High-capacity reversible data hiding in encrypted images based on extended run-length coding and block-based MSB plane rearrangement

In this paper, we propose a different scheme which attains real reversibility by reserving room before encryption with a traditional RDH algorithm, and then encrypting the data and embedding the data in the encrypted image, We used some solid encryption techniques which is efficient. We also removed the data hider from the image process. The proposed method can achieve real reversibility that is data extraction and image recoveries are free of any error.
