Analysis of various Biometric Techniques

Biometrics is automated methods for identifying a person or verifying the identity of a person based on a physiological or behavioral characteristic has the capability to reliably distinguish between an authorized person and an imposter. Since biometric characteristics are distinctive, can not be forgotten or lost, and the person to be authenticated needs to be physically present at the point of identification, biometrics is inherently more reliable and more capable than traditional knowledge-based and token-based techniques. Using biometrics for identifying human beings offers some unique advantages. Biometrics can be used to identify you as you. Biometrics holds the promise of fast, easy-to-use, accurate, reliable, and less expensive authentication for a variety of applications. This paper provides an overview of the different biometric technique with some advantages and disadvantages. Than we will try to find out which technique is more reliable and secure. Keywords— Biometric, False Reject Rate (FRR), False Acceptance Rate (FAR).
