The following pages use steganography techniques to hide secret information invisibly in an image or audio file. They modify the least-significant bits of the pixels in an image, or add "noise" to audio samples to hide information.
The best way to protect the privacy of your private communications is to make it hard to determine that any private communications are taking place! After all, you're just mailing pictures of funny kittehs!!!1
These pages use the steghide program to perform steganography, and the files generated are fully compatible with steghide. If you really want to be secure, or do brute-force attacks, you'll want to use these programs on your own system.
