Quick hit: Infrared imaging used for biometric identification

A thermal imaging camera was used to identify the blood vessels below the surface of the face, which produces a unique pattern for biometric identification.

A new method of biometric identification where thermal imaging is used to identify the blood vessels below the surface of the face has been developed by a team at Jadavpur University in Kolkata, India.

The method will be covered in an upcoming issue of theInternational Journal of Computational Intelligence Studies, where it suggests that patterns of blood vessels beneath the surface of the skin on the face are as unique as a fingerprint. Using an infrared camera, these patterns can be revealed and used as unique identifiers, which would be nearly impossible to replicate, as potential identity thieves would not be able to escape the camera’s identification of their blood vessels.

An algorithm developed by researcher Ayan Seal and his colleagues at Jadaypur University analyzes the blood vessels almost down to the smallest capillary with an accuracy of more than 97%, according to ScienceDaily.
