Internal Sony documents revealed by Wikileaks show that the Blu-ray Disc Association (BDA) is working on a new version of the Blu-ray copy protection Advance Access Content System (AACS) that requires an internet connection on first playback . AACS uses cryptography to control and restrict the use of Blu-ray discs and is the main copy protection of the format.
