This work proposes a novel scheme to reversibly hide data into encrypted grayscale image in a separable manner. During the first phase, the content owner encrypts the image by permuting the pixels using the encryption key. The data hider then hides some data into the encrypted image by histogram modification based data hiding, making use of data hiding key. At the receiver side, if the receiver has only encryption key, he can generate an image similar to the original one, but cannot read the… CONTINUE READING
