Abstract: The present invention relates to a method of estimating a finger movement direction of a finger, comprising the steps of: a) acquiring a reference fingerprint image; b) acquiring at least one candidate fingerprint image at each acquisition time in a time sequence of acquisition times; c) determining, for each of the acquisition times, a match parameter value for each of a plurality of candidate finger movement directions, the match parameter value being indicative of a correlation between a reference fingerprint image portion and a candidate fingerprint image portion corresponding to displacement in the candidate finger movement direction; d) determining, for each of the candidate finger movement directions, a local extremum match parameter value indicating a maximum correlation for the time sequence of acquisition times; and e) estimating the finger movement based on an evaluation of the determined local extremum match parameters.

Abstract: A method for evaluating an individual fingerprint template by using a remote dataset, comprising the steps of capturing a fingerprint representation by a fingerprint reader on a device, extracting significant data from the captured fingerprint representation, thereby creating an individual fingerprint template for the captured fingerprint representation, transmitting the individual fingerprint template from the device to a remote dataset comprising a plurality of fingerprint templates, determining an impostor score distribution for the individual fingerprint template, determining a security threshold for the individual fingerprint template, and transmitting the determined security threshold to the device. The advantage of the invention is that an individual security threshold can be set for a user, which will improve the FAR distribution of a device.

Abstract: The present invention relates to a method of enrolling a fingerprint of a user's finger, by means of an elongated fingerprint sensor having a sensing area being smaller than the fingerprint. The method comprises the steps of instructing the user to place the finger on the fingerprint sensor with a first finger orientation for achieving a first angle between a longitudinal finger axis and a longitudinal sensor axis; acquiring a partial fingerprint image for the first orientation; instructing the user to place the finger on the fingerprint sensor with a second finger orientation for achieving a second angle; acquiring a partial fingerprint image for the second finger orientation; and forming a fingerprint enrollment representation for the finger based on the partial fingerprint images for the first and second finger orientations and a relation between the first angle and the second angle.
