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.
Steganalysis tools by Niels Provos, doctoral candidate at the University of Michigan at Ann Arbor, include the following:
- Stegdetect identifies possible steganographic images based on value distributions
- Stegbreak, which uses dictionary guessing to break the encoding password
- In development: self-teaching tools that will understand the common values in image and sound files
