Abstract
Aspects of this disclosure relate to a biometric sensing device that combines sensing with an actuator for two way communication between a finger on a surface and the device. The sensor can also function as an actuator. A finger can be authenticated based on an image of the finger generated by the sensor and also based on a response to energy delivered to the finger by the actuator. Two way communication can provide more robust authentication than fingerprint sensing alone.
Claims19
An interactive biometric authentication system comprising:
- a sensor configured to generate biometric image data associated with an object, the sensor being further configured as an actuator to deliver energy to the object to enable interactive authentication between the interactive biometric authentication system and the object based on a response of the object to the delivered energy, wherein the biometric image data is received by the sensor at a first time and wherein an indication of the response of the object to the delivered energy is received at a second time different from the first time;
- and
- a processor in communication with the sensor, the processor configured to authenticate the object based on the biometric image data and also based on the indication of the response of the object to the energy delivered to the object by the sensor configured as the actuator, wherein the response is indicative of whether the object is alive and wherein the processor is configured to process the biometric image data for authentication of the object separately from processing the indication of the response of the object to the delivered energy.
