FAST FINGERPRINT SEARCHING METHOD AND FAST FINGERPRINT SEARCHING SYSTEM

WIPO Patent Application WO/2010/069166

A1

A fast fingerprint searching method and fast fingerprint searching system are provided. Fingerprint templates in the fingerprint template library are classified into templates with core points and templates without core points. The fast fingerprint searching method involves: collecting the fingerprint templates needed to be compared and finishing the extraction of on-site fingerprint features; judging that the extracted on-site fingerprint features are on-site fingerprint features with core points or on-site fingerprint features without core points; respectively comparing the on-site fingerprint features with all the templates with core points in the fingerprint template library if they are on-site fingerprint features with core points; respectively comparing the on-site fingerprint features with all the templates without core points in the fingerprint template library if they are on-site fingerprint features without core points.
