| Abstract: | As the rescarch background of image imformation securing,and starting from Arnold transformation,two dimensions Arnold transformation are firstly discussed.Secondly three dimensions Arnold transformation are discussed and its popularization in n dimensions.At last,put forward a digital image scrambling improved algorithm based on RGB colour space.Experimental results demonstrate that the proposed algorithm has very obvious encrypted effect,can increase robustness of digital watermarking. |
