%X In the context of digital watermark technology, this paper introduced binary image based Arnold transform and periodicity, and discussed the calculation methods of image scrambling degree in detail so that it elaborated the best formula of image scrambling degree with the combination of pixel value variance as well as pixels and 4 differ of the gray-level. The results show that the calculating method of the best image scrambling degree can well reveal the consistency of binary image scrambling degree and subjective visual effects.
