FINGERABDRUCKSVERIFIKATIONSMETHODE UND -SYSTEM

摘要

A method to conduct fingerprint verification provides a sector distribution (101) based on the position (102) and angle (110) of every minutiae vector, wherein the number (0 in 106, 1 in 107 and 2 in 108) of further minutiae vectors of the template in any sector (105) of the sector distribution (101) is determined and a feature vector is generated for every minutiae vector of both templates (query and reference). The two feature arrays are matched by calculating the scalar product for every combination of said vectors generating a matrix. Mated pairs of minutiae from the first second template are found by searching the maximum element in every column of the matrix finally issuing a value representing identification information of the fingerprint. Additionally a false finger identification method and a fingerprint verification system are disclosed.
