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.

I feel like i'm stalled on the railroad track, about to be hit by
the "trusted computing" freight train, but you don't need to
worry. It will never be used against you. rcgreen is just
paranoid.
