Même si l'on arrive à dézoner, c'est pas sûr que ça marche pour un nouveau disque contenant un nouveau programme de sécurité BD+.
The BD+ deployment includes three phases:
- Transform code (can be included on any title)
It swaps a part of AV data with separately prepared AV data. For example, such a part of AV data on the disc may be corrupted and will not be useful without corrections with BD+ content code running in the BD+ security VM. This same process can be used for forensic marking purpose, which may be used to identify the source of content that has been illegally distributed.
- Basic Countermeasure (when a hack has been confirmed)
When a hack is suspected, content provider can enter into a hack study. Once a hack is confirmed by the manufacturer of suspected Player, then Content Provider can have developed and release BD+ Content Protection code that detects and responds to the hack.
- Advanced Countermeasure (when basic countermeasure code does not work
BD+ includes the ability to load native code (code that runs directly on the player's host process). It is allowed to deploy it only after it is proven that basic countermeasure code cannot address the hack.
