AI reveals shared fingerprint signature

A team from Columbia University has discovered that all fingers share a common biometric signature, invisible to the human eye but detectable by artificial intelligence. This finding challenges the traditional belief that fingerprints are unique to each finger.

Implications for criminal investigations

The discovery could significantly reform criminal investigations by providing a new method for identifying individuals from partial or degraded fingerprints. It also raises questions about a scientific dogma that has been in place for over a century.

Biometric security implications

This advancement may also influence the biometric security of devices, which currently rely on fingerprint recognition. The study suggests that AI could detect shared patterns, potentially improving or complicating current security protocols.

Reconstructed crime scene demonstration

On a reconstructed crime scene for the demonstration, a detective outlines the meticulous operations required to understand what happened and collect all evidence. This highlights the traditional methods used in forensic science to piece together events.

Evidence collection methods

DNA will be searched for on a cigarette and a cup, and a powder will visualize the "fingerprint traces," which may allow obtaining fingerprints. These methods are standard in forensic investigations and may soon be complemented by AI-driven analysis.
