Now-a-days, more and more interest is paid to Reversible Data Hiding (RDH) in encrypted images, since it maintains the excellent property that the original image can be lossless recovered after embedded data is extracted while protecting the image content's privacy. Unlike previous methods, a Novel method is proposed by reserving room before encryption with a traditional RDH algorithm, so that it is easy for the data hider to reversibly embed the secret data in the encrypted image. The proposed method can achieve real reversibility i.e., data extraction and image recovery are free of any error.
