3-D ultrasonic fingerprint scanning could strengthen smartphone security

An ultrasonic fingerprint sensor measures a three-dimensional, volumetric image of the finger’s surface and the tissues beneath, making it difficult to spoof (Credit: Dave Horsley/University of California, Davis) Researchers at the University of California, Davis and Berkeley have managed to miniaturize medical ultrasound technology to create a fingerprint sensor that scans your finger in 3D. This low-power technology, which could improve on the robustness of current-generation capacitive scanners, could […]
