Clash between Linux and encryption 'inevitable'

Digital rights management (DRM) uses encryption to protect proprietary content such as music or movies. But it's not just for entertainment: DRM also will govern confidential documents and other mainstream business information, said Martin Fink, HP's vice president for Linux, speaking at a keynote address at the LinuxWorld Conference and Expo.

Right now there is a risk that DRM adoption will lock out Linux and open-source software, Fink said. "Unfortunately, DRM and open-source software are today largely incompatible because of an extension to copyright law called the Digital Millennium Copyright Act," Fink said.

Indeed, the tensions between open-source software and DRM have led to legal fights in the case of Linux support for the decryption needed to play movies on DVD. Ultimately, the solution to the DMCA problem will require lobbying to change the rules, Fink said; some in Congress have proposed changes to the law.

HP has a vested interest in the area: the company is angling to be both a major supplier of Linux gear and a key partner for those creating, disseminating and consuming digital content.

Fink didn't mention Microsoft by name, but the implication was clear that the software giant could prevail at the expense of open-source software because of DRM. "While there is a need to protect digital media in all its forms, it's also important that open software be able to participate in this environment. If we fail, we will create an environment in which one company has de facto control over your documents," Fink said.

Fink also had another criticism of the open-source realm: There are too many licenses. Some are widely used, such as the General Public License (GPL) that governs Linux itself, but there are dozens more.

At an Open Source Development Labs meeting last week, Fink learned there are 52 open-source licences, with three more expected soon.

"There is no value, and there is really confusion in having that many licences. If you're a vendor planning to create a new licence, stop. Call me. Tell me why," he said. "I approve three to five open-source projects or contributions a week" without having to employ any new licences, he added.

Despite the challenges, Linux and open-source software will prevail, Fink said.

Sales of Linux servers are expected to reach $9.7bn by 2008, and the operating system will spread into many other computing devices, he said. "Linux has the ability to be almost everywhere and in almost any mildly intelligent device you can think of," Fink said.

"Open source is going to allow companies to take cost out of the system at an amazing rate," Fink said. "Companies will not be able to afford to not take advantage of this change."

Also at the show, Fink touted HP's new Linux laptop, the nx5000, and demonstrated handwriting recognition on a tablet PC.
