| Sep 26, 2008 - Microsoft offers CD and DVD copy-protection - 02! |

With Microsoft's Windows Data Media Session Toolkit companies can create so-called "second session" copy protection. This means a CD or DVD contains a layer of data that allows playback on normal CD and DVD players and another layer designed specifically for playback on PCs.
The second layer will only work with Microsoft's Windows Media Player and is encrypted to limit copying or playback. For example, tracks could be played a limited number of times in the case of a promotional release.
Joshua Duhl, of the US analyst firm IDC, says the new software may encourage more companies to use copy-protection. Duhl told New Scientist: "I would expect in the next year you'll see more companies using DRM."
Duhl adds that Microsoft is developing a broad digital rights management strategy which apparently includes development of a new version of the Windows operating system, called Palladium. This operating system could be used to place restrictions on the use of files on personal computers.
Microsoft is not the only company hoping to make money from copy-protection. Real Networks announced software called Helix that can be used to protect multiple formats last week. "It's like a great land grab," Duhl says.
