Suprema goes mobile

Suprema recently showcased BioSign 3.0, an AI-based in-display fingerprint authentication algorithm, together with LookSign, a 3D facial recognition solution at Mobile World Congress 2018, held in Barcelona.

Featured in Samsung Galaxy J5 2017 smartphones, Suprema BioSign is now enhanced, leveraging Suprema’s proprietary AI technology. Coupled with LookSign, the company’s latest 3D facial recognition solution, Suprema plans to penetrate the next generation premium smartphone market.

In the case of in-display fingerprint recognition, algorithm complexity is known to be very high due to its sensor structure and imaging characteristics. Consequently, the algorithm now plays a more critical role in recognition performance compared to conventional sensors.

The in-display oriented BioSign 3.0 provides a higher level of ­recognition performance and speed by combining Suprema’s two decades of expertise in optical fingerprint imaging and AI technologies. The company has teamed up with major sensor producers around the world for next-generation premium smartphones.

At the show, Suprema also revealed LookSign, a 3D facial recognition technology for smartphones. Last year, the company launched FaceStation 2, a facial recognition access control terminal, featuring Suprema’s own near-infrared imaging technology. Award winner of Sweden’s Detektor International Award 2017 in Best Access Control Products, FaceStation 2 outperforms most of today’s facial recognition devices and features the world’s fastest matching speed of 3 000 match/sec, highest operating illuminance up to 25 000 lx, and lowest error rate of FAR at 0,00002%.

LookSign blends FaceStation 2’s facial recognition technology with 3D image processing techniques to produce an optimised algorithm for smartphones. LookSign uses surface light source and patterned light to gain 2D and 3D information to provide more accurate recognition performance and a higher security level. Suprema has plans in place to discuss co-operation with sensor producers to develop integrated solutions.

“Suprema’s core competitiveness is ongoing technological innovation. BioSign 3.0 and LookSign will showcase a new leap in biometric technology in the smartphone market and attract more smartphone manufacturers,” said Brian Song, CEO at Suprema. “As a fingerprint recognition algorithm technology, BioSign provides superior authentication performance and matching speed, even in a small sized fingerprint sensor of 4 x 3,2 mm, and it is an essential solution for applying fingerprint recognition functionality to mid-to-low range smartphones, as well as high-end smartphones.”
