Abstract

The invention discloses a biometric system which may include an ultrasonic sensor array, a light source system and a control system. Some implementations may include an ultrasonic transmitter. The control system may be capable of controlling the light source system to emit light and of receiving signals from the ultrasonic sensor array corresponding to acoustic waves emitted from portions of a target object in response to being illuminated with the light emitted by the light source system. The control system may be capable of performing a user authentication process that is based, at least inpart, on the signals from the ultrasonic sensor array.

Description

[0001] priority claim [0002] This application claims priority to U.S. Application No. 15 / 149,046, filed May 6, 2016, and entitled "BIOMETRIC SYSTEM WITH PHOTOACOUSTIC IMAGING," which is hereby Incorporated by reference. technical field [0003] The present invention generally relates to biometric devices and methods, including but not limited to biometric devices and methods suitable for mobile devices. Background technique [0004] As mobile devices become more and more multifunctional, user authentication becomes increasingly important. Increasing amounts of personal information can be stored on and / or accessed by mobile devices. Furthermore, mobile devices are increasingly being used to make purchases and perform other business transactions. Some mobile devices, including but not limited to smart phones, currently include fingerprint sensors for user authentication. However, some fingerprint sensors are easily spoofed. Improved authentication methods will be requi...
