New York-based biometrics firm Hoyos Labs has said it will demonstrate a new technology which captures four fingerprints on a smartphone simultaneously.The company's biometric four-finger (4F) technology will be shown at the Biometrics 2015 show in London, which runs from 13-15 October.”4F was invented to address the difficulty of capturing biometrics, like facial recognition, which can fail with adverse lighting conditions. 4F works in any environment, because it uses the phone's flash as its light source with no external hardware required”, said Hoyos.At the event, Hector Hoyos, CEO and Dr. Francis Mather, Director, Computer Vision Laboratory, Hoyos, will also be giving a talk on 4F, describing it as “touch-less four-finger acquisition with 150 degrees of freedom”.
