This week two research teams, one from Xerox's Palo Alto research center and one from Princeton and Rice universities, have claimed that they've cracked SDMI's watermark copy protection.
SDMI in other hand denies the claims and says that no one hasn't achieved to crack the protections totally.
The team of universities says that they've successfully cracked the SDMI's watermark technology, but they couldn't verify were they actually able to crack two other copy protection methods, not related to watermarking-technology. This was due SDMI's verification server for these two methods wasn't functioning correctly.
