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

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

8. Fingerprint Recognition steps:
Database

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

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

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

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 .
