History of Computer Cryptography and Secrecy Systems History of Computer Cryptography and Secrecy Systems A secrecy technique where the existence of an actual message is hidden. The word is derived from the Greek words steganos (covered) and graphein (to write). Steganography is ancient technique that has been used for thousands of years as a primitive for secrecy systems and secret communications. In the first century, Pliny the Elder described how the milk from a thitymallus plant could be used as invisible ink. Another technique in ancient Greece and Persia involved shaving a messenger's head, writing a message on his scalp and waiting for the hair to grow back before sending the messenger to the destination. The technique primarily achieves security through obscurity and it's basic weakness is that if the message is discovered, the secret communication is revealed.
