Recently, more and more attention is paid to Reversible Data Hiding (RDH) in encrypted images, since it maintains the excellent property that the original image cover can be losslessly recovered after which is embedded is extracted while protecting the image content's as confidential. All methods used previously embed data by reversibly vacating room from the images which are been encrypted, which may cause some errors on data extraction and/or image restoration. In this paper, the authors propose a novel method by reserving room before encryption with a traditional RDH algorithm and thus it becomes easy for the data hider to reversibly embed data in the encrypted image.
