Steganography 101 using Java

Steganography 101 using Java: "As mentioned above, cryptography is often used in situations where the existence of the message is clear, but the meaning of the message is obscured. In particular, the sender transforms the message into a form that (hopefully) only the intended recipient of the message can decrypt and read. Steganography is often used in situations where the actual existence of the message needs to be obscured." Un'introduzione alla steganografia piuttosto interessante e corredata da esempi di codice e di immagini steganografate.
