The ever-growing numbers of medical digital images and the need to share them among
specialists and hospitals for better and more accurate diagnosis require that patients' privacy …

An overview of reversible watermarking techniques appeared in literature during the last five
years approximately is presented in this paper. In addition to this a general classification of …

Over the past few years a number of research papers about reversible watermarks has been
produced. Reversible watermarking is a novel category of watermarking schemes. It not only …

A reversible watermarking scheme for relational databases is proposed in this paper to
achieve lossless and exact authentication of relational databases via expansion on data …

This paper proposes a reversible data hiding scheme for gray-level images. The scheme
exploits the similarity among adjacent pixels and uses the side-match predictors to obtain …

The paper focuses on the VLSI-based digital design and implementation of reversible image
watermarking (RIW) architecture using difference expansion (DE). Mathematical simplicity of …

This paper analyses and rectifies the shortcomings of reversible contrast mapping (RCM)
algorithm for invisible watermarking. The proposed corrected RCM algorithm is tested by …

Reversible data hiding in encrypted images (RDH-EI) has got some promising applications
in cloud storage, medical imaging, forensics etc. It has gained considerable research …

This paper proposed an image steganography method based on integer DCT and affine
transformation. Integer DCT is an appropriate domain for steganography because it is …

Nowadays, digital watermarking algorithms are widely applied to ownership protection and
tampering detection of digital images. In this paper, a new reversible watermarking algorithm …
