Steganography
Is the art and science of writing hidden messages in such a way that no
one apart from the intended recipient knows of the existence of the message;
this is in contrast to cryptography, where the existence of the message itself
is not disguised, but the content is obscured. The word "Steganography" is of
Greek origin and means "covered, or hidden writing".
Its ancient origins can be traced back to 440 BC.
