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
