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 …

Continuous technological progressions and huge investments are made for the realization
of the various goals in the Internet of Things (IoT) driven networks. Internet of Medical Things …

Prediction-error expansion (PEE) is the most widely investigated reversible data hiding
(RDH) framework. However, the performance of PEE can be further improved since the …

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 …

Pixel-value-ordering (PVO) is one of the most popular methods in reversible data hiding
(RDH). In PVO based methods, pixels are processed in a block-wise way, so that the local …

In the previous multiple histograms modification (MHM) based reversible data hiding (RDH)
method, the prediction-error histograms are generated by a fixed manner, which may …

In this paper, we propose a lossless robust watermarking method by using the polar
harmonic transform with reversible and robust watermarking techniques. Firstly, a new …

Among various techniques of reversible data hiding (RDH), histogram modification has been
mostly investigated and used in practice. Recently, a new histogram modification technique …

Researchers have scrutinized data hiding schemes in recent years. Data hiding in standard
images works well, but does not provide satisfactory results in distortion-sensitive medical …

The data hiding method embeds the data into covers such as video, audio, and images,
which are used for integrity authentication, media protection, communication covert …
