The engineers American universities in Columbia and Buffalo I have created a new analysis of Fingerprint through artificial intelligence (Amnesty International) which – which cast down The long-standing belief in forensics is that no two fingerprints are ever alike. Not even on different fingers of the same person.

The discovery was published on Wednesday in Journal of the Advancement of ScienceIt was proven with A 99.99% confidence that fingerprints from any two fingers of the same person are much more similar than previously thought.

Basics in solving crimes

Fingerprints are necessary Laboratories Criminology To solve the issues, and on billions of mobile phones around the world for digital authentication.

Now, the study he leads Gabe Guoan engineering student at Columbia University, in collaboration with other researchers from the same university and from Buffalo, showed that it is possible to overcome this limitation by analyzing Different properties Of the effects that have not been taken into account so far.

The students found A A public US government database containing about 60,000 fingerprintsSome are from the same person and others are from different people.

Engineers, They extracted representation vectors from footprints And they noticed each other Surprising results: Fingerprints from different fingers of the same person are very similar.

They discovered that the key was in Hills (the most prominent area of ​​the footprint) since then Direction near the center of the footprints He explained a lot of this similarity and that the pattern was repeated in it All pairs of fingers of the same person.
