On the subject of stego, this showed up earlier this week:
To: cypherpunks@lne.com
Subject: P2P Stego Treasure Hunt
We've put into Morpheus a song,
"Grayson_Shoot_The_Piano_Player.mp3"
which has a stego'd message in it.
The tool is mp3stego v 1.1.15
(source available; see
<http://www.cl.cam.ac.uk/~fapp2/steganography/mp3stego/>
) and the (3DES) passphrase is "writecode"
Another file "DrDidg_RaveOn.mp3" has
another message under the same passphrase.
We are curious how readily the Morpheus search
engine can be used for transport purposes. In
this instance we give unique names to files not
otherwise found in the system. Another experiment
in P2P percolation would be to add similar
'watermarks' (microdots) to files which are
abundantly replicated.
