Laplacian: Reversible Data Hiding Technique

2019 Fifth International Conference on Image Information Processing (ICIIP), 2019
Reversible Data Hiding (RDH) techniques are becoming more important in the present era of digital content security. In RDH the reciprocal nature of embedding capacity and visual quality parameters, hinder further visual quality enhancement. The trade-off between embedding capacity and visual quality is an essential characteristic of any data hiding ...

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.

PVO-Based Reversible Data Hiding Using Global Sorting and Fixed 2D Mapping Modification

IEEE transactions on circuits and systems for video technology (Print)
Pixel-value-ordering (PVO) is one of the most popular methods in reversible data hiding (RDH). In PVO based methods, pixels are processed in a block-wise way, so that the local similarities of the images are considered but the global statistical ...

Reversibility improved lossless data hiding

Signal Processing, 2009
Recently, lossless data hiding has attracted increasing interests. As a reversible watermark scheme, the host media and hidden data should be recovered without distortion. A latest lossless data hiding technique based on image blocking and block classification has achieved good performance for image authentication.

Progressive Histogram Modification for JPEG Reversible Data Hiding

IEEE transactions on circuits and systems for video technology (Print)
With the development of social network, a large number of private JPEG images are stored in social cloud platform. Correspondingly, the platform embeds user ID or authentication labels to manage these privacy images, preventing them from being ...

Multi-resolution reversible data hiding

2014 7th International Congress on Image and Signal Processing, 2014
Image reversible data hiding is the process of embedding information in an image in a visually imperceptible way with the result that both the original image and the embedded information can be exactly recovered. In the traditional approaches of histogram shifting and causal window-based difference/prediction-error expansion, pixel value prediction ...

Reversible Data Hiding in Encrypted Images using Chunk Encryption and Redundancy Matrix Representation

IEEE Transactions on Dependable and Secure Computing, 2022
For reversible data hiding in encrypted images (RDHEI), the private information in the original image content is protected and the embedded secret data can be used to manage the encrypted image.
