| Abstract: | With the research background of image information security, the periodicity of Arnold contrary transformation of three dimensions and n dimensions is discussed in the article.A theorem is given to estimate the upper bound of the periods. The function of the three dimensions Arnold contrary transformation in digital image scram bling is proved by experiment. |
