Efficient reversible data hiding in encrypted images
Journal of Visual Communication and Image Representation, 2014This 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, 2010Due 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 in Encrypted Image
IEEE Signal Processing Letters, 2011This work proposes a novel reversible data hiding scheme for encrypted image. After encrypting the entire data of an uncompressed image by a stream cipher, the additional data can be embedded into the image by modifying a small proportion of encrypted data.

Reversible Data Hiding for JPEG Based on EMD
2012 Seventh Asia Joint Conference on Information Security, 2012To 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.

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.

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 ...

Information Protection and Recovery with Reversible Data Hiding
Third International Conference on Intelligent Information Hiding and Multimedia Signal Processing (IIH-MSP 2007), 2007We propose an effective scheme for protecting and recovering sensitive information based on reversible data hiding techniques in this paper. It is commonly seen that confidential information within an image is deliberately removed, marked or mosaicked before being delivered to the public, including displaying the marked images on the TV screens or ...

Capacity bounds and constructions for reversible data-hiding
2002 14th International Conference on Digital Signal Processing Proceedings. DSP 2002 (Cat. No.02TH8628), 2003An undesirable side effect of many watermarking and data-hiding schemes is that the host signal into which auxiliary data is embedded is distorted. Finding an optimal balance between the amount of information embedded and the induced distortion is therefore an active field of research.

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.
