A Review of Multibiometric System with Fusion Strategies and Weighting Factor

Biometric is a technology for verification or identification of individuals by employing a person’s physiological and behavioural traits. Although these systems are more secured compared the traditional methods such as key, smart card or password, they also undergo with many limitations such as noise in sensed data, intra-class variations and spoof attacks. One of the solutions to these problems is by implementing multibiometric systems where in these systems, many sources of biometric information are used. This paper presents a review of multibiometric systems including its taxonomy, the fusion level schemes and toward the implementation of fixed and adaptive weighting fusion schemes so as to sustain the effectiveness of executing the multibiometric systems in real application.
