Ever since the Trusted Computing Group went public about its plan to put a security chip inside every PC, its members have been denying accusations that the group is really a thinly-disguised conspiracy to embed DRM everywhere. IBM and Microsoft have instead stressed genuinely useful applications, like signing programs to be certain they don’t contain a rootkit. But at this week’s RSA show, Lenovo showed off a system that does use the chips for DRM after all. The system is particularly frightening because it looks so simple. There’s no 20-digit software key to type in, no dongle to attach to the printer port, no XP-style activation. (Is this what Bill Gates was thinking of when he said in his keynote that security needs to be easier to use?) The user interface is just a Thinkpad, albeit one of the new models with an integrated fingerprint sensor. When someone tries to open a DRM-restricted document (in this case, a PDF file: break that DRM and go to jail), Lenovo software asks the user to swipe a finger across the sensor. My finger results in an access denied message; the Lenovo security guy’s finger opens the document. If you’ve ever had a laptop stolen, this might sound useful. It is. In fact, encrypting hard disks or individual files is the main use that most vendors are promoting for the chip. Thinkpads have been able to do that since their IBM days, and now most other laptops can too. You can probably try it out by downloading software from your laptop manufacturer’s site, and Microsoft is building similar functionality into Vista as Palladium NGSCB Secure Startup BitLocker. The fingerprint sensor is also a good thing, if it’s just used for encryption. It’s even good for privacy: It means that network servers can authenticate you based on your fingerprint, without sending any fingerprint data over the network. (How? You authenticate to the chip in your laptop with your fingerprint, then the chip authenticates to the server with a digital certificate.) But DRM goes beyond encryption. In the system that Lenovo demonstrated, the decision about who can do what with the file is made by whoever generates the PDF, not by the person or organization that owns the laptop. According to Lenovo, the system is also aimed at tracking who reads a document and when, because the chip can report back every access attempt. If you access the file, your fingerprint is recorded. That might also sound useful, provided of course that you’re the one doing the recording and restricting. (I’d love to be Big Brother! Wouldn’t we all?) The problem is that you won’t be. Even if we forget about media companies for the moment, and assume that DRM is just for businesses that need to protect their sensitive documents from disclosure by employees or outsourcing partners, it’s still a bad tradeoff. A DRM system may seem to empower whoever is setting the restrictions (in this case, the PDF creator), but that’s just power by proxy. The real control lies with the hardware and software companies. They’re the ones who actually enforce the DRM and have the encryption keys, so they can hold your data to ransom. DRM customers are already locked into a single vendor: A DRM-restricted Word document can only be read by Word (not Org, WordPerfect or Writely), just as a DRM-restricted iTunes download can only be played on an iPod. Present versions of Word and iTunes still let customers escape by using the Windows clipboard or a CD burner, but that capability can be removed at any time. Relying on DRM means trusting all the vendors involved (in this case, Microsoft, Adobe, Lenovo and its component suppliers) more than you trust the users of the system. You need to trust the vendors both morally and practically: Can Microsoft be trusted not to abuse its power? And can Microsoft be trusted to develop a system that isn’t full of security holes? If you’re a movie studio or a record label, the users are your customers. You probably do trust Microsoft and the TCG more than your customers, so DRM might make sense. But if you’re an organization seeking to protect sensitive data, the users are your own employees and business partners. Are they really less trustworthy than Microsoft, its employees and its business partners? Source: Information Week
This type of thing is exactly why I'm so glad I converted to Linux. Yes Linux will utilize TCP, but only as a security mechanism as was originally and falsely promised by Microsoft. Not as a DRM platform, as is actually being implemented by Microsoft. Here's the EFF's take on TCP: http://www.eff.org/Infrastructure/trusted_computing/20031001_tc.php
George Orwell was right - everything we do and say will forever be recorded, processed and detained. Our lives will be on film, and the moment we slip up we'll disappear. The thought police are out to get us, so watch your back, and think about kittens.....
[ot]I'd rather take a stand and dissapear when nobody's looking than be a 'normal', unthreatening citizen who questions nothing and ascribes to groupthink mentalities. Of course, people of an activistic persuasion are in the overwhelming minority.[/ot]
Since reading about Trusted Computing a few years back, its obvious that Trusted Computing is DRM, an advanced evolution of it. Those three letters forever burn in hell.
