In computer systems, there is an urgent need for accurate authentication techniques to prevent unauthorized access. Authentication is the process of confirming the correctness of the claimed identity Many computers that store critical information are vulnerable to unauthorized access because of weak authentication. In some cases, the safety of the public can be at risk, such as in the case of a multi-billion dollar passenger-screening system defenceless against terrorists with forged security badges. Traditional authentication techniques such as the ubiquitous username / password method are inadequate for personal identity since they can only provide proof of possession and/or proof of knowledge. Only biometrics, the authentication of individuals using biological identifiers, can offer true proof of identity. Current research suggests that multimodal biometric systems, those that use more than one biological identifier, can improve the accuracy of biometric systems. This improvement in accuracy depends on critical factors in design, implementation and security. This paper explains each of these critical factors so the increase in accuracy observed in current research can be achieved in real-world applications.
