Abstract: A method of authenticating a user by means of a fingerprint authentication system comprising a finger sensing arrangement, comprising the following steps for each authentication attempt in a sequence of authentication attempts: receiving a touch by a candidate finger probe on the finger sensing arrangement; acquiring a candidate fingerprint image of the candidate finger probe; determining an authentication representation based on the candidate fingerprint image; retrieving a stored enrollment representation of an enrolled fingerprint of the user; determining a match score based on a comparison between the authentication representation and the enrolment representation; determining a liveness score for the authentication attempt; determining a qualification metric for the authentication attempt based on a relation between the liveness score for the authentication attempt and a liveness score for at least one previous authentication attempt; and determining an authentication result for the authentication attempt based on the match score, and the qualification metric.

Abstract: The present disclosure relates to a method performed in a fingerprint analysis system for facilitating differentiating between a live finger and a spoof finger. The method comprises acquiring a plurality of time-sequences of images, each of the time-sequences showing a respective finger as it engages a detection surface of a fingerprint sensor. Each of the time-sequences comprises at least a first image and a last image showing a fingerprint topography of the finger, wherein the respective fingers of some of the time-sequences are known to be live fingers and the respective fingers of some other of the time-sequences are known to be spoof fingers. The method also comprises training a machine learning algorithm on the plurality of time-sequences to produce a model of the machine learning algorithm for differentiating between a live finger and a spoof finger.

Abstract: A fingerprint sensing module comprising a fingerprint sensor device having a sensing array arranged on a first side of the device, the sensing array comprising an array of fingerprint sensing elements. The fingerprint sensor device comprises connection pads for connecting to external circuitry. The fingerprint sensing module further comprises a fingerprint sensor device cover structure, arranged to cover the fingerprint sensor device, having a first side configured to be touched by a finger, thereby forming a sensing surface of the sensing module, and a second side facing the sensing array, wherein the cover structure comprises conductive traces for electrically connecting the fingerprint sensor module to external circuitry, and wherein a surface area of the cover structure is larger than a surface area of the sensor device. The fingerprint sensor device comprises wire-bonds electrically connecting the connection pads of the fingerprint sensing device to the conductive traces of the cover structure.
