Digital Watermarking of Audio Signals for Robust Hidden Audio Communication via Air Audio Channel

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...

Digital 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...

Digital Audio Watermarking Techniques for MP3 Audio Files

Nowadays, a vast amount of information concerning all aspects of human activity is digitised with the goal of profit. One of the most prominent examples is the music industry that now markets audio data mainly in the form of MPEG Audio Layer 3 files rather than on CDs or DVDs. The MP3 audio files are distributed as digital files through various communication means and can easily be copied and r...

Robust spread-spectrum audio watermarking

We present several mechanisms that enable effective spreadspectrum audio watermarking systems: prevention against detection desynchronization, cepstrum filtering, and chess watermarks. We have incorporated those techniques them into a system capable of reliably detecting a watermark in an audio clip that has been modified using a composition of attacks that degrade the original audio characteri...
