Biometrics Authentication Technology Navin Kumar 09EAXEC075 Submitted By: Navin Kumar

Three main types of authentication available today are: Something you know, like a password, PIN, or code. Something you have, like a swipe card, smart card, token, or key. Something you are, which is biometrics.

What is a biometric? Biometrics are automated methods of identifying a person or verifying the identity of a person based on a physiological or behavioural characteristic. 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: Voice Gait Keystroke dynamics Voice Gait Signature dynamics

new biometric sample is requested. Biometrics Process new biometric sample is requested. No Quality Sufficient? Signal Processing, Feature Extraction, Representation Biometric Data Collection Transmission Yes Generate Template Database Template Match Yes Decision Confidence? No

Fingerprint Recognition steps: Database

Face recognition process: Extraction of face features Input face image Extraction of face image Positive Database Negative

Iris Identification Steps: Input of face image Recognition of iris pattern Detection of eye regions Put iris in focus Accept Database Reject

Vein Recognition System: The output picture Generate veins structure Input of palm picture Match Database Not match

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, Biometric trait the pressure exerted by the person while signing, the variations in the speed with which different parts of the signature are written.

Aadhaar One-time standardized Aadhaar enrollment establishes uniqueness of resident via ‘biometric de-duplication’ Only one Aadhaar number per eligible individual Online Authentication is provided by UIDAI Demographic Data (Name, Address, DOB, Gender) Biometric Data (Fingerprint, Iris, Face) Aadhaar :subject to online authentication is proof of ID Aadhaar enrollment / Update = KYC Aadhaar No. Issued, stored in Auth. Server “Verification” of KYC (Authentication)

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. Missing body part problem. False acceptances and rejections. The scanning of eye is fearful. The nervousness that people feel about the scanners identification.

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