Statement Regarding the SDMI Challenge
The Secure Digital Music Initiative (SDMI) is developing a
comprehensive system to prevent music piracy. Central to this system
is watermarking, in which an inaudible message is hidden in music to
provide copyright information to devices like MP3 players and
recorders. Devices may then refuse to make copies of pieces of music,
depending on the meaning of the watermark contained therein.
In September 2000, SDMI issued a public challenge to help them choose
among four proposed watermarking technologies. During the three-week
challenge, researchers could download samples of watermarked music,
and were invited to attempt to remove the secret copyright
watermarks.
During the challenge period, our team of researchers, from Princeton
University, Rice University, and Xerox, successfully defeated all
four of the watermarking challenges, by rendering the watermarks
undetectable without significantly degrading the audio quality of the
samples. Our success on these challenges was confirmed by SDMI's
email server.
We are currently preparing a technical report describing our findings
regarding the four watermarking challenges, and the two other
miscellaneous challenges, in more detail. The technical report will
be available some time in November.
This statement, a Frequently Asked Questions document, the full
technical report (when it is ready), and other related information
can be found on the Web at http://www.cs.princeton.edu/sip/sdmi.
