BIOMETRICS
BIOMETRICS
Forget passwords ...
Forget pin numbers ...
Forget all your security concerns ...
WHAT IS BIOMETRICS?
Automated method
Pattern recognition system
Specific physiological or behavioral characteristics
WHY USE IT?
Traditional methods involving passwords and PIN numbers
Biometrics highest level of security
CHARACTERISTICS USED
• Fingerprints
• Voiceprints
• Facial features
• Writing patterns
• Iris patterns
• Hand geometry
BIOMETRIC SYSTEM
Data Collection
Transmission
Signal Processing
Data Storage
Decision
BIOMETRIC SYSTEM
The hardware captures the salient human characteristic
The software interprets the resulting data and determines acceptability.
FINGER PRINT
Oldest form of Biometrics
Highly Reliable
Uses distinctive features of fingers
FINGER PRINT RECOGNITION
Global features
Local features
STAGES
Fingerprint Scanning
Fingerprint Matching
Identification
IMAGE CAPTURE
Optical
Thermal
Capacitance
Ultra Sound
IMAGE ACQUISITON
BRIDGE CODE
SPUR CODE
PROCESS
IRIS RECOGNITION
Pattern recognition technique
Identification by mathematical analysis of the random patterns.
Based upon the qualities of the Iris
Iris is a protected internal organ whose random texture is stable throughout life
IRIS PROPERTIES
High degree of Randomness
No two Iris are alike
Stable in a persons life
Doesn't vary with changes
IRIS SCAN
Camera at close proximity
Captures photograph
Uses Infra red light to illuminate
High resolution photograph
IRIS SCAN IMAGE
IRIS CODE
Localization of inner and outer boundaries
Pattern of 512 bytes
Complete and Compact description
More complete than features of DNA
IRIS SYTEM
IRIS RECOGNITION
Database of millions of records
Iris code generated is compared
Searching algorithm based on Properties of Iris
Order of a few seconds
AVIATION – IRIS DEVICES
BIOMETRIC PERFORMANCE
FAR
The FAR is the chance that someone other than you is granted access to your account.
Low false acceptance rate is most important when security is the priority
FRR
The FRR is the probability that are not authenticated to access your account.
A low FRR is required when convenience is the important factor
FINGERPRINT PERFORMANCE
FAR - As low as 1 in 1,000,00
FRR –around 4%
IRIS PERFORMANCE
FAR - As low as 1 in 1,000,000
FRR –around 2%
APPLICATIONS
Criminal identification
Prison security
ATM
Aviation security
Border crossing controls
Database access
