Improving the Security of Reversible Data Hiding Using Multiple Histogram Modification
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 Reversible data hiding (RDH) allows carrying secret information in cover media without introducing permanent distortion. For a RDH method, the important performance measurements are embedding capacity and image quality. Since embedding capacity is an important requirement in the field of data hiding, it is necessary to consider the security of data ...

A novel reversible data hiding based on adaptive block‐partition and payload‐allocation method
IET Image Processing, Volume 15, Issue 2, Page 571-585, 7 February 2021., 2021 Abstract A reversible data hiding method based on partition is researched because it can effectively reduce shifting distortion in given embedding capacity. However, traditional partition is to divide an image into equal‐sized blocks, which cannot be divided reasonably according to the content of the image.

IET Image Processing, Volume 20, Issue 1, January/December 2026.This paper presents a context‐aware dual pixel value ordering (CA‐DPVO) framework for high‐fidelity reversible data hiding. By integrating a variance‐driven block selection model with bidirectional embedding, CA‐DPVO dynamically adapts payload distribution to image content, confining changes to low‐variance regions.

A Clustering‐Based Color Reordering Method for Reversible Data Hiding in Palette Images
IET Image Processing, Volume 19, Issue 1, January/December 2025.This manuscript proposes a clustering‐based color reordering method for reversible data hiding in palette images. The proposed method improves the maximal embedding capacities and the visual quality under the fixed embedding capacities. We conducted experiments on two image datasets and six standard images to verify that the performance improvement of ...
