Reversible data embedding is a very important issue, especially in dealing with sensitive
images such as military data and medical data. Based on the edge-directed prediction …

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 …

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 …

To enhance the embedding capacity of a reversible data hiding system, in this paper, a
novel multiple-base lossless scheme based on JPEG-LS pixel value prediction and …

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 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 …

In this paper, a reversible data hiding scheme for digital images with high hiding capacity is
proposed. Original image is segmented into smooth and rough regions based on local …

This paper presents a lossless data hiding scheme. The proposed scheme is based on the
pixel difference histogram shifting to spare space for data hiding. Pixel differences are …

This paper proposes an improved reversible data hiding technique by utilizing Lukac, Feng,
and Fan׳ s expanding method. The scheme uses standard deviation to analyze the …

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 …
