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
Automated measurement” No human involvement. Comparison takes place in Real-Time.
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?
Why Biometrics?
Passwords are not reliable.› Too many › Can be stolen› Forgotten

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

Biometrics-enabled Identification Applications
1. Criminel Trackinge.g. Fingerprints, DNA Matching
2. Car Park Surveillance
3. Frequent Customer Tracking
How biometric work
How biometric work
Biometrics work by recording and comparing biometric characteristics.
There are two type for biometric recognition
1. Identification
2. Verification
Identification
It mean identify and analyze the humane unique characteristic.
It can divided in two types
1. Behavioral
2. Physiological
Identify Methods
Fingerprint
Face Recognition
Signature
Iris Scan
Hand
Biometrics Verification
Firstly collects data and information convert to digital format.
Then process the information and keep it. Because that need to compare with new biometric data
After check and compare with new biometric data with data storage.
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
Bio metrics devices
There are many types of bio metrics devices Commonly using 5 types of devices
1. Iris scanner
2. Finger print scanner
3. Facial Biometrics
4. Voice Recognition
5. Other
iris scanner
This scanner use for identify humens iris
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
Advantages and Disadvantages
Bio
matrix.
. .
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.
