British biometric technology firm AimBrain has unveiled a new authentication technology that, it claims, uses lip synchronisation to help improve security and fight fraud.
The company, which has developed a range of identity and security solutions, has added optional audio and lip-syncing features to its facial authentication module.
Called AimBrain LipSync, the company said it designed the technology to "prove liveliness" and "counter even the most sophisticated spoofing technologies".
It claims that the solution provides customers with "stronger" user authentication capabilities because it combines facial recognition with spoken word and lip movement analysis.
Biometric systems play an important role in combating fraud in a range of industry verticals, including financial services. They determine whether photos, videos and computer-generated simulation are not posing as humans.
However, most of these technologies only use facial authentication and algorithms to process images at low levels.
AimBrain claims that combining existing solutions with lip synchronisation could be game-changing.
Efstathios Vafeias, lead scientist at AimBrain, said the company has attempted to "take a different approach to the problem".
Its technology uses both visual and audio data to detect whether someone is real or not.
"By asking a user to say a randomised number to the camera, our technology now not only authenticates their face against a template but verifies that the numbers match the prompt and analyses the synchronisation between the voice and lip movement," he explained.
"So, as well as providing a step-change in security, this method maintains accuracy while being less susceptible to hardware or environmental changes."
AimBrain believes its technique could eventually replace passwords and two-factor authentication. There are three components, including facial recognition, liveliness detection and anti-spoofing technology.
Andrius Sutas, CEO and co-founder at AimBrain, added: "Many of today's anti-spoofing technologies can be fooled using the simplest of measures.
"We have all seen the high-profile hacks that have beaten new smartphone biometric security systems within days of their release.
"Our lip sync technology means that to beat it, an attacker must be human, look exactly like the user and correctly say a random number, while we analyse the lip movements, within a limited timeframe. The level of sophistication required for an attack goes far beyond ordinary capabilities."
