South Korean biometrics firm Suprema has revealed that Samsung will use its mobile fingerprint authentication algorithm in flagship smartphones.Suprema's BioSign mobile fingerprint authentication algorithm has been selected by Samsung for the Galaxy J5 2017 and Galaxy A7 (for SK Telecom) smartphone models. It is partnering with Egis Technology, a Taiwan-based sensor provider, on the projectSuprema introduced BioSign 2.0 in February at the Mobile World Congress in Barcelona.BioSign 2.0 supports small fingerprint sensors and the firm says it offers robust authentication performance over time and environment. Suprema has said that BioSign 2.0 is an “essential” solution for mid-to-low range smartphones as it “reduces production cost by supporting smaller sensors”.The makers say that BioSign 2.0 achieves 50ms authentication speeds in high-end smartphones with high performance processors and 100ms speeds with low-end processors while guaranteeing a maximum of 0.0005% FAR.”Like a camera, fingerprints are now an essential feature in smartphones, initially in premium phones and now in mid-to-low range phones. BioSign 2.0 is the most economical and efficient solution in mid-to-low range smartphones. Starting with the Samsung Galaxy J5 2017 and Galaxy A7, we expect to see BioSign 2.0 becoming widely available in many other smartphone models.
