Title: FINGERPRINT SENSING SYSTEM WITH LIVENESS DETECTION
Abstract:
The present invention relates to a method of controlling a fingerprint sensing system(2)for liveness authentication. The method comprising acquiring a first set (S606, S802, S902) of sensing signals and a second set (S612, S804, S904) of sensing signals from a fingerprint sensor (3) in two different operational modes and subsequently provide (S614, S912) a liveness authentication signal based on the first set of sensing signals and the second set of sensing signals. The invention also relates to a fingerprint sensing system and an electronic device (1).
