Revolutionary Fingerprint Scanner – Discerning Fake Fingerprints
One can beware of career crooks and villains now with BitFlow, the machine vision technology company that has created a revolutionary fingerprint scanner with the potential of discerning fake fingerprints from the real ones. While fingerprint scanners could be easy to fool, the new tech of BitFlow tends to scrap the process of photo scanning in favour of a method that looks inside the person’s finger.
Developed in amalgamation with the scientist at the Langevin Institute in Paris, France, the
new scanner can quickly and accurate capture what according to the team is a person’s internal fingerprint. Just as the fingerprints are seen on the surface of a finger, an internal fingerprint has the similar topographical features that resides around half a millimetre below the skin.
Besides this, the system also has the potential of imaging sweat pores in the finger of the person, thereby enhancing its means of recognizing an individual. The internal sensor, engineered by Langevin Institute postdoctoral researcher Egidijus Auksorius and scientific instrument professor, Claude Boccara, is based on a full field optical coherence tomography of FF-OCT.
FF-OCT Depends on 2D Detector
Different from the standard optical coherence tomography that makes use of the 3D data as well as lasers, the FF-OCT tends to depend on a 2D detector thus making it easy as well as faster for utilisation. Essentially the images of an internal fingerprint could be captured within a second on using this tech which is of great advantage for the fingerprint scanning industry.
The scanner analyses the difference interference patterns produced when in use, after a beam of light reflects off a sample, which is the finger, against a reference beam of light. For example when a light beamed at a finger tends to register with the system, it has the capabilities of seeing the different grooves, patterns as well as pores linked with someone’s unique fingerprint.
The reference beam of light that is a pure beam enables the scientist to precisely read the variations and chart the grooves and the patterns. As per the published press release of BitFlow, a study which was done by the Department of Homeland Security, it was observed the wearing of fake prints, or spoofing a fingerprint sensor beats a scanner by about 80 percent of the time.
Produces Fingerprint Biometric Data
Taking this into consideration, it is a surprising percentage in any given capacity. Auksorius and Boccara’s collaboration with BitFlow seems to be a forensics expert’s best colleague. The system is expected to produce fingerprint biometric data which is less vulnerable to spoofing and could also be popular if the concern for security of 2D scanners tends to rise.
However, with the other 3D imaging systems like the ones based on ultrasonic technology developing at the same time, size and the cost would be essentially important and the FF-OCT system could envisage stiff competition in that sphere. As per a scientific paper published in a leading journal, Auksorius and Boccara had initially used an expensive InGaAs camera though recently had demonstrated that images of the internal fingerprints of same quality could be recorded on utilising a new silicon camera from Adimec which is due to the camera’s high frame rate together with the pixel’s high capacity. A compact LED source releasing at 780 nm is utilised to provide the illumination.
