Steganography actually the first form of cryptography discussed by David
Kahn in "The Codebreakers," albeit briefly. He uses it to describe such
ancient practices as tattoing a message on someone's shaved scalp and
allowing the hair to grow back.
It has become a popular topic in the past decade or so because of the
possibility of using digital images to hide messages.
