A Review On Physiological Attributes Based Biometric Authentication

This study involves the review of various types of physiological biometric authentication systems. Today, security is the most important concern. Biometric authentication technologies are becoming more popular as a method of verifying people’s identities. Biometric systems also add a layer of convenience for the user. They make it unnecessary for the user to “remember” numerous passwords for various apps, for example. A biometric system that uses a single biometric trait to identify persons must deal with issues such as spoof attacks, trait non-universality, substantial intra-class variability, limited degrees of freedom, and noisy data. Multi-modal biometrics, on the other hand, can be quite useful in this case because they do not have the same set of issues as unimodal biometrics. The performance of multimodal biometric systems, as they are known, has improved dramatically.
