More on steganography

Computerworld - Online Resources
There are about a dozen freeware sites on steganography. But data-hiding instructors at New Technologies Inc. in Gresham, Ore., recommend the Web site of Neil Johnson, IT consultant and associate director at the Center for Secure Information Systems at George Mason University in Fairfax, Va.
Favorite tool: F5 steganography with robust encryption.
