A 4D Symmetric Chaotic System and Its Application on Image Hiding
WU Song-xian · Computer Technology and Development · 2010
Chaotic dynamical systems play an important role in information security thanks to their good properties such as the sensitive dependence on initial conditions and system parameters,topological transitivity,pseudo-random property,etc.In particular,high dimensional chaotic dynamical systems have attracted more attentions in recent years thanks to their higher security.One four-dimensional symmetric chaotic system is constructed in this paper;an image hiding scheme is proposed,in which the technologies of image scrambling,encryption,sharing and hiding are applied together.The presented scheme is simple to manipulate and has high security.It is robust against some kinds of attacks and it can reconstruct the secret images and cover images in a lossless manner as well.
