We have fingerprint and iris scans, now researchers are considering lip reading as a method of authentication.
Naked Security explains:
Fingerprint. Voice. Face. Today’s smartphones already include a wide variety of biometrics features that allow you to unlock your phone, access apps and even authorize payments. Now, researchers at Hong Kong Baptist University have come up with a new identity authentication system – using lip reading.
You’re probably asking yourself why we need yet another biometric technology. After all, biometrics have been touted as the replacement for passwords for years now with their promise of exceptional security and outstanding usability. But passwords are still here.
Biometrics have had challenges and these have significantly slowed progress, with cost and accuracy being the main two. But costs have reduced dramatically over recent years since biometrics shifted from being hardware-based and dependent on expensive specialist technology to software- and cloud-based and reliant solely on standard smartphone features such as cameras.
