In this study, the authors introduce a highly efficient reversible data hiding system. It is based
on dividing the image into tiles and shifting the histograms of each image tile between its …

This paper proposes a novel reversible data hiding method in encrypted images based on
specific encryption process. In the proposed specific encryption algorithm, the stream cipher …

Unlike histogram-based reversible data hiding (RDH), the general distortion-based
framework considers pixel-by-pixel distortions, which is a new research direction in RDH …

In the past two decades, reversible data hiding (RDH), also referred to as lossless or
invertible data hiding, has gradually become a very active research area in the field of data …

Medical images carry a lot of important information for making a medical diagnosis. Since
the medical images need to be communicated frequently to allow timely and accurate …

E-healthcare framework requires transfer of patient report to a specialist in a real time
framework. Subsequently, any damage to patient information can prompt a wrong diagnosis …

Reversible Data Hiding in Encrypted Image (RDHEI) is a technology for embedding secret
information in an encrypted image. It allows the extraction of secret information and lossless …

This paper proposes a reversible data hiding scheme for gray level images. It exploits the
high correlation among image block pixels to produce a difference histogram. Secret data is …

In this paper, we propose a novel reversible data hiding in encrypted images (RDH-EI)
method that achieves the highest hiding capacity in the RDH-EI research field and full …

In this paper, a secure watermarking framework based on Discrete Cosine Transform (DCT)
for embedding a color watermark into digital images that provides robustness against JPEG …
