FINGERPRINT AUTHENTICATION USING TOUCH SENSOR DATA

摘要

The present invention relates to a method of authenticating a candidate fingerprint by means of an electronic device comprising a touch sensor;and a fingerprint sensor. The method comprises the steps of: acquiring at least one touch sensor signal indicative of a sub-area of the touch sensor being touched by the candidate finger;acquiring at least one fingerprint image of the candidate fingerprint;retrieving a stored enrollment representation of the enrolled fingerprint of the enrolled finger;determining an authentication representation of the candidate fingerprint based on the fingerprint image; and determining an authentication result based on the authentication representation, the stored enrollment representation, and th eat least one touch sensor signal.
