The puzzles esteganografia are presented by Cicada incorporate steganography with cryptography and other solving techniques since The noise provides enough variation in the captured digital information that it can be exploited as a noise cover for hidden data. Some implementations of steganography that lack a shared secret are forms of security through obscurityand key-dependent steganographic schemes adhere to Kerckhoffs’s principle.

Others, however, esteganografia resistant to detection – or rather esteganografia is not possible to reliably distinguish data containing a hidden message from data containing just noise – even when the most sophisticated analysis esteganografia performed.
