Reversible data hiding (RDH) has developed various theories and algorithms since the
early 1990s. The existing works involve a large amount of specialized knowledge, making it …

Reversible data hiding generally exploits the redundancy of the cover medium and
prediction-error expansion (PEE) has become the most effective mechanism. However …

Reversible data hiding (RDH), also known as lossless data hiding, ensures the losslessly
recovery of both the cover medium and the secret message at the decoder. For the video …

The existing reversible data hiding (RDH) methods based on improved pixel value ordering
(IPVO) use only a small portion of the pixels (eg, at most six pixels) in a block for embedding …

Cover-lossless robust watermarking is a new research issue in the information hiding
community, which can restore the cover image completely in case of no attacks. Most …

In the field of reversible data hiding (RDH), how to predict an image and embed a message
into the image with smaller distortion are two important aspects. In this paper, we propose a …

Pixel-value-ordering (PVO) is an efficient technique of reversible data hiding (RDH). By
PVO, the maximum and minimum in each cover image block are first predicted and then …

An effective error prediction algorithm is the key to improving the embedding performance of
reversible data hiding schemes. In this paper, high-performance ridge regression predictor …

Robust reversible data hiding (RRDH) prevents the hidden secret information from
unintentional modifications. This paper presents a novel RRDH scheme based on two-layer …

Reversible data hiding (RDH) is an important topic of data hiding. In this paper, we exploit
pixel-based pixel value ordering prediction (PPVO) and pairwise prediction-error expansion …
