At a conference held by the DVD Forum in Berlin, the Advanced Access Content System Licensing Authority (AACS LA) unveiled its plans to fight back specifically against SlySoft's AnyDVD HD application, which can rip content from HD DVD and Blu-ray movie discs. The group also appears to be interested in fighting CAM piracy (movies recorded by camcorders in theaters) with video watermarking technology.
Back to its main purpose, to protect HD DVD and Blu-ray movie discs from being copied, "data keys" will provide additional encryption during the transmission of data from the drive to the PC (bus encryption). The keys will be different for each drive and each movie discs. According to AACS LA, even if hackers found and posted keys, it would not enable anybody else to decrypt the discs with their equipment.
The keys currently being used by SlySoft's AnyDVD HD will soon be revoked also, meaning that the software will be incapable of decrypting newer titles and that users with HD playback software will probably soon need to update.
