Abstract :
An image scrambling algorithm based chaos and wavelet transform is proposed in this paper. Scrambling is performed in wavelet domain in order to resist statistical analysis attack. Due to the advantages of the confusion and diffusion characteristics of the two-dimensional chaotic sequences, the algorithm obtains good scrambling effect and security. Experiments show that the algorithm can endure commonly image attacks
