Comparison of Various Biometric Methods

Biometrical authentication is the process of making sure that the person is who the user claims to be. Physiological biometric traits include face and retina structures, fingerprint (whorls minutia), hand geometry, iris (pattern), ear (structure of the cartilaginous tissue of the pinna), palm vein and DNA structures etc where as behavioral biometric traits include gait patterns, signatures, keystroke and odor etc. Biometric is a very accurate and reliable method as compared to traditional knowledge based (e.g., passwords) and token based (e.g., ID cards) mechanisms.
