Abstract Reversible watermarking is a novel category of watermarking schemes. It not only can strengthen the ownership of the original media but also can completely recover the original media from the watermarked media. This feature is suitable for some important media, such as medical and military images, because these kinds of media do not allow any losses. The reversible watermarking schemes should have to give better embedding capacity and higher visual quality in terms of PSNR. The aim of this paper is to define the purpose of reversible watermarking, reflecting recent progress, and provide some research issues in terms of higher embedding capacity without degrading visual quality. Keywords: Difference expansion based method, histogram shifting based method, Interpolation based technique. Full text: https://sites.google.com/site/ijrit1/home/V1I424.pdf
