An undesirable side effect of many water marking and data hiding schemes is that the host signal into which auxiliary data is embedded is distorted. In some applications which hide data into important images, permanent distortion of the image is unacceptable (e.g. X ray images). In these applications, a reversible data hiding method is required. Recently, more attention is paid to Reversible Data Hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content's confidentiality.
