METHOD AND DEVICE FOR UPDATING SEQUENCE OF FINGERPRINT TEMPLATES FOR MATCHING

摘要

A method for updating a sequence of fingerprint templates for matching is disclosed, comprising: acquiring a fingerprint image; comparing the fingerprint image with a preset fingerprint template selected from N preset fingerprint templates stored in advance, sequentially in a predetermined sequence of the N preset fingerprint templates for matching, each preset fingerprint template corresponding to a matching score; adjusting the matching score corresponding to an ith preset fingerprint template, when the fingerprint image matches the ith preset fingerprint template; and sequencing the N preset fingerprint templates in a sequence of the matching score corresponding to the respective preset fingerprint template from high to low, to obtain a updated sequence of the N preset fingerprint templates. A next acquired fingerprint image is compared with the preset fingerprint templates sequentially in the updated sequence, to improve the efficiency. A device for updating a sequence of fingerprint templates for matching is also disclosed.
