First of all, Thank you for giving this opportunity of presenting my knowledge with you all, hope this is helpful to learn something regarding biometric technology

2. Overview
 What is Biometrics?
 Why Biometrics?
 Types of Biometric Recognition
 Applications of Biometric Systems
 Advantages
 Disadvantages

3. What is Biometrics?
Automated method for recognizing individuals based on
measurable biological and behavioral characteristics. The
term biometric is basically derived from the Greek word
“Bio” means life and “metric” means to measure

4. Why Biometrics?
 Biometrics cannot be lost , stolen or forgotten. The biometric
is consistent and permanent.
 Biometric recognition provides a strong link between an
individual and a claimed identity
 Biometric itself cannot be socially engineered, shared or
used by others

5. Types Of Biometrics
 Fingerprint Recognition
 Facial Recognition
 Voice Recognition
 Iris Recognition
 Retina Recognition

6. Finger Print Recognition
A fingerprint sensor is an electronic device used to
capture a digital image of the fingerprint pattern .
This captured image called live scan this live scan
is digitally processed to create a biometric
template(a collection of extracted features) which
is stored and used for matching.

7. Facial Recognition
 A Face recognition is the way to comparing
selected facial features from the image and
the face database
 Face recognition can also identify slightly
different placing of the eyebrows , The
width of eyes with the position/ size/shape.

8. Voice Recognition
 Voice recognition is with the help of special
voice recognition software , tiny differences
in each person’s voice can be noted , tested
and authenticated to only allow access to the
person that has the right tone , pitch , and
volume of voice.

9. Iris Recognition
 Iris recognition measures the iris
pattern of the eye i.e. the colured
part of the eye that surrounds the
pupil.
 The iris recognition analyzes
features like rings , furrows and
freekles existing in the coloured
tissue .

10. Retina Recognition
 Retina recognition is used to map
the unique patterns of persons
retina.
 Retinal biometrics is a sophisticated
means for identifying People by the
pattern of blood vessels on the
retina.

11. Applications
 Database Access
 Recording time and Attendance
 Banking/credit
 Computer/network
 Enrollments
 Immigration purposes

12. Advantages
 User-friendly systems
 Reduce fraud
 Uniqueness
 Increase accuracy
 Better security and authenticity

13. Disadvantages
 Lack of standardization
 Costly
 False acceptance and rejections
 While the reliability and the accuracy of biometric
devices continues to improve

15. Conclusion
 Biometrics is a very interesting and exciting field that
has be growing exponentially in recent years.
 The wide variety of physically unique traits our
bodies give us will soon allow us to live in very
secure password-less world.
