For the first time, scientists have used artificial intelligence (AI) to connect two fingerprints left by different digits belonging to the same person. The new technique could potentially revive some cold cases — although some forensic experts have downplayed the discovery’s significance.
It's long been suspected the same person's fingerprints from different digits share important similarities, yet law enforcement has never been able to match these in practice. Current forensic techniques can only accurately link fingerprints from the same digit.
