Abstract

A method of reversible data hiding in encrypted images is proposed, in which either data-extraction or image-recovery is applicable to an encrypted image. The proposed method is a reversible data hiding in encrypted image with improved performance. A content owner first encrypts the image by permutation using an encryption key. Then a data-hider may embed data into the encrypted image by difference expansion and shifting. If the receiver has the data-hiding key, he can extract the hiding data. If the receiver has the encryption key, he can decrypt the received image, and get an image similar to the original one. If the receiver has both the data-hiding key and the encryption key, he can extract the additional data and recover the original content without any error. Experimental results demonstrate that the proposed scheme can embed a larger payload into the encrypted image while keeping the same PSNR (peak signal-to-noise ratio).
