A Hybrid Reversible Data Hiding for Multiple Images With High Embedding Capacity

Abstract

This paper proposed a high capacity reversible data hiding (RDH) scheme using three steganographic images, on which three successive embedding phases are performed. An embedding rule is elaborately designed to guide the data embedding and three alike stego-images are generated in the first phase. In view of the similarity of three stego-images, the pixel value ordering (PVO) strategy is utilized in the second phase. In the third phase, the prediction error histogram shifting (PEHS) strategy is employed by exploiting the slight difference among three temporary stego-images. Since no complex operation is involved, the algorithm is efficient. The experimental results verify that our method is superior to other schemes in both EC and image quality. Moreover, the proposed scheme can successfully resist the RS steganalysis and provide a secure secret transmission.
