Digital image scrambling can make an image into a completely different meaningless image duringtransformation, and it is a preprocessing during hiding information of the digital image, which alsoknown as information disguise. Image scrambling technology depends on data hiding technologywhich provides non-password security algorithm for information hiding. Data hiding technology led toa revolution in the warfare of network information, because it brought a series of new combatalgorithms, and a lot of countries pay a lot of attentions on this area. Network information warfare is animportant part of information warfare, and its core idea is to use public network for confidential datatransmission. The image after scrambling encryption algorithms is chaotic, so attacker cannot decipherit.
