Designing a Biometric (Finger) Using Multispectral Imaging Biometric Authentication Measures for Enhancing ATM Security in Nigeria

Among all the biometrics, fingerprint based identification is one of the most mature and proven technique. Surface fingerprint characteristics, can be obscured during imaging by moisture, dirt or wear which has become a challenge. Multispectral imaging technology, on the other hand, was specifically developed to overcome the fingerprint-capture problems commonly found with conventional fingerprint systems in less-than-ideal conditions. This technology uses multiple sources and types of light and advanced polarization techniques to extract unique fingerprint characteristics from both the surface and subsurface of the skin. This paper focuses on vulnerabilities and the increasing wave of criminal activities occurring at Automated Teller Machines (ATMs) where quick cash is the prime target for criminals rather than at banks themselves. A biometric measure as a means of enhancing the security for banking system for both customer's & bankers also. We also proposed a total elimination of cards as the finger can serve as both password and access card.
