The electronic device further comprises housing connection circuitry connected to the electrically conducting housing, and arranged and configured to at least intermittently allow a potential of the electrically conducting housing to follow the finger excitation signal. Hereby the housing can be used to enhance the functionality of the fingerprint sensing system.

摘要： 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.

摘要： The present invention generally relates to a method for authenticating a user of an electronic device comprising a fingerprint sensor. The method comprises acquiring a sequence of verification images. Estimating, based on the images a first and a second verification force value indicative of a force applied by the object on the fingerprint sensor when the verification images were acquired. A verification image representation and a verification force value forms a verification template for each of the first and second images and forces. Matching the first and second verification template with at least one of a plurality of stored fingerprint enrolment templates in a respective first and second matching step. When the first and second matching steps each results in a positive match between the respective verification template and a respective one of the plurality of stored fingerprint enrolment templates, providing a signal indicating successful authentication of the user.
