Abstract
A high capacity lossless information hiding algorithm that based on histogram shift of prediction residual image is proposed in this paper. Prediction residual image is established by calculating the difference between each pixel and the reference pixel according to the proposed scan orders. Then secret information is embedded by using the method of histogram to shift multiple histogram peaks of prediction residual image, when information hiding is proceed for multiple times, the problem that embedding capability will decrease along with the increase of the embedding levels is improved by alternately changing the scan orders. Experiment results are provided to demonstrate that the proposed algorithm is superior to the other state of art schemes in the terms of embedding capability versus PSNR while image distortion can be still acceptable when the capability reaches 1 bit per pixel.
