What is BiometricsDefinition:
“Automated measurement of Physiological and/or behavioral characteristics to determine or authenticate identity”
Biometrics is a security solution based on something you know, have, and are:
KnowPassword, PIN
HaveKey, Smart Card
AreFingerprint, Face, Iris
Physiological and/or behavioral characteristics
1. Behavioral:User speaks.Signs name
2. Physiological:FingerprintHandEyesFace
determine or authenticate identity
Verification Systems
› More accurate.› Less expensive.› Faster.› More limited in function.› Requires more effort by user.
Why Biometrics? Passwords are not reliable.
› Too many › Can be stolen› Forgotten

1. Cell phones, Laptops, Work Stations, PDA & Handheld device set.
2. Door, Car, Garage Access
3. ATM Access, Smart card

Biometrics-enabled Identification Applications
1. Criminel Trackinge.g. Fingerprints, DNA Matching
2. Car Park Surveillance
3. Frequent Customer Tracking
How biometric work Biometrics work by recording and comparing biometric characteristics.
There are two type for biometric recognition
1. Identification2. Verification
IdentificationIt mean identify and analyze the humane unique characteristic.
It can divided in two types
1. Behavioral2. Physiological
Finally recognize whether that information are real
E.g.- In ATM machine verify your pass word or finger mark & If it is true then you can withdraw money.
Bio metrics devices
There are many types of bio metrics devices
Commonly using 5 types of devices1. Iris scanner2. Finger print scanner3. Facial Biometrics4. Voice Recognition5. Other
Finger print Scanner
Private and government sectors is using Finger print devices
Earlier days used ink and paper method
Facial Biometrics
Each and every persons have different and unique face.
Use series of images for identify persons
Voice Recognition
Some computer systems have voice recognition method
Voice recognition is not the same as speech recognition, it is speaker recognition
Biomatrix.
. .
ADVANTAGES A long-used method
that is familiar and generally quick perform. Fingerprints are unique. A set of 10 prints yields highly accurate results. Cheap and easy to use.
DISADVANTAGES Some people have
poor prints because of injury, age, disease or occupation. Requires physical contact with a sensor and may have negative connotations because of use by law enforcement.
FINGERPRINTS
HAND GEOMETRY
. .
ADVANTAGES. Fast and easy to
use. Rugged and works well outdoors.
DISADVANTAGES. Not suited for
picking someone out of a large group. Sensors are large and relatively expensive
SPEECHVERIFICATION
.
ADVANTAGES.
Can use standard microphone or telephone handset and existing telephone lines.
DISADVANTAGES
Background noise, illness or stress can affect voice samples. Most accurate if similar instruments capture voice samples at enrollment and verification points. Not suited for picking someone out of a large group.
