Suprema reports it has supplied its BioSign 4.0 under-display fingerprint recognition algorithm for Samsung Galaxy S21 smartphones with support from Qualcomm Technologies.

BioSign 4.0 is 50 per cent faster and more than twice as accurate in terms of recognition performance than the previous iteration. BioSign 4.0 employs deep-learning mechanisms to optimise fingerprint analysis to efficiently recognise rich fingerprint information obtained from the larger sensing area of the second-generation Qualcomm 3D Sonic Sensor Gen 2 installed in the Galaxy S21 series.

With a 77 per cent larger fingerprint sensing area, the Qualcomm 3D Sonic Sensor Gen 2, can significantly improve fingerprint recognition performance. The ultrasonic sensor has ultra-thin form factors and is optically isolated from the display panel, allowing for sleek smartphone designs.

“Suprema’s fingerprint recognition technology has been continuously selected for the Samsung Galaxy S series, proving to the world the technological superiority of our solution,” said Brian Song, president of Suprema.
