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 …

Steganography and steganalysis are the prominent research fields in information hiding
paradigm. Steganography is the science of invisible communication while steganalysis is …

Prediction-error expansion (PEE) is the most successful reversible data hiding (RDH)
technique, and existing PEE-based RDH methods are mainly based on the modification of …

Reversible data embedding has drawn lots of interest recently. Being reversible, the original
digital content can be completely restored. We present a novel reversible data-embedding …

A novel reversible data hiding algorithm, which can recover the original image without any
distortion from the marked image after the hidden data have been extracted, is presented in …

Digital audio, video, images, and documents are flying through cyberspace to their
respective owners. Unfortunately, along the way, individuals may choose to intervene and …

Reversible watermarking enables the embedding of useful information in a host signal
without any loss of host information. Tian's difference-expansion technique is a high …

We present a novel lossless (reversible) data-embedding technique, which enables the
exact recovery of the original host signal upon extraction of the embedded information. A …

A reversible watermarking algorithm with very high data-hiding capacity has been
developed for color images. The algorithm allows the watermarking process to be reversed …

The unique stature of photographs as a definitive recording of events is being diminished
due, in part, to the ease with which digital images can be manipulated and altered. Although …
