• Something you know, like a password, PIN,
• Something you have, like a swipe card, smart
card, token, or key.
• Something you are, which is biometrics.
Three main types of authentication
available today are:
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.
The common Physical characteristics are:
Hand and finger geometry
Behavioral characteristics are:
new biometric sample is requested.
Fingerprint Recognition steps:
Face recognition process:
I ris I dentification Steps:
Input of face
Put iris in focus
Vein Recognition System:
Input of palm
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.
Signature Verification Process
One-time standardized Aadhaar enrollment establishes uniqueness of resident via
• 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,
stored in Auth. Server
“Verification” of KYC
Applications Area of Biometric
Enterprise and E-Government services
Airport, Bank, Offices
Recently implemented in ATM, Voting Machine
Biometric Time Attendance System
Advantages of biometrics
Disadvantages of Biometrics
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
Not perfect yet.
Decreasing costs and increasing convenience.
Increasing both privacy and identity security.
The field of biometrics is evolving.
Benefit from this technology .
