Abstract
The present invention relates to a method of controlling a fingerprint sensing system for liveness authentication. The method comprising acquiring a first set of sensing signals and a second set of sensing signals from a fingerprint sensor in two different operational modes and subsequently provide 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.
