Facial Blood Vessel-Scanning: Future Biometric ID

Facial Blood Vessel-Scanning Could Be Future's Biometric ID

We know about the importance of someone's unique identification. Biometric techniques provides us the way to access our personal information using unique identification. In the race of Biometric techniques, Facial blood vessel-scanning could be the next form of biometric ID.

A team of researchers at India’s Jadavpur University  in Kolkata came up with a identification system that can identify a person based not on the composition of their face, but on the blood vessels within it which is as unique as a fingerprint, iris or other characteristic. By scanning a person's face using an infrared thermal imaging camera, a computer algorithm can analyze the pattern of blood vessels beneath that face "almost down to the smallest capillary".

The accuracy of the system is said to be over 97 percent. Combined with an additional form of ID, such as a PIN, the system could satisfy even the most stringent security requirements.

It would be almost impossible to create a realistic mask for an impostor to wear that simulated the pattern of blood vessels in someone's face because no matter how good the mask, the thermal imaging camera would be able to see the impostor's blood vessels in their skin too and they would be unmasked, figuratively speaking.

Given the complexity that would be involved in first imaging the layout of the blood vessels within a person’s face, and then constructing a mask that convincingly replicated that layout, the scientists believe that their system would be very difficult to foil.
