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 ...

Reversible data hiding in encrypted AMBTC images
Multimedia Tools and Applications, 2017Signal processing in the encrypted domain has attracted a lot of attention due to the requirement for content security and privacy protection. Reversible data hiding in encrypted images (RDH-EI) is also a hot topic. However, the majority of the published techniques are designed for uncompressed images rather than JPEG-, VQ- and BTC-compressed images ...

A Reversible Data Hiding Scheme for JPEG Images
2010When 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, 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 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.

Reversible Data Hiding in Pairwisely Encrypted Images
2016 Third International Conference on Computing Measurement Control and Sensor Network (CMCSN), 2016This work proposes a novel separable method for encrypted images. The input image is encrypted first via a pairwise encryption scheme. Then the data bits can be embedded into the pairwisely encrypted image by the well-known difference-expansion technique.

An improved reversible data hiding in encrypted images
2015 IEEE China Summit and International Conference on Signal and Information Processing (ChinaSIP), 2015This paper is an improved version of Zhang's reversibility improved data hiding method in encrypted images. The original work randomly selects p%(0 < p ≤ 20) pixels from an original image to obtain the estimation error for secret data embedding. In this work, we estimate half of the pixels in the original image to obtain the estimation error so that ...

Capacity-Approaching Codes for Reversible Data Hiding
2011By 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.
