BIOMETRICS
  • Introduction
  • General system
  • Finger Print
  • Iris
  • Performance & Application
  • Conclusion
what is biometrics
WHAT IS BIOMETRICS?
  • Automated method
  • Pattern recognition system
  • Specific physiological or behavioral characteristics
why use it
WHY USE IT?
  • Traditional methods involving passwords and PIN numbers
  • Biometrics highest level of security
characteristics used
CHARACTERISTICS USED
  • Fingerprints
  • Voiceprints
  • Facial features
  • Writing patterns
  • Iris patterns
  • Hand geometry
biometric system
BIOMETRIC SYSTEM
  • Data Collection
  • Transmission
  • Signal Processing
  • Data Storage
  • Decision
slide10

HOW IT WORKS

  • The hardware captures the salient human characteristic
  • The software interprets the resulting data and determines acceptability.
finger print
FINGER PRINT
  • Oldest form of Biometrics
  • Highly Reliable
  • Uses distinctive features of fingers
finger print recognition
FINGER PRINT RECOGNITION
  • Global features
  • Local features
slide13

GLOBAL FEATURES

  • Pattern Area
  • Core Point
  • Delta
  • Line types
  • Ridge Count
  • Ridge Patterns
slide15

BASIC RIDGE PATTERNS

  • Loop
  • Arch
  • Whorl
stages
STAGES
  • Fingerprint Scanning
  • Fingerprint Matching
  • Identification
slide18

FINGERPRINT SCANNING

  • It’s the acquisition and recognition of a

person’s fingerprint characteristics for

identification purposes

image capture
IMAGE CAPTURE
  • Optical
  • Thermal
  • Capacitance
  • Ultra Sound
iris recognition
IRIS RECOGNITION

Pattern recognition technique

Identification by mathematical analysis of the random patterns.

Based upon the qualities of the Iris

slide30
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 PROPERTIES
iris scan
IRIS SCAN
  • Camera at close proximity
  • Captures photograph
  • Uses Infra red light to illuminate
  • High resolution photograph
iris code
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 SYTEM

Uniform distribution

Stored templates

Reject

Pre processing

Feature-extraction

Identification Verification

Iris scan image capture

Iris localization

Iris code

comparison

iris recognition1
IRIS RECOGNITION
  • Database of millions of records
  • Iris code generated is compared
  • Searching algorithm based on Properties of Iris
  • Order of a few seconds
biometric performance
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

biometric performance1
BIOMETRIC PERFORMANCE

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
FINGERPRINT PERFORMANCE
  • FAR - As low as 1 in 1,000,00
  • FRR –around 4%
iris performance
IRIS PERFORMANCE
  • FAR - As low as 1 in 1,000,000
  • FRR –around 2%
applications
APPLICATIONS
  • Criminal identification
  • Prison security
  • ATM
  • Aviation security
  • Border crossing controls
  • Database access

SOME BIOMETRICS STILL IN DEVELOPMENT

  • Scent
  • Ear Shape
  • Finger nail bed
  • Facial 3D
