Reversible data hiding in encrypted images (RDHEI) can serve as a technical solution to
secure data in applications that rely on cloud storage. The key features of an RDHEI scheme …

This paper proposes a new high-capacity reversible data hiding scheme in encrypted
images. The content owner first divides the cover image into blocks. Then, the block …

Reversible data hiding (RDH) is a recent research field of information security for secured
digital data transmission. The advancements in communication technology and the …

The proposed scheme groups three pixels as an embedding unit to conceal three bits of
secret data in which the possible modification for each pixel is at most+ 1 or− 1. With our …

Secret image sharing (SIS) scheme is an important technology to protect secret information.
It distributes the secret data into multiple shares so that the participants can obtain the …

Recently, several reversible information hiding methods based PVO (pixel value ordering)
techniques have been proposed, in these methods, secret data always are embedded in …

QR code is an important means for delivering information which has been widely used in our
daily life. As an ISO international standard, the QR code encoding and decoding process are …

This article first proposes two types of three-dimensional (3D) fractal reference matrices.
Then, a new reversible (2, 3) secret image sharing scheme based on a fractal matrix is …

This paper first proposes a generation algorithm of a stick insect matrix. Then, a novel
reversible secret image sharing scheme based on the stick insect matrix is presented. With …

In this paper, we propose a reversible data hiding scheme for the encrypted images (RDHEI)
based on vector quantization (VQ) prediction and parametric binary tree labeling (PBTL). VQ …
