Thermal Imaging Technology Makes Face Recognition Possible

    Date:2015-03-19 13:41:35
Have you ever heard that everyone in the world have different patterns of blood vessels? it is the prerequisite that makes the face recognition though thermal imaging technology possible.

Forget fingerprints or iris recognition, the next big thing in biometrics will be a thermal imaging scan that maps the blood vessels under the skin of your face for instantaneous face recognition that would be almost impossible to spoof.

                                                 

 

Writing in a forthcoming issue of the International Journal of Computational Intelligence Studies, a team at Jadavpur University in Kolkata, India, explains how the pattern of blood vessels just beneath the skin of our faces is as unique as a fingerprint, iris or other characteristic.

 

However, it would be almost impossible to create a realistic mask for an impostor to wear that simulated the pattern of blood vessels in someones face because no matter how good the mask, the thermal imaging camera would be able to see the impostors blood vessels in their skin too and they would be unmasked, figuratively speaking.
Ayan Seal and colleagues have developed a computer algorithm that can analyze the minutiae of the blood vessels revealed by an infra-red scan of a persons face. The thermogram readily reveals the pattern of blood vessels almost down to the smallest capillary with an accuracy of more than 97%. Such a degree of precision would suffice even for high-security applications provided the thermogram scan was tied to second or third forms of identity, such as photo ID, security card, PIN number etc.
At present,, the face recognition though thermal imaging technology is widely accepted by security systems, law enforcement and legal agencies, thermal imaging takes this fundamental human trait to a lower, subcutaneous, level.
