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 …

Reversible data hiding in encrypted images has attracted considerable attention from the
communities of privacy security and protection. The success of the previous methods in this …

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 proposes a novel scheme of reversible data hiding in encrypted images using
distributed source coding. After the original image is encrypted by the content owner using a …

This paper proposes lossless, reversible, and combined data hiding schemes for ciphertext
images encrypted by public-key cryptosystems with probabilistic and homomorphic …

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 …

In the past more than one decade, hundreds of reversible data hiding (RDH) algorithms
have been reported. Via exploring the correlation between the neighboring pixels (or …

To protect image contents, most existing encryption algorithms are designed to transform an
original image into a texture-like or noise-like image which is, however, an obvious visual …
