1. A method for computer-based processing a template minutia set of a fingerprint, comprising the following steps:
a) providing the template minutia set comprising template minutiae and a template interest region,
b) providing an input minutia set according to an input fingerprint comprising input minutiae and an input interest region,
c) matching the input minutia set with the template minutia set, thereby determining matching template/input minutiae and non-matching template/input minutiae, and
d) determining an updated template minutia set which comprises the adding of non-matching input minutiae inside the termplate interest region to the termplate minutia set if the input minutia set and the template minutia set are known to originate from a same finger or their matching result is higher than a matching threshold.
