摘要：This paper aims at proposing a novel method by reserving groom before encryption with atraditionalRDH algorithm. Recently, more and more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be losslessley covered after embedded data is extracted while protecting the image content's confidentiality. All previous methods embed data by reversibly vacating room from the encrypted images, which may be subject to some errors on data extraction and/or image restoration however, the proposed method can achieve real reversibility, that is, data extraction and image recovery are free of any error. MD5 algorithm is used and implemented in order to enhance and provide double layer of data secure mechanisms.
