In recent years, dual-image techniques have been widely used in reversible data hiding.
Most data hiding methods focus on finding the best predictive value to reduce the degree of …

This work presents a novel reversible data hiding scheme based on combinations of pixel
orientations located at two steganographic images to enhance embedding capacity and …

Compared to conventional reversible data hiding (RDH) methods, the dual-image RDH
technique is an effective way to achieve greater embedding rate and better quality of the …

Dual-image reversible data hiding (RDH) technology has been an active research area and
became an essential part of information security because of its unique advantages in …

Reversible data hiding (RDH) subtly alter the cover image for embedding the secret data,
after extracting the secret data, the cover image can also be completely restored. In this …

In this paper, we propose a new dual-image based reversible data hiding scheme through
(7, 4) Hamming code (RDHHC) using shared secret key. A block of seven pixels are …

Reversible data hiding (RDH) algorithms are concerned with concealing data within images
such that the original image can be fully recovered upon the extraction of hidden data. A …

Watermarking scheme is an efficient solution to protect the multimedia document from
unauthorized modification. Several watermarking scheme have been developed but …

Reversible data hiding methods can embed secret data into multimedia to prevent attacks
from hackers. Reversible data hiding methods based on multiple stego-images have been …

In this paper, we proposed dual image based reversible data hiding scheme using three
pixel value difference and difference expansion. We take consecutive three pixels from …
