Engineering students revolutionize forensic medicine by discovering that a person’s fingerprint can be identical
Engineers of Columbia and American Universities at Buffalo A new analysis has been made Fingerprinting by Artificial Intelligence (AI) K throw down It has long been recognized in forensic medicine that no two fingerprints are ever alike. Not even on different fingers of the same person.
The findings, which were published this Wednesday Science Advances MagazineIt has also been shown 99.99% confidence that fingerprints from any two fingers of the same person are much more similar than previously thought.
Fingerprints are required in Crime labs to solve cases, and to billions of mobile phones around the world for digital authentication.
Now, led by the study Gabe GuoAn engineering student at Columbia, along with other researchers from the same university and at Buffalo, have shown that it is possible to overcome this limitation through analysis. Various features Traces that were not considered until now.
Students a US government public database with about 60,000 fingerprintsSome from the same person and some from other people.
engineers, They extracted representation vectors from the footprints And they observed some Surprising results: Fingerprints of different fingers of the same person are very similar.
They discovered that the key was in peaks (the most prominent area of the footprint), since Orientation near the center of the footprints This explained many similarities and the pattern was repeated All pairs of fingers of the same person.
