20080291801 | Record Carrier with Copy Protection Means - In summary, ROM marks (such as wobbles, lateral deviations in the spiral with lands and pits in an optical disc) are used on optical media to ensure consumer-grade copying devices cannot duplicate original media. An additional level of security is that the detection of the side channel information requires knowledge of a certain secret, which must be hidden well in authorized players. If the secret leaks, a professional pirate will be able to detect the ROM mark and duplicate the original medium with the side channel information intact. The present invention proposes that instead of a single ROM mark, many ROM marks are applied to a disc. Further, devices are divided into groups, and each group has the capability to only detect one mark from the group. This way, if a secret is obtained from a device, the disc can be duplicated, but only a limited number of devices will be able to use this disc. Creating a disc that can be played in any device requires the hacking of one device from every group. | 11-27-2008 |
