Reversible data hiding in encrypted image (RDHEI) is a technique that can be adopted by
cloud sever to embed additional data into the encrypted image with no permanent distortion …

New security threats are generated with the coming of information industrial 5.0 represented
by artificial intelligence and Industrial Internet of Things (IIoT). One of the most significant …

Recently, various efficient reversible data-hiding schemes based on pixel value ordering
have been proposed for embedding messages into high-fidelity images. In these schemes …

The cover image is generally encrypted by a stream cipher in existing reversible data hiding
in encrypted image (RDHEI) methods. As pixel correlation is seriously damaged, more than …

In this article, a novel sensitive encryption scheme to secure the digital images based on the
Zaslavsky chaotic map is proposed. We employ the Zaslavsky chaotic map as a pseudo …

In this paper, the problem of outsourcing the selective encryption of a medical image to
cloud by resource-constrained devices such as smart phone is addressed, without revealing …

Wireless capsule endoscopy (WCE) has several benefits over traditional endoscopy such as
its portability and ease of usage, particularly for remote internet of things (IoT)-assisted …

A novel joint image coding and reversible data hiding method for vector quantization (VQ)
compressed images is proposed in this paper. Since the original VQ indices often exhibit …

Since the COVID-19 outbreak, there's been a growing need for contactless healthcare to
meet medical diagnosis demands. Electronic health systems using the Internet of Things …

This paper proposes a joint coding and reversible data hiding method for absolute moment
