Fusion of Iris & Fingerprint Biometric for Security Purpose
Prashant Lahane, S. R. Ganorkar · 2012
Basic aim of a biometric system is automatically discriminate between subjects as well as protect data. It also protects resources access from unauthorized users. We develop a biometric identification system that represents a valid alternative to conventional approaches. In biometric system physical or behavioral traits are used. A multimodal biometric identification system aims to fuse two or more physical or behavioral traits. Multimodal biometric system is used in order to improve the accuracy. Multimodal biometric identification system based on iris & fingerprint trait is proposed. Typically in a multimodal biometric system each biometric trait processes its information independently. The processed information is combined using an appropriate fusion scheme. Successively, the comparison of data base template and the input data is done with the help of Euclidean-distance matching algorithm. If the templates are matched we can allow the person to access the system. We are going to check FAR & FRR with different threshold level. Multimodal biometric system provides optimal False Acceptance Rate (FAR) & False Rejection Rate (FRR), thus improving system accuracy & reliability.
