There is also an amount of works on data hiding in the encrypted field. Most of the work on reversible data hiding focuses on the data embedding or extracting on the plain spatial domain. This paper by reserving room prior to encryption with a traditional RDH algorithm, and thus it is simple the data hider to reversibly embed data in the encrypted image. The proposed paper can attain real reversibility, that is, data extraction and image revival are free of any fault. Thus, the data hider can advantage from the extra space emptied out in preceding stage to make data hiding process unforced.
