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: A computer-implemented method of performing fingerprint based authentication from matching local features represented by binary features which can be matched in an efficient implementation in one or both of software and hardware by computing Hamming distances between the binary features. A local feature in a verification image is said to be matching with a local feature in an enrolment image if the Hamming distance between the binary features falls below a pre-determined threshold. The computer-implemented method retains information about the similarity of local features in the two images and utilities it in an efficient way with the objective of improving fingerprint recognition rates and enabling finger liveness detection. In an aspect a normalized feature similarity distribution is generated as part of the representation in recognition and liveness detection.

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.
