Thereare also a number of works on data hiding in the encrypted domain. Thereversible data hiding in encrypted image is investigated in. Most of the workon reversible data hiding focuses on the data embedding/extracting on the plainspatial domain. A content owner encrypts the original image using an encryptionkey, and a data-hider can embed additional data into the encrypted image usinga data-hiding key though he does not know the original content. With anencrypted image containing additional data, a receiver may first decrypt itaccording to the encryption key, and then extract the embedded data and recoverthe original image according to the data-hiding key. In a novel scheme for separable reversible data hiding in encrypted image.In the proposed scheme, the original image is encrypted using an encryption keyand the additional data are embedded into the encrypted image using adata-hiding key.If a receiver has the data-hiding key, he ca
