Abstract :
Arnold transformation is applied widely in digital image scramble because of its periodicity. But we will waste lots of time when we used its periodicity to get the anti-Arnold transformation algorithm, especially when it used in the picture with big degree. So, in this paper, we use a new anti-Arnold transformation algorithm which got by solving equation groups. By this way, we needn´t to figure out the degree, which will save lots of time.
