The use of biometrics has found its way into many aspects of our daily lives and is slowly spreading to places we hardly considered before. The intent of biometrics is to identify a person in a way that is 100% accurate and cannot be stolen or compromised. Some biometrics, such as fingerprint recognition, have been in use for years. Newer biometrics, such as retinal scan and capillary mapping, were only possible once technology advances made these authentication applications feasible.
