Implementation of the DSSS method in watermarking digital audio objects
The paper presents the results of implementation in the Matlab environment for watermarking embedder and extractor based on the Direct Sequence Spread Spectrum (DSSS). A block diagram of watermarking system, an analysis of watermarked signal reproduced as well as watermarking system robustness to degrading factors: lossy compression, signal-to-noise ratio (SNR) as well as a change in sampling f...

متن کاملDigital 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...
متن کاملDigital Blind Audio Watermarking
Digital audio watermarking techniques are widely applied to protect the ownership of digital audio media. This study presents an audio watermarking scheme for audio e-leaning contents. The proposed audio watermarking method can significantly reduce the bit error rates, so enhance the robustness against common attacks. The experimental results under common attacks demonstrate that our watermarki...
متن کاملMethod of Digital-audio Watermarking Based on Cochlear Delay Characteristics
This paper proposes a state-of-the-art method of digital-audio watermarking, based on the properties of the human cochlear. It is based on the concept of embedding inaudible watermarks (e.g., copyright data) into an original sound by controlling the phase characteristics of the sound in relation to the characteristics of cochlear delay. The method involves two processes, i.e., embedding and det...
