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 …

In the last few years, with the increasing popularity of cloud computing and the availability of
mobile smart devices as well as ubiquitous network connections, more and more users are …

Reversible data hiding in encrypted images (RDHEI) is an effective technique to embed data
in the encrypted domain. An original image is encrypted with a secret key and during or after …

With the development of cloud storage and privacy protection, reversible data hiding in
encrypted images (RDHEI) has attracted increasing attention as a technology that can …

This paper first introduces a parametric binary tree labeling scheme (PBTL) to label image
pixels in two different categories. Using PBTL, a data embedding method (PBTL-DE) is …

Reversible data hiding in encrypted images (RDHEI) is an effective technique of data
security. Most state-of-the-art RDHEI methods do not achieve desirable payload yet. To …

This paper first introduces a binary-block embedding (BBE) method to embed secret data in
a binary image. Using BBE, we propose an algorithm for reversible data hiding in encrypted …

In this paper, we propose a novel reversible data hiding method in encrypted images. The
proposed method takes full advantage of the spatial correlation in the original images to …

With the rapid development of network media, increasing research on reversible
watermarking has focused on improving its robustness to resisting attacks during digital …

Reversible data hiding in encrypted images (RDHEI) can be used as an effective technique
to embed additional data directly in the encrypted domain and therefore, without any …
