Steganography is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography takes cryptography a step farther by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning your data will fail to know it contains encrypted data. This is different from cryptography, which hides the meaning of a message but does not hide the message itself. An example of a steganographic method is "invisible" ink.
