It seems to me the main flaw lies in the system being 2D instead of 3D. It will be much harder to beat if it is 3D. Or even 4D (with gestures or so). Also, it should perhaps combine voice and fingerprint with it. To ultimately recognize a voice it would require a better microphone and audio application that are normally available in laptops. It will cost a small fortune to secure your laptop.

I'm not sure I want to pay a small fortune to protect my bitorrent files of Bleach.

What makes you think this would have to be a small fortune?

All they need to do to make this work is put 2 webcams, one on each side of the laptop with a slight angle inward. They could then recognize images in 3d space as well as detect the use of photographs or flat planes for images.

That would invalidate the photo/generation attacks, and add less than $20 in parts. The software would be more complex but it would likely be significantly more secure.

At that point someone could beat the system with a 3d printer, or master sculpting skills - but it would be more secure than a thumb print which can be faked with a high resolution picture of a finger print that you literally lick first (to fool sweat detection) It would likely become a more than reasonable level of security for classified information. Integrating that would be more secure than complex passwords people forget or write on sticky notes.

This technology is not flawed.

It's version 1.0 that's all...

I think the quality of the webcams being used also has a huge impact. These integrated webcams have a resolution no larger than 640x480 and this surely must make a big difference in terms of finding distinguishing characteristics.

I do like your idea of mixing with fingerprint or voice, although I think voice would be a bad idea, as getting a cold could render your workday useless ;)

I like your 3d idea too, perhaps having 3 cameras with one mounted in the center and two mounting on the sides but on an angle. This matched with voice recognition would make it a lot harder to breach.
