Providing security has become a challenging factor in today’s advanced computerized engineering and Technological environment. Traditional methods like memorizing passwords, carrying ID cards have their own draw backs. Biometric Authentication has become more and more reliable, secured and most convenient tool. Simply Biometrics refers to establishing identity based on the physical and behavioral characteristics of an individual such as face, fingerprint, hand geometry, iris, keystroke, signature, voice, etc. Biometric systems offer several advantages over traditional authentication schemes. They are inherently more reliable than password-based authentication as Biometric traits cannot be lost or forgotten.This paper explains various Biometric Traits which helps in authentication process and explain how iris is more reliable,when compared with other Biometrictraits.
