BIOMETRICS SECURITY SYSTEM
INTRODUCTION
Biometrics is a rapidly evolving technology
Facilitates the automatic identification based on physical or behavioral characteristics
Eliminates the need to memorize a password or carry some form of token
WHAT IS A BIOMETRIC ?
Science and technology of measuring and statistically analyzing biological data that is represented in human by
patterns unique to every individual
Figure describing the process involved in using the biometric system
SUBSYSTEMS OF BIOMETRIC MODEL
DATA COLLECTION
TRANSMISSION
SIGNAL PROCESSING
DECISION MAKING
DATA STORAGE
TYPES OF BIOMETRIC SYSTEM
Fingerprint Verification Hand Geometry
Retinal Scanning
Iris Scanning
Facial Recognition
Signature Verification
Voice Verification
DETAIL ANALYSIS OF IRIS SCANNING
Iris scan takes about 30sec & 2sec for verification
A camera located at about 3 feet focuses on & scans iris from one side
This scan is converted into a template
Only phase information is used for recognizing iris as amplitude information is depends on extraneous
factors
A IRISCODE Sample Iris scanning enabled Atm
Authenticam used for iris scanning
ADVANTAGES OF IRIS SCANNING
Iris pattern posses high degree of randomness,variability & uniqueness
Patterns are apparently stable throughout life
Encoding & decision making are tractable
Image analysis & encoding time : 1sec
Search period : 100000 iris codes/sec
DISADVANTAGES OF IRIS SCANNING
Small target (1cm) to acquire from a distance (1m)
Located behind a curved, wet, reflecting surface
Obscured by eyelashes,lenses,reflections
Partially occluded by eyelids, often dropping
Illumination should not be visible or bright
CHARACTERICTICS FOR SELECTING
A BIOMETRIC TECHNOLOGY
Accuracy
Ease of use
Error incidence
Cost
User acceptance
Required security level
Long term stability
METHODS TO RATE BIOMETRICS
ACCURACY
FALSE- ACCEPTANCE RATE (FAR)
FALSE- REJECTION RATE (FRR)
The plot of FAR Vs FRR representing crossover error rate
COST ANALYSYS FOR BIOMETRICS
Hardware
Back-end processing power to maintain database
Research & testing of the system
User education
Exception processing
System maintenance
BIOMETRICS APPLICATIONS
Indian Initiatives
Bioenable Technology, Pune
Siemens Information System Ltd., Banglore
Axis Software, Pune
Jaypeetex ,Mumbai
Global Developments
Internet Security : Litronix, Usa
Windows Biometrics : Microsoft
Net Nanny Software International
Biometric Smart Cards : Polarid & Atmel
FUTURE OF BIOMETRICS
ATM Machine Use
Travel & Tourism
Public Identity Card
CONCLUSION
Your fingerprints, iris pattern, and voice will verify your identity
You can unlock your house or withdraw money from your bank with just a blink of eye, a tap of your finger,
or by just showing your face
