Steganography has become a hot topic in information hiding, and the reversibility
technology allows the recovery of the original image without distortion when the embedded …

In this paper, we propose a reversible data hiding method based on prediction and
histogram-shifting (PHS) using Delaunay triangulation and selective embedment. Because …

The stego image quality produced by the histogram-shifting based reversible data hiding
technique is high; however, it often suffers from lower embedding capacity compared to …

As the multimedia and internet technologies are growing fast, the transmission of digital
media plays an important role in communication. The various digital media like audio, video …

Abstract Information hiding is an important method to achieve multi-media security. Recently,
many researchers have paid attention to the reversible data hiding scheme, which can …

In this article, a new reversible data hiding method using most significant bits and center
shifting technique in dual images is proposed. The proposed reversible data hiding method …

Steganography is the technique of embedding secret data to another multimedia type. A
reversible steganography scheme (RSS) uses image features to hide the secret data into the …

In this paper, we proposed methods to accurately predict pixel values by effectively using
local similarity, curved surface characteristics, and edge characteristics present in an image …

Data hiding techniques are very significant in the research area of information security. In
this article, the authors propose a new reversible data hiding (RDH) scheme using …

Reversible data hiding (RDH) algorithms allow data protection and exact recovery of the
original cover image upon data extraction. Most of RDH algorithms attempt to embed data …
