Computer Vision: Steganography, The Ancient art of Concealing Messages #datascience

Steganography is a cryptographic technique that involves hiding messages in digital files. It is the practice of hiding a file, message, image, or video within another file, message, image, or video. The word steganography is derived from the Greek words "steganos" (meaning hidden or covered) and "graphe" (meaning writing). Steganography is the use of various methods to hide information from unwanted eyes. In ancient times, steganography was mostly performed physically. The earliest documented case of steganography dates back to 500 BC, when Histiaeus, ruler of Miltaeus, tattooed a message on the shaved head of one of his slaves and let his hair grow back. He then sent the slave to Aristagoras, his son-in-law, who shaved his head again and revealed the message to him.
