Steganography is the practice of hiding information within another message or physical object so that it's not obvious to human inspection. The word comes from the Greek words steganos, which means "covered" or "hidden," and graph, which means "to write". Steganography can be used to hide any type of digital content, including text, image, video, or audio content. The hidden data is then extracted at its destination.
