AI Unravels the Mystery of Fingerprints: Are We Truly Unique?

Due to its uniqueness and permanence, fingerprint analysis is regarded as a valuable tool in the field of forensics and security because no two fingerprint patterns are identical, not even identical twins. There are so many unique aspects of fingerprints that even your own fingerprints do not match with the fingerprints of others.

However, there is new research utilizing artificial intelligence (AI) that claims that forensic fingerprint identification will undergo a substantial change.

There has been a recent breakthrough in forensics with the invention of a new artificial intelligence system developed by Columbia University engineers, which dispels a long-held belief in forensics: that fingerprints from a person’s different fingers are not all the same.

In the field of forensics, it is widely accepted that fingerprints on different fingers of a given individual are all different from one another, and therefore, unmatchable. Columbia Engineering undergraduate student Gabe Guo led a team that challenged this widely held presumption and questioned this widely held belief. 

With no prior forensic experience, Guo found a public database containing about 60,000 fingerprints and fed the fingerprints in pairs into an artificial intelligence-powered system called a deep contrastive network based on artificial intelligence. It is possible that the pair of fingers belong to the same individual at
