Vein Patterns to Verify Identity

JonN writes "Fujitsu Ltd. will start selling a biometric security device next month that relies on vein patterns in the hand to verify a user's identity, it said today. The palm-vein detector contains a camera that takes a picture of the palm of a user's hand. The image is then matched against a database as a means of verification. The camera works in the near-infrared range so veins present under the skin are visible, and a proprietary algorithm is used to help confirm identity. The system takes into account identifying features such as the number of veins, their position and the points at which they cross."

Well, to an infrared vein scanner that works entirely by imaging the heat given off by your circulating blood, a severed hand will be every bit as valid as one made of wood.

Not that I expect the bad guys to be smart enough to know this up front (so we might still be losing a few hands to some idiots) but the entire technology functions as a liveness detector.

3 answers.
1. The tubes for the computer were designed to be used this way. The hand is intended to pump blood and once it loses pressure it colapses and becomes fairly disfunctional.
2. A pump designed to handle pumping water into a hand is pritty complicated technology. At this point your better off using some sort of electronic bypass system like the devices used to trick slot machines into giving you a "win"
Maybe a heat patern "copy" using a heat emitter fake hand. Then you need only scan the original to have a key that works forever.

3. The results won't be the same. The water will leak heat more than blood will and heat up the surrounding tissue. The sensor will get a blur and probably give a negitive.
