Abstract

Biometric systems based on a single source of information (unimodal biometric systems) face challenges such as lack of uniqueness and non- universality of the chosen biometric trait, noisy data and spoof attacks .This paper looks at the position of unimodal biometrics in the field of computer security, the challenges of unimodal biometric authentication systems and their possible solutions. It also introduces a more systematic view of the process of unimodal biometric authentication - a layer model (of the unimodal biometric authentication process, its application and possible causes of biometric system failures. Finally, the paper suggests areas of use of biometric systems.
