The present disclosure relates to a method of authenticating a user by means of an electronic device comprising a user output interface. The present disclosure also relates to a corresponding electronic device and to a computer program product.

Authentication method for an electronic device

Method of multi-finger enrollment for a user

A method for providing user input on an electronic device comprising a fingerprint sensor comprising an array of sensing elements. Acquiring partial fingerprint images of a finger touching a finger touch surface of the fingerprint sensor from at least two sub-groups of sensing element. Determining a respective force value indicative of a force applied on the finger touch surface at each of the sub-groups of sensing elements when the partial fingerprints were acquired, based on the partial fingerprint images acquired from the respective sub-group of sensing elements. Determining a force value difference between a pair of the determined force values. Determining a user input based on the determined force value difference, and based on the relative location between the sub-groups of sensing elements in the pair associated with the force value difference.

Fingerprint sensing system and method for providing user input on an electronic device using a fingerprint sensor

The invention relates to a fingerprint sensing system and a method of the fingerprint sensing system of enabling authentication of a user based on fingerprint data captured by a fingerprint sensor of the fingerprint sensing system. The method comprises capturing at least one image of a fingerprint of a user's finger contacting the fingerprint sensor, acquiring a stored image comprising impairment data caused by impairments that the fingerprint sensor is subjected to, extracting fingerprint feature data from the captured at least one image, extracting impairment feature data from the acquired image, and comparing at least a subset of the extracted fingerprint feature data to at least a subset of the extracted impairment feature data of the acquired image, and if there is a match the user is not authenticated.

Method of a fingerprint sensing system of enabling authentication of a user based on fingerprint data

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.

Template matching of a biometric object

The invention relates to a method of a fingerprint sensing system of extracting fingerprint feature data from an image captured by a fingerprint sensor of the fingerprint sensing system, and a fingerprint sensing system performing the method.

Extracting fingerprint feature data from a fingerprint image

The present disclosure relates to an electronic device comprising at least a first and a second biometric sensor arrangement, wherein the second biometric sensor arrangement being different from the first biometric sensor arrangement. The present disclosure also relates to a method for enrolling a user of such an electronic device and to a corresponding computer program product.

Enrollment scheme for an electronic device

The present invention relates to a method of enrolling a fingerprint of a user's finger using a fingerprint sensor, specifically allowing for an adaptability in a number of times the use's finger needs to touch/contact the fingerprint sensor for enrollment completion. The invention also relates to a corresponding electronic device and to a computer program product.
