Blu-Ray Copy Protection Breached

A West Indies company says it has defeated the BD+ DVD copy protection scheme, which was thought to be virtually impenetrable.

The second line of defense to prevent Blu-ray discs from being copied has been breached: SlySoft, a software company based in Antigua, West Indies, said last week that its AnyDVD HD 6.4.0.0 disc copying program can now "make backup security copies of Blu-ray discs protected with BD+."

The first line of defense for Blu-ray discs, the Advance Access Content System (AACS) copy protection scheme, was defeated in late 2006. Efforts to keep the 32-bit AACS processing key off the Internet failed spectacularly in 2007 when foes of copy protection schemes posted the sensitive number in a variety of forms on Digg and other Web sites.

The technology behind BD+ was developed by Cryptography Research and sold to Macrovision in November 2007. BD+ is supposed to serve as a secondary layer of protection to prevent Blu-ray disc content from being copied.

In the July 8, 2007 issue of Home Media Magazine, Richard Doherty, a media analyst for the Envisioneering Group, said BD+, unlike AACS, wouldn't likely be breached for 10 years.
