Multi Biometric Model for Authentication Method
In recent years, biometric authentication has seen considerable improvements in reliability and accuracy with some biometrics contributes reasonably good overall performance. In biometric based systems for identity verification, static, (and/or) dynamic biometric measures may be used as personal passwords. However, even the most advanced biometric systems are still facing numerous problems, some inherent to the type of data and some to the methodology itself. Each biometric system must perform four basic tasks i.e. acquisition, feature extraction, matching and decision making.
