AB - The Secure Digital Music Initiative is a consortium ofparties interested in preventing piracy of digital music, and to this end they are developing architectures for con- tent protection on untrusted platforms. SDMI recently held a challenge to test the strength of four watermark- ing technologies, and two other security technologies. No documentation explained the implementations of the technologies, and neither watermark embedding nor de- tecting software was directly accessible to challenge par- ticipants. We nevertheless accepted the challenge, and explored the inner workings of the technologies. We re- port on our results here. ER -
