Lip Password: Double Security System for Identity Authentication

The use of biometric data such as fingerprints for identity verification is used around the world. If the scan is stolen or hacked and since the owner cannot change his/her fingerprints, people have to look for another identity security system. We have invented a new technology entitled “lip motion password” which utilises a person’s lip motions to create a password.

• “Lip motion password” is a patented double security system to verify a person’s identity by simultaneously matching the password content with the underlying behavioural characteristics of lip motions.
• The system enables users to complete authentication by uttering a short phrase of their choice of password. Nobody can mimic a user’s lip movement when uttering the password.
• It is not necessary for the speaker to read aloud their password as the lip sequence is analysed visually by the system. Hence, the system would allow people with speech disabilities to use it.

• The dynamic characteristics of lip motions are resistant to mimicry, so a lip password can be used singly for speaker verification, as it is able to detect and reject a wrong password uttered by the user or the correct password spoken by an imposter.
• Compared with traditional voice-based authentication, the acquisition and analysis of lip movements are less susceptible to background noise and distance, moreover, it can even be used by a speech-impaired person.

• It can be used in financial transaction authentication or used together with other biometrics to enhance the security level of systems.
