New Technology Combines Lip Motion and Passwords For User Authentication (bleepingcomputer.com)

An anonymous reader writes: "Scientists from the Hong Kong Baptist University (HKBU) have developed a new user authentication system that relies on reading lip motions while the user speaks a password out loud," reports BleepingComputer. Called "lip password" the system combines the best parts of classic password-based systems with the good parts of biometrics. The system relies on the uniqueness of someone's lips, such as shape, texture, and lip motions, but also allows someone to change the lip motion (password), in case the system ever gets compromised. Other biometric solutions, such as fingerprints, iris scans, and facial features, become eternally useless once compromised.

Iris scans and facial recognition are much the same. You may be able to fool the scanners of today, but not necessarily the scanners of tomorrow.
