Audio Watermarking and Fingerprinting: For Which Applications?

Leandro de C.T. Gomes, Pedro Cano, Emilia G�mez, Madeleine Bonnet, Eloi Batlle
2003 Journal of New Music Research  
In association with a database, this fingerprint can be used to identify a recording, which is useful, for example, to monitor audio excerpts played by broadcasters and webcasters.  ...  Watermarking has been proposed as a solution to this problem. It consists in embedding into the audio signal an inaudible mark containing copyright information.  ...  Acknowledgments The authors would like to thank Nicolas Moreau and Lazar Bibin for their participation in the research on audio watermarking described in this article.

Audio watermarking for live performance

Ryuki Tachibana, Edward J. Delp III, Ping W. Wong
2003 Security and Watermarking of Multimedia Contents V  
Audio watermarking has been used mainly for digitally stored content. Using real-time watermark embedding, its coverage can be extended to live broadcasts and live performances.  ...  To solve these problems, we propose a watermark generation algorithm that outputs only a WS, and a system composition method in which a mixer outside the computer mixes the WS generated by the algorithm  ...  Though it is true that these purposes have greatly encouraged audio watermarking research so far, audio watermarking is not a technology useful only for digitally stored music.  ...
