The use of biometric data such as fingerprints to unlock mobile devices and verify identity at immigration and customs counters are used around the world. Despite its wide application, one cannot change the scan of their fingerprint. Once the scan is stolen or hacked, the owner can’t change his/her fingerprints and has to look for another identity security system. In view of this, Professor Cheung Yiu-ming of the Department of Computer Science has invented a new technology entitled “lip motion password” (lip password) which utilises a person’s lip motions to create a password. This system verifies a person’s identity by simultaneously matching the password content with the underlying behavioural characteristics of lip movement. Nobody can mimic a user’s lip movement when uttering the password which can be changed at any time. This novel technology, the first in the world and has been granted a US patent in 2015, is expected to be used in financial transaction authentication.
