Steganography is the science and art of covert communication. Conversely, steganalysis is
the study of uncovering the steganographic process. The evolution of steganography has …

This paper proposes a reversible data hiding method for natural images. Due to the
similarity of neighbor pixels' values, most differences between pairs of adjacent pixels are …

Histogram shifting is an effective reversible data hiding (RDH) approach in processing
digital images. When the host image is encrypted for privacy protection in some open …

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 …

There are three problems in the existing reversible data hiding (RDH) algorithms in
encrypted images: one is that some algorithms are not processed in the encrypted domain; …

In data hiding, pixel-value differencing and least significant bit are well-known techniques to
embed secret data. In this paper, a novel data hiding scheme is proposed to provide high …

Data hiding is an important way of realising copyright protection for multimedia. In this study,
a new predictive method is proposed to enhance the histogram-based reversible data hiding …

This paper proposes a digital image reversible data hiding method in integer lifting transform
domain. Owing to the characteristics of the natural image statistics, the neighbor pixel values …

For the past few years, the schemes of data hiding are growing rapidly. Generally, data
hiding performs well on common images but it does not provide satisfying results on …

Digital steganography is the science of establishing hidden communication on electronics;
the aim is to transmit a secret message to a particular recipient using unsuspicious carriers …
