Introduction to Steganography

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography is of Greek origin and means "concealed writing" from the Greek words steganos(στεγανός) meaning "covered or protected", and graphei(γραφή) meaning "writing".
