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 …

The leakage of medical audio data in telemedicine seriously violates the privacy of patients.
In order to avoid the leakage of patient information in telemedicine, a two-stage reversible …

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 …

The rapid development of the Industrial Internet of Things (IIoT) and artificial intelligence (AI)
brings new security threats by exposing secret and private data. Thus, information security …

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 …

Reversible data hiding (RDH) has developed various theories and algorithms since the
early 1990s. The existing works involve a large amount of specialized knowledge, making it …

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 …

Reversible data hiding generally exploits the redundancy of the cover medium and
prediction-error expansion (PEE) has become the most effective mechanism. However …

Cover-lossless robust watermarking is a new research issue in the information hiding
community, which can restore the cover image completely in case of no attacks. Most …

In this paper, a novel code division multiplexing (CDM) algorithm-based reversible data
hiding (RDH) scheme is presented. The covert data are denoted by different orthogonal …
