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 …

Multimedia technology usages is increasing day by day and to provide authorized data and
protecting the secret information from unauthorized use is highly difficult and involves a …

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 …

Prediction-error expansion (PEE) is the most successful reversible data hiding (RDH)
technique, and existing PEE-based RDH methods are mainly based on the modification of …

In prediction-error expansion (PEE) based reversible data hiding, better exploiting image
redundancy usually leads to a superior performance. However, the correlations among …

This paper presents a high-fidelity reversible data hiding scheme for digital images based
on a new prediction strategy called pixel-value-ordering (PVO) and the well-known …

An efficient predictor is crucial for high embedding capacity and low image distortion. In this
letter, a ridge regression-based high precision error prediction algorithm for reversible data …

This paper investigates the use of local prediction in difference expansion reversible
watermarking. For each pixel, a least square predictor is computed on a square block …

Histogram shifting (HS) embedding as a typical reversible data hiding scheme is widely
investigated due to its high quality of stego-image. For HS-based embedding, the selected …

In this paper, based on two-dimensional difference-histogram modification, a novel
reversible data hiding (RDH) scheme is proposed by using difference-pair-mapping (DPM) …
