Steganography: A Brief History
Steganography, from the Greek words steganos (covered) and graphein (to write), is the practice of concealing messages within other non-secret data.
Ancient Origins
The earliest recorded use of steganography dates back to 440 BC, when Histiaeus shaved a slave's head, tattooed a message on his scalp, and waited for the hair to regrow before sending him as a messenger.
Digital Era
Modern digital steganography encompasses a wide range of techniques:
