A QUICK MATCH ALGORITHM FOR BIOMETRIC DATA

摘要

A method (10) for matching a biometric user template to at least one multi template is provided. Each multi template is formed by a group of sub templates each representing an area of an associated biometric object of a person. The method comprises a) determining (11) a first matching score between at least one of the sub templates for at least one of the multi-templates and the user template; b) determining (12) an order of the sub templates based on their first matching score and which multi template they belong to; c) processing (13) at least one of the sub templates successively based on the predetermined order, wherein said processing comprises for each sub template: d) determining (131) a second matching score between the sub template and the user template, e) comparing (132) the second matching score to a threshold score, and g) generating (133) a signal indicating a match if the second matching score is above the threshold score.
