LAYERED FILTERING FOR BIOMETRIC SENSORS
First Claim
1. A fingerprint sensing apparatus, comprising:
- a fingerprint sensor system; and
a control system capable of;
receiving fingerprint sensor data from the fingerprint sensor system;
determining, according to the fingerprint sensor data, whether an object is positioned proximate a portion of the fingerprint sensor system; and
, if the control system determines that an object is positioned proximate the portion of the fingerprint sensor system,determining whether the object is a finger or a non-finger object.

Abstract
A fingerprint sensing apparatus includes a fingerprint sensor system and a control system capable of receiving fingerprint sensor data from the fingerprint sensor system. The control system may determine, according to the fingerprint sensor data, whether an object is positioned proximate a portion of the fingerprint sensor system. If the control system determines that an object is positioned proximate the portion of the fingerprint sensor system, the control system may determine whether the object is a finger or a non-finger object. The control system may determine whether the fingerprint sensor data includes fingerprint image information of at least an image quality threshold.
