A new ultrasonic fingerprint sensor measures 3-D image of your finger’s surface and the tissue beneath it — enhancing biometrics and information security for smartphones and other devices. Fingerprint sensor technology currently used in smartphones like the iPhone 6 produces a two-dimensional image of a finger’s surface, which can be spoofed fairly easily with a printed image of the fingerprint. A newly developed ultrasonic sensor eliminates that risk by imaging the ridges and valleys of the fingerprint’s surface, and the tissue beneath, in three dimensions.
