3. Introduction
The term “biometric” is derived from the Greek words bio (life)
and metric(to measure).
For our use biometrics refers to technologies for measuring and
analysing person's physiological or behavioural characteristics
These characteristics are unique to individuals hence can be used
to verify or identify a person.

5. Finger Recognition
 A fingerprint sensor is an electronic
device used to capture a digital image of
the fingerprint pattern.
 The captured image is called a 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.
 This is an overview of some of the more
commonly used fingerprint sensor
technologies.

6. Facial Recognition
 Capture image
 Find face in image
 Extract features
(store template)
 Compare templates
 Declare matches

measurement of many dimensions of the hand and
fingers.

8. Iris Recognition
Iris scanning measures the iris
pattern in the colored part of the
eye,

9. Speaker / Voice Recognition
Voice or speaker recognition uses vocal
characteristics to identify individuals using a pass-
phrase.
 A telephone or microphone can serve as a sensor,

10. Signature Verification
An automated method of measuring an individual’s
signature.
This technology examines speed,direction, and
pressure of writing; the time that the stylus is in and out
of contact with the “paper’’.

11. Prevent unauthorized access to ATMs, Cellular phones
Desktop PCs
Criminal identification
In automobiles biometrics can replace keys with keyless
entry devices
 Airport security

13. Conclusion
Biometric is an emerging area with many
opportunities for growth.
Possibly in the near future, you will not have
to remember PINs and passwords and keys in
your bags or pockets will be things of the past.
