BIOMETRICS
  • Forget passwords ...
  • Forget pin numbers ...
  • Forget all your security concerns ...

BIOMETRICS
  • Introduction
  • General system
  • Finger Print
  • Iris
  • Performance Application
  • Conclusion

4
WHAT IS BIOMETRICS?
  • Automated method
  • Pattern recognition system
  • Specific physiological or behavioral
    characteristics

5
WHY USE IT?
  • Traditional methods involving passwords and PIN
    numbers
  • Biometrics highest level of security

6
CHARACTERISTICS USED
  • Fingerprints
  • Voiceprints
  • Facial features
  • Writing patterns
  • Iris patterns
  • Hand geometry

7
BIOMETRIC SYSTEM
  • Data Collection
  • Transmission
  • Signal Processing
  • Data Storage
  • Decision

HOW IT WORKS
  • The hardware captures the salient human
    characteristic
  • The software interprets the resulting data and
    determines acceptability.

11
FINGER PRINT
  • Oldest form of Biometrics
  • Highly Reliable
  • Uses distinctive features of fingers

12
FINGERPRINT
  • Finger-scan biometrics is based on the
    distinctive characteristics of the human
    fingerprint
  • A fingerprint image is read from a capture device
  • Features are extracted from the image
  • A template is created for comparison

13
FINGER PRINT RECOGNITION
  • Global features
  • Local features

14
GLOBAL FEATURES
  • Pattern Area
  • Core Point
  • Delta
  • Line types
  • Ridge Count
  • Ridge Patterns

BASIC RIDGE PATTERNS
  • Loop
  • Arch
  • Whorl

LOOP, ARCH AND WHORL
18
STAGES
  • Fingerprint Scanning
  • Fingerprint Matching
  • Identification

19
FINGERPRINT SCANNING
  • Its the acquisition and recognition of a
  • persons fingerprint characteristics for
  • identification purposes

IMAGE CAPTURE
  • Optical
  • Thermal
  • Capacitance
  • Ultra Sound

IRIS RECOGINITION
30
IRIS RECOGNITION
  • Pattern recognition technique
  • Identification by mathematical analysis of
    the random patterns.
  • Based upon the qualities of the Iris

31
  • Iris is a protected internal organ whose
    random texture is stable throughout life

32
IRIS PROPERTIES
  • High degree of Randomness
  • No two Iris are alike
  • Stable in a persons life
  • Doesn't vary with changes

33
IRIS SCAN
  • Camera at close proximity
  • Captures photograph
  • Uses Infra red light to illuminate
  • High resolution photograph

34
IRIS SCAN IMAGE
35
IRIS CODE
  • Localization of inner and outer boundaries
  • Pattern of 512 bytes
  • Complete and Compact description
  • More complete than features of DNA

37
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
  • 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

40
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

41
FINGERPRINT PERFORMANCE
  • FAR - As low as 1 in 1,000,00
  • FRR around 4

42
IRIS PERFORMANCE
  • FAR - As low as 1 in 1,000,000
  • FRR around 2

43
APPLICATIONS
  • Criminal identification
  • Prison security
  • ATM
  • Aviation security
  • Border crossing controls
  • Database access

44
SOME BIOMETRICS STILL IN DEVELOPMENT
  • Scent
  • Ear Shape
  • Finger nail bed
  • Facial 3D
