A Reversible Data Hiding Scheme for JPEG Images

2010
When JPEG images are used as cover objects for data hiding, many existing techniques require the images to be fully or partially decompressed before embedding. This makes practical application of these methods limited. In this paper, we investigate ways to hide data in the compressed domain directly and efficiently, such that both the original content ...

Efficient reversible data hiding in encrypted images

Journal of Visual Communication and Image Representation, 2014
This paper proposes a novel scheme of reversible data hiding in encrypted images based on lossless compression of encrypted data. In encryption phase, a stream cipher is used to mask the original content. Then, a data hider compresses a part of encrypted data in the cipher-text image using LDPC code, and inserts the compressed data as well as the ...

Adaptive reversible data hiding based on histogram

2010 10th International Conference on Intelligent Systems Design and Applications, 2010
Due to the development of internet rapidly, the secure transmission of information has become more and more importance. Until now, there are many scholars study in the topic of data hiding. Specially, the reversible data hiding scheme catch the researcher's attention.

Reversible Data Hiding for JPEG Based on EMD

2012 Seventh Asia Joint Conference on Information Security, 2012
To save communication bandwidth, data compression method usually is used when the stego-image transmits. To defend data security, the data hiding technology is used in the data communication. However, it seems that there is no relationship between data compression and data hiding. Actually, they are closely related.

Capacity-Approaching Codes for Reversible Data Hiding

2011
By reversible data hiding, the original cover can be losslessly restored after the embedded information is extracted. Kalker and Willems established a rate-distortion model for reversible data hiding, in which they proved the capacity bound and proposed a recursive code construction.
