SDMI examines hacker data

Nearly one and a half months after the Secure Digital Music Initiative (SDMI) challenged hackers to break the five technologies they are examining to secure music in hardware, the results are in. “Of the five proposed technologies that SDMI still has under consideration, successful attacks were not identified on three technologies, and were identified on two,” said SDMI’s executive director Leonardo Chiariglione.

SDMI’s work is based on the core principles that copyrights should be respected, but that those who wish to use unprotected formats should be able to do so. They received 447 submissions from individuals and teams, each of which has helped SDMI “assess the strengths and weaknesses” of the technologies under consideration. “Of those apparently successful attacks, one of them was not reproduced on additional music samples as part of our evaluation process. The technologies that withstood challenge included both watermark and non-watermark solutions,” added Chiariglione. SDMI had originally posted six technologies but one proponent withdrew its proposal early in the testing process.
