Sony using blood vessel patterns for biometric authentication

Biometric security for our devices has been around for a while. I started seeing it really showing up about 3 years ago and since that time it has gone fairly mainstream.

Now Sony is trying to improve on the idea. By taking away the idea of scanning the fingerprint and instead scanning the unique arrangement of scattered light form the veins of the fingertip, Sony hopes to make the process faster and more reliable.

It uses a camera system called Mofiria which has a CMOS sensor to capture the image.

The neat thing about this is the speed with which the recognition can be done. Sony claims 0.015 seconds for a PC and .25 seconds for a mobile phone. That's a lot faster than the fingerprint scanner on my Tablet PC.
