The document discusses biometrics as a method of authentication, highlighting three main types: knowledge-based, possession-based, and inherent characteristics. It details various biometric identifiers, such as fingerprints and facial recognition, elaborates on the Aadhaar system for identity verification in India, and outlines the advantages and disadvantages of biometrics. The conclusion states that while not yet perfect, biometrics are evolving and becoming more secure and convenient.

2. 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.

3. 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.

4. Characteristics
The common Physical characteristics are:
 Fingerprint
 Face
 Retina
 Iris
 Vein pattern
 Hand and finger geometry

5. Characteristics
Behavioral characteristics are:
 Keystroke dynamics
 Voice
 Gait
 Signature dynamics

12. 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.

13. 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 = Aadhaar No. Issued, “Verification” of KYC
KYC stored in Auth. Server (Authentication)

14. 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

15. Advantages of biometrics

16. 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.

17. 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 .
