The data communication is becoming more and more rapidly and conveniently due to the
information technology and Internet expeditious development. Therefore, the protections of …

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 …

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 …

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 …

To consider both hiding payload and stego-image quality, a reversible data hiding scheme
is proposed in this work. The prediction error of each block of size 2× 2 pixels is firstly …

Recently, the reversible data hiding has become a hot research topic. Its major characteristic
is that allows an original image to be completely reconstructed from the stego-image after …

Reversible data hiding based on prediction methods is a data hiding technique wherein
secret bits can be efficiently hidden into cover images. In this paper, we propose a reversible …

Data hiding in digital images can be used in secure communication, copyright protection,
and etc. For some important images, such as medical and military images, the original …

A reversible data hiding method is widely used in medical application and military
application which do not allow distortion of image after data extraction. Conventional method …

The dual stego images based on data hiding has become popular in recent days. Since the
embedding rate in dual stego images is very high. This paper proposes a new data …
