A near reversible image watermarking algorithm

2010 International Conference on Machine Learning and Cybernetics, 2010
Being a novel category of watermarking schemes, reversible watermarking algorithms were developed in recent years. As it can recover the watermarked data back to the original host signal, reversible watermarking algorithms are suitable for medical, military and other special fields. However, these algorithms have their defects, such as weak robustness,

Reversible Audio Watermarking

2017
This section introduces the reversible audio watermarking (RAW) techniques. RAW can be classified according to how the inherent redundancies in the audio signals are utilized. Three types of redundancies and the corresponding RAW algorithms are reviewed. The companding (compression and expansion) approach employs the redundancy in representing a single

Reversible Watermarking by Coefficient Adjustment Method

2010 Sixth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2010
In this paper, a novel reversible watermarking method based on the coefficient adjustment technique is proposed. A host image is first decomposed into the integer wavelet transform (IWT) domain. Subsequently, a secret message is embedded into the low-high (LH), high-low (HL), and high-high (HH) sub-bands of the IWT using the coefficient adjustment ...

Reversible transformations may improve the quality of reversible watermarking

SPIE Proceedings, 2010
We investigate the use of reversible pre-embedding transformations to enhance reversible watermarking schemes for images. We are motivated by the observation that a (non-reversible) sorting transformation dramatically increases the quality of the embedding when combined with a reversible watermark based on a generalized integer transform.

Adaptive Robust Reversible Watermarking Scheme

2018
Digital watermarking technology in the field of information hiding technology has become an important means to protect copyright in network transmission. Robust reversible digital watermarking has been studied for many years as a more adaptive technique for network lossy transmission environment.

A Reversible Watermarking Scheme for 3D Meshes

2009
Reversible watermarking is suitable for hiding data in 3D meshes, because it can remove the embedding-induced distortions after extracting the hidden bits. This paper proposes a novel reversible watermarking scheme based on the difference expansion and the difference shifting.
