4. Information Security is concerned with the
assurance of confidentially , integrity and
Availability of information in all forms
 This is the ancient Greek word:
bios=“life” and metron=“measure”

5. DEFINITION
Biometrics refers to the automatic identification
of a person based on his/her physiological or
behavioural characteristics

6. Terms of biometrics
 Recognition
 Identification
 Verification

7. CHARACTERISTICS

8. Facial recognition
1. Capture image
2. Find face in image
3. Extract features(store
templates)
4. Compare templates
5. Declare matches

9. Fingerprint recognition
This includes the following:
1. Small ridges
2. Spaces between two
temporarily divergent ridges
3. Spurs(a notch protuding from
a ridges)
4. Bridges

10. Hand geometry
Hand Geometry is an
automated measurement
of many dimensions of
hand.

11. Iris scanning
Iris scanning measures
the iris pattern in the
coloured part of the eye

12. VOICE RECOGNITION
Voice Recognition uses
vocal characteristics to
identify individuals using
a pass phrase.
Telephone or
Microphone can serve as
a sensor.

13. SIGNATURE VERIFICATION
An automated method of
measuring an individual’s
signature.
This technology examines
speed , direction and
pressure while writing.

14. KEYSTROKE IDENTIFICATION
It is an automated method of
examining an individual’s key
strokes on keyboard.
This Technology examines
speed , pressure and total time
taken to type particular
words.
Also the time elapsed
between hitting certain keys.

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

16.  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.
