Abstract: The present invention generally relates to a method for authenticating a finger of a user of an electronic device comprising a fingerprint sensor for sensing a fingerprint pattern, the method comprising the steps of: acquiring a candidate fingerprint image; determining, based on the candidate fingerprint image, a humidity level indication indicative of the humidity level of the finger; performing an authentication pre-process based on the humidity level indication; performing a fingerprint authentication process based on the pre-process to authenticate the user.

Abstract: The invention relates to a method of a fingerprint sensing system of enabling cancelling out impairment data present in an image captured by a fingerprint sensor of the fingerprint sensing system, a method of a fingerprint sensing system of cancelling out impairment data present in an image captured by a fingerprint sensor of the fingerprint sensing system, and a fingerprint sensing system performing the methods.

Abstract: A method for granting access for a user to a domain which is subject to an access restriction, wherein the user belongs to a group of one or more user shaving an access privilege in relation to the domain. The method comprises acquiring a first set of biometric data associated with the user. A first identification is successful if a comparison of the first set of biometric data to previously acquired data relating to the user, or to the group of users, indicates that the user belongs to the group. The method also comprises acquiring a second set of biometric data associated with the user responsive to the first identification being successful. A second identification is successful if a comparison of the second set of biometric data to previously acquired data relating to the user indicates that the user has the access privilege.

Abstract: The invention relates to a method of a fingerprint sensing system of enabling suppressing impairment data present in an image captured by a fingerprint sensor of the fingerprint sensing system, and a fingerprint sensing system performing the method.

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 method comprises capturing a plurality of images of a single biometric object during a single activation of a biometric sensor and ranking the images based on a ranking metric value of each of the images to determine a highest ranked image and at least one non-highest ranked image. The method comprises comparing, in a first matching attempt for the biometric object, the highest ranked image to templates of a plurality of pre-stored biometric object templates, wherein a matching metric is determined for each compared template, and generating a match indicating signal when it is determined that at least one of the matching metrics exceeds a matching threshold value. When it is determined that none of the matching metrics exceed the matching threshold value, one of the non-highest ranked images is compared, in a further matching attempt, to templates of the plurality of templates based on the matching metrics.

Abstract: The present invention generally 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, the electronic device further comprising a pre-processing module and a fingerprint sensor configured to acquire image data. The invention also relates to a corresponding electronic device and to a computer program product.

Abstract: The invention relates to methods and devices for enabling authentication of a user based on biometric data. In an aspect of the invention, a method performed by a client device of enabling authentication of user of the client device with a network node over a secure communication channel based on biometric data is provided.

Abstract: The present invention relates to providing a filtered fingerprint pattern signal indicative of a fingerprint pattern with a fingerprint sensing device comprising an array of sensing elements for sensing the fingerprint pattern. Each sensing element is configured to provide a sensing signal indicative of a local fingerprint pattern feature. The method comprises: receiving analog sensing signals from each of a set of sensing elements comprising at least four sensing elements, filtering the set of sensing signals to provide a set of filtered output signals each comprising a linear combination of the set of sensing signals in which each sensing signal has a respective coefficient. The coefficients in each linear combination sum up to zero, and wherein the linear combinations are different from each other. The set of filtered output signals are converted to a filtered digital sensing signal indicative of the user's fingerprint pattern.

Abstract: 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.

Abstract: There is provided a biometric imaging system comprising: a display panel comprising: a plurality of display pixels controllable to form an image in the display and a plurality of individually controllable non-visible light emitting elements configured to the emit non-visible light, the non-visible light emitting elements being configured to form a controllable spatial irradiation pattern within an irradiation zone defined by the plurality of non-visible light emitting elements; and a control unit. The control unit is configured to identify a biometric object facing the display panel; determine a relative location of the biometric object in the irradiation zone; control the plurality of non-visible light emitting elements to form a spatial radiation pattern based on the location of the biometric object in relation to the display panel.
