Paper Abstract

A new image scrambling algorithm is proposed in this paper. The secret image is encrypted by both random scrambling based on blocks and grayscale transformation based on a pseudo-random sequence, using two keys respectively. The information embedding is implemented in the space domain through replacing the low four bits of the host image pixels with the high four bits of the secret image pixels. A simple system of image hiding and extraction using the proposed algorithm based on Matlab is realized, and its resistance to noising and cropping is analyzed Simulation results show that the proposed algorithm can extract the hided image without knowing the host image information, and has the advantages of simple implementation, large hiding capacity and good safety performance.
