Singular-Spectrum Analysis for Digital Audio Watermarking with Automatic Parameterization and Parameter Estimation

Singular-Spectrum Analysis for Digital Audio Watermarking with Automatic Parameterization and Parameter Estimation

This paper proposes a blind, inaudible, robust digitalaudio watermarking scheme based on singular-spectrum analysis, which relates to watermarking techniques based on singular value decomposition. We decompose a host signal into its oscillatory components and modify amplitudes of some of those components with respect to a watermark bit and embedding rule. To improve the sound quality of a water...

Spread Spectrum for Digital Audio Watermarking

The increase in computational power and the proliferation of the Internet, witnessed over the last decade, have facilitated the production and distribution of unauthorized copies of copyrighted multimedia information. It is now easy to make a perfect digital illegal copy and distribute it overnight to millions of people via the Internet, resulting in large revenue loses to the movie and record ...

Iterative Decoding and Estimation for Digital Audio Watermarking

In this paper, a novel blind audio watermarking method is investigated. In this approach, the watermarking message is embedded into the low frequency components of the host signal in a novel transformation named Point to Point Graph (PPG). This watermarking scheme does not make significant high frequency components, and leads to a suitable blind dewatermarking procedure based on nonuniform samp...

Robust and efficient digital audio watermarking using audio content analysis

Digital Audio Watermarking: Survey

Digital audio watermarking is a technique for embedding additional data along with audio signal. Embedded data is used for copyright owner identification. A number of audio watermarking techniques are proposed. These techniques exploit different ways in order to embed a robust watermark and to maintain the original audio signal fidelity. This paper makes a tutorial in general digital watermarki...
