In order to improve performance of image scrambling, applied chaos system to image scrambling,which was extremely sensitive for initial value, aperiodic, ergodic and pseudo-random. Then proposed a new digital image scrambling algorithm based on chaos. In order to get the best scrambling effect, used shuffled frog leaping algorithm to optimize parameters of the proposed algorithm. The emulation experiments show that the proposed algorithm has good scrambling effect and strong ability in resisting shear attacks and noise attacks.
