BD+

BD+ is a component of the Blu-ray Disc digital rights management system. It was developed by Cryptography Research Inc. and is based on their Self-Protecting Digital Content concept. Its intent was to prevent unauthorized copies of Blu-ray discs and the playback of Blu-ray media using unauthorized devices. While BD+ has not stemmed the flow of "cracked" high-definition content, it has made it necessary for those who wish to copy Blu-ray movies to reinvest resources to break each new version of security code.
