Data hiding, also known as information hiding, plays an important role in information security
for various purposes. Reversible data hiding is a technique that allows distortion-free …

There have been discussed several data hiding techniques which can hide the secret data
in an image. However, after extracting the secret data some of the image information gets …

Reversible data hiding is a technique that can restore the original cover image without any
distortion after the embedded secret message is extracted. In this paper, a novel reversible …

There have been discussed various data hiding methods which can embed the secret data
in an image. However, the image gets destroyed after extraction of the secret data at the …

Reversible data hiding can restore the original image from the stego image without any
distortion after the embedded secret message is exactly extracted. In this paper, a novel …

This paper presents a reversible data hiding scheme. The proposed scheme is based on the
difference histogram shifting to spare space for data hiding. Nine basic scan paths are …

Reversible data hiding is a data-hiding technique which has the ability to recover the
original version from stego-images after the secret information is extracted. In this paper, we …

In this paper, we propose a new reversible data hiding scheme that uses pixel value
adjusting feature. It has two phases. In first phase, It scans the image diagonally from left to …

This paper proposes a novel reversible data hiding scheme based on the histogram-shifting-
imitated approach. Instead of utilizing the peak point of an image histogram, the proposed …

A reversible data hiding method allows recovery of the cover image after the secret data
have been extracted. In this paper, a novel reversible data hiding method is proposed using …
