Find out more about steganography

• What is steganography?
• check out historical and commercial uses of steganographic technology;
• for hiding small messages such author identity or passwords within text, try my poetry heuristics for natural-language steganography (source code for Unix), which uses a very simple form of chaffing and winnowing;
• for larger data sets there is Derek Upham's JSTEG image coder;
• For inexpensive data hiding, try stego source code from fourmilab.ch.

Wanted: sophisticated steganographs
