The oldest documented case of steganography dates to 500 BC, in which Histiaeus, the ruler of Milteus, tattooed a message on the shaved head of one of his slaves and let the hair grow back. He then sent the slave to the Aristagoras, his son-in-law, who shaved the slave’s head again and revealed the message.
