Engineering Students Make Groundbreaking Discovery in Forensic Medicine: Same Person Can Have Identical Fingerprints

Engineering students revolutionize forensic medicine by discovering that a person can have the same fingerprints

Engineers from the American universities of Columbia and Buffalo have made a groundbreaking discovery that challenges the long-held belief in forensic medicine that no two fingerprints are ever alike, not even on different fingers of the same person. Using artificial intelligence (AI), the engineers have developed a new analysis of fingerprints that shows a 99.99% confidence that fingerprints from any two fingers of the same person are much more similar than previously thought.

The study, published in the Science Advances magazine, has significant implications for forensic science and digital authentication on mobile phones. Fingerprints are essential in forensic laboratories and criminology to solve cases, as well as for digital authentication on billions of mobile phones around the world.

Led by engineering student Gabe Guo, the team of researchers found a US government public database with about 60,000 fingerprints, some from the same person and others from different people. By extracting representation vectors from the fingerprints, the engineers observed surprising results: fingerprints from different fingers of the same person are extremely similar.

The key to this similarity was found in the ridges, the most prominent area of the fingerprint, and the orientation near the center of the fingerprints explained much of this similarity. This pattern was found to be consistent in all pairs of fingers of the same person.

This discovery has the potential to revolutionize forensic medicine and fingerprint analysis, as well as the field of digital authentication. It challenges widely accepted beliefs and could pave the way for new methods of identifying individuals based on their fingerprints.
