Power-spectrum condition for energy-efficient watermarking
This paper presents a model for watermarking and some attacks on watermarks. Given the watermarked signal, the so-called Wiener attack performs minimum mean-squared error (MMSE) es...

Perceptual Copyright Protection Using Multiresolution Wavelet-Based Watermarking And Fuzzy Logic
In this paper, an efficiently DWT-based watermarking technique is proposed to embed signatures in images to attest the owner identification and discourage the unauthorized copying...

Watermarking 3D Polygonal Meshes Using the Singular Spectrum Analysis
Watermarking is to embed a structure called a watermark into the target data such as images. The watermark can be used, for example, in order to secure the copyright and detect tam...

A Digital Image Processing and Database System for Watermarks in Medieval Manuscripts
Watermarks are the most important tool for dating old, not explicitly dated paper documents. Hence, catalogues and databases of watermarks play an eminent role for the work of med...

Watermarking 3D Polygonal Meshes in the Mesh Spectral Domain
Digital watermarking embeds a structure called watermark into the target data, such as image and 3D polygonal models. The watermark can be used, for example, to enforce copyright ...

Robust Covert Communication over a Public Audio Channel Using Spread Spectrum
We present a set of watermarking techniques for effective covert communication over an audio signal carrier. Watermark robustness is enabled using: (i) redundant spread-spectrum fo...

Threading Software Watermarks
We introduce a new dynamic technique for embedding robust software watermarks into a software program using thread contention. We show the technique to be resilient to many semanti...

A scene-based video watermarking technique using SVMs
In this paper we present a scene-based video watermarking scheme using support vector machines (SVMs). In a given scene, the algorithm uses the first h′ frames to train an embed...
