Biometric identification systems have come a long way from fingerprints and retinal scans to passwords based on sound resonance in the ear canal and so-called “brain prints”.
One of the newest developments at Baptist University (Hong Kong) is an identification system based on characteristic lip movements. The technology was patented in 2015. It tracks the unique features of lip movements when pronouncing a password, their texture and characteristic facial expressions. As shown by the test results, it is almost impossible to forge such a biometric fingerprint.
The "lip" password system can be combined with existing identification methods, for example, with face recognition to improve the efficiency of security systems. For a start, the researchers plan to "test" the new technology at ATMs and access control in public buildings.
