Remove Copy Protection from Blu-ray Movies

The commercial Blu-ray discs are typically protected with some form of heave copy protection. Apart from the commonly used BD+, AACS, there are also many other copy protection such as region codes, Cinavia, UOP, Digital rights management, High-bandwidth Digital Content Protection and BD-ROM Mark adopted by Blu-ray discs to prevent unauthorized access to Blu ray disc. Although it is illegal to copy protected Blu-ray disc for commercial use, however, many Blu-ray disc owners believe that they own the rights to copy the Blu-ray disc for personal use since they have paid for it. The following article will introduce several distinct level of copy protection and how to legally and effectively bypass all Blu-ray copy protection with reliable Blu-ray copy protection removal.

Different distinct levels of Blu-ray copy protection

AACS encryption

The first level of copy protection applied to pre-recorded discs is the Advanced Access Content System (AACS) developed by the AACS Licensing Administrator, a consortium of companies including Disney, Intel, Microsoft, Panasonic, Warner Bros., IBM, Toshiba and Sony. It is based on Advanced Encryption Standard (AES), a robust 128-bit key encryption system developed by the US government.
AACS includes a system by which the keys assigned to a particular player can be “revoked” for future Blu-ray disc releases if it is determined that those keys have been compromised. When a newer Blu-ray disc is inserted into an older drive, the drive is required to check the version of the “Media Key Block” (MKB) on the disc and, if it is newer than the one the drive has internally, to copy over to permanent non-volatile memory the newer MKB. Thus playing newer discs propagates the revoked key lists out to all drives.
AACS was broken beginning in late 2006, and numerous AACS decryption programs are available online. The key revocation system ensures, however, that the AACS licensing organization and the hacker community are constantly playing a cat-and-mouse game.

BD+ protection

BD+ is a second level of copy protection that is optional for pre-recorded Blu-ray discs. After the stream files are encrypted using AACS encryption, they are further mangled randomly with instructions on how to repair the mangled files stored on the disc as special BD+ instructions. These instructions run in something called a “BD+ virtual machine”, special software that Blu-ray players are required to include. The virtual machine on the player runs the BD+ code on the disc and retrieves something called the “Fix-up Table” (FUT) to repair all the BD+ mangled regions on the disc.
BD+ was broken in 2008 by reverse-engineering the BD+ virtual machine. Each new BD+ Blu-ray disc release brings new twists in the virtual machine programs, each of which are again reverse-engineered by the hacker community. Just as with AACS, BD+ has become a cat-and-mouse game.
Currently, the BD+ system is owned by Irdeto, which bought it from Rovi Corporation in 2011.

Cinavia Protection

Cinavia, developed by a company called Verance, is a newer level of copy protection that is optional on Blu-ray discs. The system involves “steganography” or watermarking, in which a special encrypted data signal is hidden within a single audio channel in an audio track. Verance claims the Cinavia signal is inaudible, and that the signal can survive audio compression and recompression.

When a player with Cinavia support detects a Cinavia signal on a Blu-ray disc, it can verify whether playback should be allowed. The player can display one of four possible messages known as “Cinavia message codes”. The most commonly viewed messages are (1) “Playback Stopped” and (3) “Audio Muted”. Message (1) is supposed to stop distribution of “camcorder” recordings of first-run movies from theaters if the theaters include a Cinavia signal in the movie soundtrack. Message (3) is supposed to stop unencrypted ripped copies of movies. There is apparently no exception for consumer backup copies.

Cinavia detection became a requirement for Blu-ray players beginning in 2012. To date, the only major studio that appears to be using Cinavia is Sony Pictures, and that is not even for all releases. Most of the major studios seem to be hesitant about including Cinavia protection, perhaps because the system involves expensive royalty fees, or perhaps for fear of angering customers.

Customers have a reason to be angry, because unlike all the other protection schemes on Blu-ray and DVD discs, Cinavia protection is destructive and permanent. Audio tracks that include Cinavia have been deliberately damaged, and the damaged audio is present both for legimitate customers and for the supposed content pirates. When the audio track is protected with Cinavia, legitimate customers do not get the pristine audio content they paid for on their Blu-ray discs.

The Cinavia encoding system was broken in 2013, but it has proven very difficult to remove the protection and restore the protected audio track back to its original state. One ripper tool company claims to be able to do this, but their success rate is apparently spotty. Other ripper tool companies have figured out schemes to disable or fool Cinavia detection in players. Some stand-alone players (e.g. Panasonic, Oppo) have firmware patches available to remove Cinavia detection.
