Researchers from the Hong Kong Baptist University (HKBU) have invented a new, more secure method for authentication – “lip motion password”. This technology uses a person’s lip movement to create a password, making it a valuable addition to various security systems.
Professor Cheung Yiu-ming from the Department of Computer Science, HKBU, and his team of researchers invented the new technology that creates a password using a person’s lip motions and then verifies their identity by simultaneously matching the password content with the underlying behavioral characteristics of lip movement. Since nobody can mimic someone else’s lip movement when uttering a password, and since the password can be changed at any time, this makes the new technology superbly valuable and useful.
The team used a computational learning model to extract the visual features of lip shape, texture and of course movement to characterize lip sequence. To train the models, samples of lip sequence were collected and analyzed.
The potential applications of this now patented technology are vast, but one of the more obvious applications include financial transaction authentication, so anything from electronic payment using mobile devices and transactions at ATM machines to credit card user passwords. In addition, lip passwords can be used together with other biometrics to enhance the security level of various systems.
