This paper presents a novel reversible data hiding algorithm, which can recover the original image without distortion from the marked image after the hidden data have been extracted. This algorithm utilizes the zero or the minimum point of the histogram and slightly modifies the pixel values to embed data.

Reversible Data Hiding with Hierarchical Relationships
2012In this paper, we propose a new method for reversible data hiding by employing the hierarchical relationships of original images. Considering the ease of implementation and the little overhead needed for decoding, we employ the histogram-based scheme with extensions for reversible data hiding.

Reversible Data Hiding Based on Histogram
2007Recently, the reversible data hiding technology has been discussed extensively. Its major characteristic is that allows an original image to be completely reconstructed from the stego-image after the extraction of the embedded data. 2006, the reversible data hiding based on histogram is proposed by Ni,et al.(NSAS). However, the embedded data can not be

Double-threshold reversible data hiding
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010This proposed scheme reversibly embeds data into image prediction-errors by using histogram-pair method with double thresholds (embedding threshold and fluctuation threshold). The embedding threshold is used to select only those prediction-errors, whose magnitude does not exceed this threshold, for possible reversible data hiding.

Reversible image processing via reversible data hiding
2016 IEEE International Conference on Digital Signal Processing (DSP), 2016Image processing is a very popular and widely used technique. In this paper, we propose a framework for realizing reversible image processing, which enables that the users can return the processed image to the original copy without loss. In the proposed method, the original image is firstly processed to get the desired target image by a classic image ...

Histogram-Based Reversible Data Hiding
2010This paper presents a novel histogram-based reversible data hiding technique to embed secret data into gray-scale host image. This method utilizes the difference of the pixel values of the host image and the zero or the minimum points of the histogram of the difference image and modifies the pixel grayscale values slightly to embed secret data into ...

The chapter presents an application of reversible data hiding for the authentication of image travelling over a hostile and insecure communication channel. The reversible data resides in the image and tracks any changes done to it on a communication channel. The extraction of data and any modification to its structure reveals changes in the image. This

A Reversible Data Hiding Approach to Mesh Authentication
The 2005 IEEE/WIC/ACM International Conference on Web Intelligence (WI'05), 2005This paper proposes a reversible data hiding method to authenticate 3D meshes by modulating the distances from the mesh faces to the mesh centroid to embed a fragile watermark. It keeps the modulation information in the watermarked mesh so that the reversibility of the embedding process is achieved.

Optimal PPVO-based reversible data hiding
Journal of Visual Communication and Image Representation, 2017Abstract The optimal PPVO-based reversible data hiding (RDH) including adaptive prediction pattern and optimal bin selection is proposed in this paper. By reasonably designing the prediction pattern, each to-be-embedded pixel can be predicted by the n ( n ∈ { 4 , … , 13 } ) neighbors surrounding it.

A HDWT-based reversible data hiding method
Journal of Systems and Software, 2009This paper presents a reversible data hiding method which provides a high payload and a high stego-image quality. The proposed method transforms a spatial domain cover image into a frequency domain image using the Haar digital wavelet transform (HDWT) method, compresses the coefficients of the high frequency band by the Huffman (or arithmetic) coding ...
