Abstract: A method of classifying a finger touch in respect of a finger pressure on a surface of a fingerprint sensor, comprising the steps of: receiving, on the surface of the fingerprint sensor, a finger having a fingerprint topography; acquiring a first time-sequence of fingerprint images; determining a reference value of at least one image-related parameter indicative of a compression of the fingerprint topography, based on at least one fingerprint image in the first time-sequence of fingerprint images; acquiring a second time-sequence of fingerprint images; determining a test value of the at least one image-related parameter based on at least one fingerprint image in the second time-sequence of fingerprint images; and classifying the finger touch based on a relation between the test value and the reference value.

Abstract: A method of determining a physical property of a finger using a sensor comprising a two-dimensional measuring arrangement including a plurality of measuring elements, each defining a measuring element position in the measuring arrangement, and each comprising a finger electrode spaced apart from the finger by a dielectric structure. For each measuring element position, the method comprises the steps of performing a first sensing operation using a first capacitive configuration, acquiring a first measurement value for the first capacitive configuration, performing a second sensing operation using a second capacitive configuration, acquiring a second measurement value for the second capacitive configuration. The physical property of the finger is determined based on the first and second measurement values for each measuring element position.

Abstract: A method of determining a representation of a physical property of a finger using a finger sensing system comprising a two-dimensional measuring arrangement including a plurality of measuring elements, each defining a measuring element position in the measuring arrangement, and each comprising a finger electrode spaced apart from the finger by a dielectric structure. For each of the measuring element positions, the method comprises providing a measuring configuration in which the finger electrode of a sensing measuring element defining the measuring element position exhibits a sensing finger electrode potential; the finger electrode of a first different measuring element exhibits a first different finger electrode potential; and the finger electrode of a second different measuring element exhibits a second different finger electrode potential; acquiring a measurement value based on a sensing signal; and determining the representation of the physical property of the finger based on a plurality of measurement values.
