Abstract: In a fingerprint sensing system, a determination is made of a center of attention, COA, point. The COA point is a point on a finger of a user that is likely to be in proximity of the center of a fingerprint image of the finger obtained by a fingerprint sensor. This COA determination is used in guiding the user in a fingerprint enrolment procedure.

Abstract: 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 the at least one touch sensor signal.

Abstract: The present invention relates to a method for controlling a device controller of an electronic device comprising a fingerprint sensor to transition from an at least partly active mode to an at least partly in-active mode. The fingerprint sensor itself is used for determining a presence of a finger on the fingerprint sensor, wherein a device controller is maintained in an at least partly active mode if a finger is detected on the fingerprint sensor. The present invention also relates to an electronic device comprising a fingerprint sensor and a device controller.

Abstract: The present invention relates to a method for transitioning a device controller comprised with an electronic device from an at least partly inactive mode to an at least partly active mode, wherein the method comprises: determining the area portion of a finger detecting structure being touched by an object; determining a force applied on the fingerprint sensing device. When the area portion of the finger detecting structure being touched by the object exceeds a predetermined threshold area portion, and the force exceeds a predetermined threshold force value, transitioning, using the pre-processing module, the device controller from the at least partly inactive mode to the at least partly active mode. The invention also relates to such an electronic device.
