Steganography is the art and science of writing hidden messages in such a way

that no one, apart from the sender and intended recipient, suspects the existence

of the message, a form of security through obscurity. The word steganography is

open source programs for Linux that you can use to play with this concept:

Steghide and Outguess and one closed source Steg

From the Steghide -- Download  PAGE:
