Reliability of Identification Based on Fingerprints in Dual Biometric Identification Systems

Abstract:

At present, the development of biometrics is a widely discussed topic. This research discusses the reliability of the most used category - identification using fingerprints. There are many of these types of systems. The most affordable, and therefore the most common alternative is one that identifies users using an optical sensor. Testing was conducted on two scanners only for fingerprints, and on two systems that recognize users via their fingerprints and also through a facial image. The conclusions from the measurements were that reliability was mainly affected by the characteristics of the scanners, in particular whether the scanner identifies only based on the fingerprint, or in combination with another biometric method. Due to the fact that with combined systems manufacturers focus only on one identification circuit – usually the most modern - and not the potentially safest, i.e. a fingerprint, the results show that it is much easier to sabotage dual biometric identification devices than those that identify solely on the basis of a fingerprint. Reliability values ​​greatly exceed the values specified by the manufacturer. The measurements show that there is a need to continuously improve dual biometric identification systems.
