THREE MAIN TYPES OF AUTHENTICATION AVAILABLE TODAY ARE: Something you know like a password, PIN or code. Something you have, like token, or key. Something you are, which is biometric..

BIOMETRICS AS AUTHENTICATION Authentication depends on What you have What you know What you ARE!.

What is biometric?. Biometrics are automated methods of identifying a person or verifying the identity of a person based on a physiological or behavioral characteristics. Most definitive, real-time tool available today. Can be combined with other tools to form more secure, easier to use verification solutions. Recognizes individuals definitively..

characteristics. The common physical characteristics are: Fingerprint Face Retina Iris Vein pattern Hand and finger geometry.

characteristics. Behavioral characteristics are: Keystroke dynamics Voice Gait Signature dynamics.

Biometric authentication process. Acquisition Creation of Master characteristics Storage of Master characteristics Acquisition(s) Comparison Decision.

Fingerprint recognition steps. Image acquisition.

Vein recognition system. Input of palm picture The output picture Match Not match Generate veins structure Database.

Signature verification process. The angle at which the pen is held, The number of times the pen is lifted, The time it takes to write the entire signature, The pressure exerted by the person while signing, The variations in the speed with which different parts of the signature are written..

Applications area of biometric. Enterprise and E-government services National Security Airport, Bank, Offices Recently implemented in ATM, Voting Machine Internet Banking Biometric time attendance system.

Advantages of biometrics. Uniqueness Universality Permanence Measurability User friendliness Accuracy Comfort.

Disadvantages of biometrics. Costly. Facial imaging can also hinder accurate identifications.

CONCLUSION. Not perfect yet. Successful applications. Decreasing cost and increasing convenience. Increasing both privacy and identity security. The field of biometrics is evolving. Benefit from this technology..
