Hybrid Blind Audio Watermarking for Proprietary Protection, Tamper Proofing, and Self-Recovery
IEEE Access, 2019 The paper presents a lifting wavelet transform (LWT)-based framework for multi-purpose blind audio watermarking. The proposed schemes can be used to carry out robust watermarking for intellectual property protection as well as fragile watermarking for ...

A fragile watermarking scheme for 3D meshes [PDF]
Proceedings of the 7th workshop on Multimedia and security, 2005 In this paper, we propose a new fragile watermarking scheme for 3D meshes. Firstly, the watermark information is adaptively embedded into the mesh geometry by slightly adjusting the vertex positions while the mesh topology is unchanged. The embedded watermark can be blindly retrieved with some priori knowledge and used to authenticate the integrity of ...

Reversible watermarking scheme with image-independent embedding capacity [PDF]
, 2005 Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,

Self-Embedding Fragile Watermarking Scheme to Detect Image Tampering Using AMBTC and OPAP Approaches
Applied Sciences, 2021 Research on self-embedding watermarks is being actively conducted to solve personal privacy and copyright problems by image attack. In this paper, we propose a self-embedded watermarking technique based on Absolute Moment Block Truncation Coding (AMBTC ...

The Scientific World Journal, 2013 We put forward a fragile zero watermarking scheme to detect and characterize malicious modifications made to a database relation. Most of the existing watermarking schemes for relational databases introduce intentional errors or permanent distortions as ...

Fragile Watermarking of 3D Models in a Transformed Domain [PDF]
Applied Sciences, 2020 This paper presents an algorithm aimed at the integrity protection of 3D models represented as a set of vertices and polygons. The proposed method defines a procedure to perform a fragile watermarking of the vertices’ data, namely 3D coordinates and polygons, introducing a very small error in the vertices’ coordinates.

Applying interest operators in semi-fragile video watermarking
, 2022 S.353-362In this article we present a semi-fragile watermarking scheme for authenticating intra-coded frames in compressed digital videos. The scheme provides the detection of content-changing manipulations while being moderately robust against content ...

A Self-Recovery Fragile Image Watermarking with Variable Watermark Capacity
Applied Sciences, 2018 Currently, the watermark capacity of most self-recovery fragile image watermarking schemes is fixed. That means for smooth regions and texture regions, the length of watermark information is always the same. However, it is impractical since more recovery
