Fingerprint Verification Method

Described is a personal verification technique which uses one or more fingerprints to establish verification. Typical applications could be personal verification for admittance to secure areas, or access to computer terminals.

In this system, the person desiring admittance supplies encoded information which describes certain characteristics of his fingerprint or prints. These data could be read from a magnetic stripe card, for example, or held in a large central electronic store and retrieved when required by entrance of a code number by the person requesting admittance. The person's fingerprint is scanned and the characteristics gathered in this manner are compared with the data which represents the individual. The degree of match can be set, so that the probability of false acceptances corresponds to the degree of reliability to which the system must operate.

Conventional scanning of entire fingerprints results in much more information than is required to usefully separate individuals within a limited (say several hundred) set of people. Described is a technique by which only a few selected small areas of a fingerprint need be considered to obtain a high degree of system accuracy, and can be achieved with a great reduction in the amount of data processing normally required for a full fingerprint analysis.

In the embodiment described, three small areas of the fingerprint are chosen on which to make the accept or reject decision. The significant characteristics of an individual contained within these three areas are originally obtained from a reference print, and encoded either on the magnetic card or ente...
