Chaotic iterations versus Spread-spectrum: chaos and stego security [PDF]
, 2010 A new framework for information hiding security, called chaos-security, has been proposed in a previous study. It is based on the evaluation of unpredictability of the scheme, whereas existing notions of security, as stego-security, are more linked to ...
