1. A method for identifying fingerprints, comprising:
capturing a fingerprint by a fingerprint sensor and identifying matching pairs of minutiae between the captured fingerprint and a reference fingerprint;
calculating a first matching result based on the minutia matching pairs;
identifying minutia surrounding features for each minutia of the captured fingerprint in the minutia matching pairs;
determining, for each minutia in the minutia matching pairs, whether the minutia surrounding features of the captured fingerprint match with minutia surrounding features of the reference fingerprint;
calculating a second matching result based on a result of the determining;
adjusting the first matching result based on the second matching result to generate an adjusted matching result; and
generating an identification result based on the adjusted matching result.
