SYSTEM FOR SEARCHING USER USING MULTIPLE BIOMETRICS AND METHOD THEREOF

摘要

A system and a method for searching a user with multiple biometric recognitions are provided to remove recognition error occurring in a process for fusing matching points, which are a recognition result of more than two single biometric recognition systems. Fingerprint and face information databases(103,106) store a plurality of biometric information received from a plurality of users. Fingerprint and face distribution estimators(107,108) estimate probability distribution by using a cumulative distribution function for biometric information stored in the fingerprint and face information databases. Fingerprint and face searchers(113,116) search a plurality of biometric information of a target user from the fingerprint and face information databases and assigns a matching score to each biometric information by determining matching between the biometric information of the target user and the biometric information stored in the fingerprint and face information databases. A fuser(117) fuses the matching points based on CBF(Cumulative Bayes Fusion) by referring to the estimated probability distribution, and extracts a search result for the target user from a fusion result.
