Steganography

The word steganography consists of two parts: ‘stegano’ and ‘graphy’, both of which are of Greek origin. Stegano means “covered” and graphein means “to write”. Therefore, steganography represents the art of covered or concealed writing. In simple terms, steganography is the art of hiding text and images such that only the sender and the intended receiver can read the message. For others, the message looks like an innocent message.
