In this paper, the authors present a unique method of reversible data hiding separately in encrypted image. This paper presents a new method that combines image cryptography, data hiding and LSB compressing technique for reversible data hiding separately. In this paper, they encrypt the original image with stream cipher algorithm. Then, a data-hider may compress the least significant bits of the encrypted image using a data-hiding key to create a sparse space to accommodate some additional data.
