Abstract: There are many invalid modifications of pixels in traditional reversible image information hiding algorithms based on asymmetric histogram modification. To solve this problem, a reversible information hiding scheme based on multi-pair asymmetric prediction error histogram modification is proposed in this paper. This scheme combines the advantages of asymmetric histogram modification algorithm and the characteristics of multihistogram modification algorithm, and selects the smooth region of the image to modify the asymmetric histogram for embedding information. At the same time of achieving the compensation reduction effect of asymmetric histogram, it can further reduce the invalid pixel modification and improve the rate distortion performance.
