BD+

(Blu-ray Disc Plus) A copy protection system for Blu-ray movies that is called "self-protecting" because each movie studio can devise its own security structure. The Blu-ray disc contains proprietary software that the Blu-ray player with BD+ runs to decrypt certain sections of the disc. Since the disc has an executable program, the software can be periodically updated to counter successful attempts at breaking the system. The BD+ program can also detect a Blu-ray player that has been hacked.

The BD+ method comes from Macrovision, which acquired the technology from Cryptography Research in 2007. It is more sophisticated than Advanced Access Content System (AACS), the first Blu-ray protection system, which is based on keys that are continuously discovered by hackers who uncover the codes from the media player software used to play Blu-ray content on the computer. See AACS and Blu-ray.
