There has emerged a set of new technologies that provides protection with or without data encryption technology such as data hiding. The word steganography (from Greek steganos, or \"Covered,\" and graphie, or \"Writing\") is the hiding of undisclosed message (such as text) within an ordinary message (such as image).
