Lip Passwords – The New Trend in Biometric Security

New suggestions are already made by computer science experts to bring up a whole new method we use to login to our devices – lip motion reading. This feature is believed to have some very interesting advantages over the biometric passwords.

One of the main benefits of using lip reading technology is that it can be changed, while if fingerprint or face recognition techniques are used, they cannot be. There are other weaknesses to those scanners, like the fact that face recognition software can easily be tricked by using a physical picture of the person in the device itself. And fingerprint scanners can also be modified to be hacked by copying your fingerprint on a fake silicone finger, for example. This makes biometric features not as reliable as once thought to be, if you are targeted, that is.

This is where a computer scientist Cheung Yiu-ming from the Hong Kong Baptist University suggests that there is another alternative solution to device security – lip motion scanning software. Such “lip passwords” can allow for the owner to simply speak the password, and even if he speaks it silently, the motions from the lips will be recorded from the camera. Then, specific algorithms will be trained and tested to check different parts of the lip move in different directions.

This type of training to recognize specific lip movements can also be sophisticated into recognizing a lip set only of one individual i.e. the one who is using the phone, making it difficult for people to unlock your phone even if they are speaking the same password for unlock.

Other benefits with which it can be combined were also reported by experts to be facial recognition mechanisms and even voice recognition technology.

This idea can be implemented in other places as well, varying from different IoT devices, to even point of sale systems as well as vehicle engine starting and unlocking. Very clever indeed and we are looking forward for this technology to develop.
