Fingerprint authentication uses ultrasound without storing biometric information as digital data

Fingerprint authentication uses ultrasound without storing biometric information as digital data

A research team has developed a new biometric authentication technology that can identify users without storing their fingerprint information as digital data. The study is published in Nature Sensors.

Ultrasound Metasurface Authenticates Fingerprints Without Ever Storing Them

POSTECH researchers have developed an ultrasonic metasurface system that authenticates fingerprints through physical wave computation, achieving up to 99.75 percent accuracy without storing any biometric data.

New fingerprint scanner recognizes you without storing your fingerprint

Researchers have developed an experimental fingerprint recognition system that makes its decision using sound waves instead of comparing stored digital fingerprint records. The approach could reduce the amount of sensitive personal information that needs to be kept inside a device. That matters because a fingerprint is harder to replace than a password. If a digital […]
