What is AACS protection?
The AACS (Advanced Access Content System) is the first level of copy protection applied to pre-recorded discs 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.
Remove AACS copy protection
On 26 December 2006, a person using the alias “muslix64” published a working, open-sourced AACS decrypting utility named BackupHDDVD, looking at the publicly available AACS specifications. Given the correct keys, it can be used to decrypt AACS-encrypted content. A corresponding BackupBluRay program was soon developed. Blu-ray Copy is a program capable of copying Blu-rays to the hard drive or to blank BD-R discs.

Step by Step to Bypass Blu-ray AACS Copy Protection
Step 1: Load Blu-ray disc into the program.
Run the program on your computer, insert the Blu-ray disc into an external Blu-ray drive. Click “File” > “Load from disc” to load Blu-ray disc into the program. Apart from Blu-ray disc, you can also use the program to rip Blu-ray folder and ISO image file.
Tips: The program can automatically detect the main Blu-ray title (the one with largest file size and longest length) for you.
Step 2: Copy Blu-ray in different ways.
Full disc copy
Make a full disc copy by hitting the 
icon on the top tool bar of the main interface.
Main movie copy

Output digital file formats or device preset profile formats
From “Format” bar drop-down list, select one of your desired file formats or device preset profile formats according to your own needs.
Step 3: Start Blu-ray AACS protection bypassing process.
After finishing all the settings, go back to the main interface, press the right-bottom “Convert” button to start to rip AACS encrypted Blu-ray movies to your desired file formats.
When the conversion is completed, click “Open output folder”, a window will pop out with all your converted files. Then you will have no limitation to play the ripped Blu-ray movies on your smartphones, tablets, game consoles, TVs, etc.
