A scheme of triangular-hiding based on two-dimensional chaotic maps
Hongmei Wang, Limin Qu · 2013
In this paper, we propose a scheme of triangular-hiding based on two-dimensional chaotic maps. The pixel positions of the image are scrambled by Baker map, and then the scrambled image is hidden by triangular algorithm. The experimental results show that, this scheme realizes double encryption, and it increases the difficulty of decipher, the key space is larger, the stego-image's fidelity is high, we can encipher images of any size, it can be realized quickly.
