New Identification Technology

The latest biometric technologies are growing, allowing for the ability to identify an individual not just by fingerprints, but also by voice, eye contact, standing ...

Today, a new algorithm by researchers at the University of Jadavpur in Kolkata, India, has been able to capture human blood vessels for identification via infrared technology.

Dr Seal's research, published in the International Journal of Computational Intelligence Studies, shows that scientists have used an infrared camera to capture the heat signature from the capillaries underlying the skin. Unlike arterial structures - which are almost identical in everyone, capillaries are tiny vessels, branched out of the arteries, and have a completely different structure on the individual.

'The heat images obtained from the blood vessels can be viewed as grooves on the fingerprints. As a result, fingerprint recognition technology can be applied to human faces, "said Dr. Seal.

This technology outperforms other identification technologies by using only thermal imaging. This means that the technology can work in completely no-light conditions, even when subjected to a mask. This approach can be applied in the security sector, for example in banks. It has even been suggested that this technology be used in the medical sector, which helps to create a facial vascular map that can regenerate lost skin.

However, infrared scanning technology also has many limitations. TS Seal's algorithm does not work with moving objects, meaning it requires the cooperation of individuals when scanning infrared. What is most worrying about is the possibility that this technology could be abused to infringe on individual freedom. Because, as with the iris, infrared objects will not know they are being identified.
