One, that due to compression techniques used today, it
would be hard to inject extra bits into sound streams undetected or without
altering the actual signal.  The other thought, and the one the paper takes,
is that there are enough unused sections of the protocol (i.e. RTP) for
non-detectable messages.

Anyway, here's the paper itself.

enjoy.
