Microsoft and Fraunhofer attempt to use DRM against Open Source operating systems: Whitepaper: Interoperability Digital Rights Management and the Web http://www.fokus.fraunhofer.de/en/fokus/_pdfs/Interoperability_Digital_Rights_Management_and_the_Web.pdf >From that "whitepaper": "CDM interoperability can take three forms – browsers can use a Common CDM, or they can implement separate CDM modules tied to a Common DRM, or they can use separate CDM modules and separate DRMs and rely upon Common Encryption for interoperability. "All three approaches can work, but there are problems: "- Security: Enhanced content protection requirements make it highly likely that future DRMs will be more closely tied to hardware, with the actual CDM functionality happening outside the browser. "- State interoperability: if the CDM associated with a particular DRM is written by different parties, the state transitions of the CDM are likely to be inconsistent, effecting interoperability. "- Licensing: Many embedded devices will depend on the use of open source browsers. The open source browser community needs the ability to implement EME functionality without having to license CDM technology. "So CENC and EME only take us two-thirds of the way to solving DRM interoperability. The *complete solution* requires a means of enabling commercial media content to be played by open source browsers – to enable the *DRM to be a platform component* – ensuring security and state interoperability." "All three of the remaining issues with a Web interoperable DRM solution are addressed *if the DRM is baked into the platform*. The question is how best to accomplish this. The solution Microsoft has adopted is shown in Figure 4. ..." (emphasis added) In other words: abolishing Open Source operating systems is the aim and the attackers are asking the "Open Source browser community" to help them. Cheers, Andreas
