Currently, smartphones come with a built-in biometric authentication system. Specifically from fingerprints. However, some are more efficient than others. In that sense, is it possible to violate this technology? In a stronger scenario, can you unlock a smartphone with an amputated finger?

Kieran Higgins, an older man from Spain, seems to have the answer. This person suffered an accident crane that affected his hand. Consequently, the doctors had to point the right index finger at him.

However, Higgins did not dispose of the amputated finger, instead keeping it in a bottle with alcohol. This as a form of prevention in case the insurance company refused “to pay your personal accident policy.”

Higgins tried to unlock his Galaxy A20 with the amputated finger, did he succeed?

Indeed he did, the Spaniard managed to unlock his smartphone with the amputated finger. At first glance, the fact appears as somewhat far-fetched. But if we analyze a little, it makes sense, then, the Samsung Galaxy A20 fully fulfilled its biometric function: to recognize a fingerprint pattern.

Regardless of whether the finger is warm, cold or lifeless, it has a unique identifier. After all, fingerprints are unrepeatable. In this regard, Samsung has not given any statements. But Lucas Francese, director of Biometric Devices at the French manufacturer Thales, had the following opinion:

“… In this case there is no technical problem. The finger registered in the system of that specific smartphone was the same that was used during authentication, so the system worked correctly. “

Higgins’s experiment makes it clear that there is no way to tell a living finger from a dead one. Regardless of the condition, both maintain a fixed pattern. Indeed, this action is not rebuttable or violates the privacy of the owner of the equipment. Worrying would be that the unlocking was done with a false fingerprint mold. Dont you think
