Challenges to Watermarking Continue in Wake of London Tests
The <A HREF="http://www.sdmi.org/">Secure Digital Music Initiative</A> (SDMI) will soon move into Phase II of its evaluation of digital audio watermarking, following listening tests conducted in early July at Sony's Whitfield Street Studios in London and administered by Sony VP of engineering Malcolm Davidson. A soon-to-be-published report from Paul Jessop of the <A HREF="http://www.ifpi.org/">International Federation of Phonograph Industries</A> reveals that the participants in the tests—almost all of them audio-industry professionals or journalists—averaged just slightly better than 50% in their abilities to detect the watermarks.
