This document discusses biometric authentication systems. It defines biometrics as measuring life to identify individuals by physical characteristics like fingerprints, face recognition, or voice. A biometric authentication system detects identities using specific body parts. It is more secure than passwords since physical traits cannot be forgotten, shared, or stolen. The document outlines the benefits of biometric systems, such as convenience, security, and accountability, and describes some applications in institutions like schools, banks, and government agencies. However, biometric systems have drawbacks like potential privacy issues and high costs to implement accurate identification technologies.

3. Bio-metrics
Authentication System

4. Basically Bio means “Life”.
While Metro means “To Measure”
Biometric means identifying an individual based
upon his/her physical characteristics.

5.  While authentication is a process of giving
some one identity so that he/she can access that
particular application or data.
 For example…giving identity card to a students
of university.

6. So biometric authentication system is a system
that detect the identity of a person by using the
specific part of human body.
For E.g By using finger prints, or detect the
identity bye using the face of human or voice
etc…

7.  By using passwords or pin codes.
 By using smart cards or any other form of cards.
 By using biometric authentication system.

8.  Convenient
 Passive identification
 More secured
 Password are not user-friendly

9.  No body theft your identity
 impossible to hack
 no chance to share with others
 No need to remember like password
 very secure

10.  It is a method of recognizing an individual is
based on two main characteristics
 Physical characteristics related to physical
shape of body For..e.g. Face recognition , iris
recognition , hand geometry and etc….
 Behavioral characteristics related to behavior of
person For..e.g. voice pitch , speaking style ,
signature and etc….

11. Steps
 Capturing
 Pre-processing
 Feature extraction
 Template matching
 Matcher / Comparison
 Application device

12.  A scanning
 A software which converted scanned
information into digital forms and compares on
some matching points
 A database that stores biometric features for
further comparison.

13.  There are some institutions where biometric
system used
 NADRA offices
 Defense system
 Educational institutions
 Telecommunication
 Forensic labs
 Attendance

14.  Time saving
 Accurate Identification
 System Accountability
 User friendly
 Security

15.  Convenience
 Increase in return on Investment

16.  Privacy
 No hacking threat
 Impossible to change
 Free of cost for individual

17.  Improvement in attendance of school colleges
and universities.
 Transparent elections.
 Improvement in overall law and order situation.
 Reduce frauds in society
 Enhance the security of your computers mobile
phones ATMs etc.

18.  Over all this system of authentication is not
cheap, good and top quality biometric
authentication system is costly.
 Some time system unable to detect the identity
of user.
For e.g: some time system fail to detect the
identity of user by using its face or voice.

19. Biometric system is no doubt is very important
and useful system by using biometric system we
will be able to solve some basic issues from our
country. For example…
 We will be able to held pure and transparent
election in our country.
 Control over terrorism.
 Resolve attendance issues.
so if we use biometric system for authentication
we will be able to resolve these types of serious
issues.

20. as well the greater strength of biometric system is
it that they does not change over time once
system provide you identity it is not been able
to change.
So it is much better than other security
mechanisms.
