While both HD DVD and Blu-ray Disc have a layer of copy protection known as Advanced Access Content System (AACS), one company is emphasizing how Blu-ray is safe from BackupHDDVD due to it's extra included Digital Rights Management (DRM). Bit-tech.net has an article up about another layer of protection for Blu-ray, known as BD+.
The article publishes quotes from an email apparently received from Cryptography Research Inc. (CRI), the company responsible for BD+. The company seems to be taking advantage of the reported failure of AACS on HD DVD discs, to emphasize the extra security measures that BD+ offers to those content companies in the Blu-ray camp.
"BD+ is a ground-breaking security technology which is designed to enable HD optical formats to recover from major piracy attacks without revoking players or affecting legitimate users. It is a safe-guard that is only available for studios releasing titles in the Blu-ray disc format. BD+ does not exist for the HD DVD format, and was not compromised in the Muslix64 hack." the email reads.
"A report released by Independent Security Evaluators affirmed that CRI's Self-Protecting Digital Content, the principal architecture behind BD+, significantly enhances the anti-piracy measures in AACS by providing critical format security needs not addressed by AACS alone." it continues.
BackupHDDVD recently got an upgrade to v1.00, adding support for Volume keys to be used.
