Biometric identification process and system utilizing multiple parameters scans for reduction of false negatives
First Claim
1. An individual recognition system comprising:
- a storage medium storing as biometric data a plurality of physical characteristics of a user;
reading means for extracting from the user biometric data representing one of the physical characteristics stored by said storage medium;
comparison means for determining whether or not the extracted biometric data represents the same physical characteristic as corresponding stored biometric data obtained from said storage medium; and
control means for instructing said reading means to extract from the user additional biometric data representing a different physical characteristic stored by said storage medium, depending on the determination by said comparison means.

Abstract
A system for verifying that a card possessor is the authorized card owner compares scanned fingerprint data with fingerprint data encoded on an optical card. More than one of the person'"'"'s fingerprints are encoded on the card, and the process of identification of the card possessor involves the random selection of separate fingerprints for scanning and comparison against the encoded fingerprints. A card reader/writer reads fingerprint characteristic information from an optical card inserted therein and a processing unit, connected to a fingerprint scanner and card reader/writer extracts from the scanned fingerprint certain well known indicators, and matches the recorded fingerprint characteristic data with the scanned fingerprint characteristics to establish identity therebetween.

13. An individual recognition system comprising:
-
a portable storage medium storing as biometric data a plurality of physical characteristics of a user; reading means for extracting from the user biometric data representing one of the physical characteristics stored by said storage medium; comparison means for determining whether or not the extracted biometric data represents the same physical characteristic as corresponding stored biometric data obtained from said storage medium and outputting a positive comparison result if a match occurs; and control means for instructing said reading means to extract from the user additional biometric data representing a different physical characteristic stored by said storage medium if said comparison means does not output a positive test result. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A personal identification method using a data storage medium containing previously stored biometric data representing a plurality of physical characteristics of a user, the method comprising:
-
a first extracting step of extracting from the user biometric data representing one of the physical characteristics stored by the storage medium; a determining step of determining whether or not the extracted biometric data represents the same physical characteristics as corresponding stored biometric data obtained from the storage medium; and a second extracting step of extracting from the user additional biometric data representing a different physical characteristic stored in the storage medium depending on the determination at said determining step. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method for identifying one person from a plurality of persons, said method comprising the steps of:
-
gathering identification data representing a plurality of physical characteristics from each of the plurality of persons; storing the gathered data; and providing apparatus for repeatedly obtaining different identification data representing respective ones of the plurality of physical characteristics from a person presenting himself or herself and comparing obtained identification data with stored data until the obtained identification data matches stored identification data for the respective physical characteristic. - View Dependent Claims (35, 36, 37)
