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
