Storing and communicating secret and/or private information has become part of our daily
life whether it is for our employment or personal well-being. Therefore, secure storage and …

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 …

In this paper, a novel triple-image encryption and hiding algorithm is proposed by combining
a 2D chaotic system, compressive sensing (CS) and the 3D discrete cosine transform (DCT) …

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 …

In order to safely and covertly protect the digital image information during public channel
transmission and localized storage, a stable image visually secure encryption algorithm by …

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 …

In this paper, an efficient and robust meaningful image encryption (MIE) scheme is
developed by combining block compressive sensing (BCS) and singular value …
