Capacity bounds and constructions for reversible data-hiding [PDF]

open access: yes2002 14th International Conference on Digital Signal Processing Proceedings. DSP 2002 (Cat. No.02TH8628), 2003
An 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.

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

A Reversible Data Hiding Scheme for HEVC

2017 10th International Symposium on Computational Intelligence and Design (ISCID), 2017
Many reversible data hiding schemes using quantized DCT coefficient have been proposed recently. But the big problem was most of schemes could not meet the requirement of visual quality and robustness at the same time. This paper presents a reversible data hiding scheme for HEVC (High Efficiency Video Coding).

Reversible Data Hiding for Video

2018
Difference expansion (DE) and histogram modification (HM) are efficient ways for reversible data hiding (RDH) into digital video. In most occasions, the reversibility of an algorithm cannot be confirmed until the data extracting experiments have been carried out, it means the design of a reversible data hiding algorithm lacks theoretical guidance.

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.

Reversible Data Hiding Scheme for Video

International Journal of Information Security and Privacy, 2019
With the exponential progression in communication technology, advanced mixed media content such as image, sound and video can be effectively duplicated and put away effortlessly without any loss in their original content. Therefore, it is distinctly critical to beat this and the need of a reasonable sort of copyright insurance framework inside the data.

CNN Prediction Based Reversible Data Hiding

IEEE Signal Processing Letters, 2021
How to predict images is an important issue in the reversible data hiding (RDH) community. In this letter, we propose a novel CNN-based prediction approach by luminously dividing a grayscale image into two sets and applying one set to predict the other set for data embedding. The proposed CNN predictor is a lightweight and computation-efficient network

Reversible Data Hiding in JPEG Images

IEEE Transactions on Circuits and Systems for Video Technology, 2016
Among various digital image formats used in daily life, the Joint Photographic Experts Group (JPEG) is the most popular. Therefore, reversible data hiding (RDH) in JPEG images is important and useful for many applications such as archive management and image authentication.
