Image scrambling algorithm based on bit-plane and Gray code
Miao Ma · Computer Engineering and Applications Journal · 2010
Aiming at the safe problem of image transmission,this paper presents an image scrambling algorithm based on bitplane decomposition and Gray code.Firstly,the original image is decomposed into eight bitplanes,and then its four bitplanes possessing more useful information are changed via a bitwise exclusive or operator.Finally,Gray code transformation is employed to improve the scrambled effect.The experimental results show that the algorithm not only is superior to several existing methods,such as Arnold,Hilbert,MSB or chaos scheme,but also can be easily implemented.
