An Image-Based Information Hiding Approach with Chaotic Systems and Optimized Security



Recently, information hiding has become an important approach to the secure storage and transmission of important information in digital media.



This paper proposes a new approach that can hide information in a color image with optimized security.



The approach performs the hiding in two phases. Firstly, the information that needs to be hidden in an image is represented by a sequence of binary bits, and the sequence is shuffled and encrypted with a set of three-dimensional chaotic systems. Secondly, the binary bits in the shuffled and encrypted sequence are hidden into the R, G, and B components of the pixels in the given color image with a dynamic programming approach.



Experimental results show that the proposed approach is able to securely hide information in a color image without generating significant changes in the visual contents of a color image. Analysis also shows that the proposed approach is robust against potential attacks.



The proposed approach is thus practically useful for applications aimed at image-based information hiding.
