 Since November 2007, versions of BD+ protection have been circumvented by various versions of the AnyDVD HD program.Other programs known to be capable of circumventing BD+ protection are DumpHD (versions 0.6 and above, along with some supporting software), MakeMKV, and two applications from DVDFab (Passkey and HD Decrypter).ROM Mark is a small amount of cryptographic data that is stored separately from normal Blu-ray Disc data, aiming to prevent replication of the discs.
