Separable Reversible Data Hiding in Encrypted Image

IEEE Transactions on Information Forensics and Security, 2012
This work proposes a novel scheme for separable reversible data hiding in encrypted images. In the first phase, a content owner encrypts the original uncompressed image using an encryption key. Then, a data-hider may compress the least significant bits of the encrypted image using a data-hiding key to create a sparse space to accommodate some ...

Reversible data hiding

IEEE Transactions on Circuits and Systems for Video Technology, 2003
A novel reversible data hiding algorithm, which can recover the original image without any distortion from the marked image after the hidden data have been extracted, is presented in this paper. This algorithm utilizes the zero or the minimum points of the histogram of an image and slightly modifies the pixel grayscale values to embed data into the ...

Reversible data hiding in adjacent zeros

Multimedia Systems, 2021
Data hiding techniques are used to embed information into digital objects for the purpose of copyright protection, covert communication, media notation, among other applications. Compared with traditional data hiding techniques, reversible data hiding (RDH) can restore the original digital object after extracting the hidden data.

High-Performance Reversible Data Hiding

Fundamenta Informaticae, 2008
This paper proposes a high-performance reversible data hiding algorithm based on the block difference histogram of a cover image. If a message is to be embedded into an image, the difference of the block at the maximum point is increased by 1 or left unchanged if the message bit is "1" or "0", respectively.

Steganalysis for Reversible Data Hiding

2009
In recent years, several lossless data hiding techniques have been proposed for images. Lossless data embedding can take place in the spatial domain or in the transform domain. They utilized characteristics of the difference image or the transform coefficient histogram and modify these values slightly to embed the data. However, after embedding message

Hierarchy-based reversible data hiding

Expert Systems with Applications, 2013
In this paper, we propose a new method for reversible data hiding by employing the hierarchical relationships of original images. There are many parameters for accessing the performances of reversible data hiding algorithms, including the output image quality, the hiding capacity, and the overhead for decoding.
