2
BIOMETRICS Forget passwords... Forget pin numbers... Forget all your security concerns...
3
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 Fingerprints Voiceprints Voiceprints Facial features Facial features Writing patterns Writing patterns Iris patterns Iris patterns Hand geometry Hand geometry
7
BIOMETRIC SYSTEM Data Collection Transmission Signal Processing Data Storage Decision
8
BIOMETRIC SYSTEM
10
The hardware captures the salient human characteristic The software interprets the resulting data and determines acceptability. HOW IT WORKS HOW IT WORKS
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
Pattern Area Core Point Delta Line types Ridge Count Ridge Patterns GLOBAL FEATURES

IRIS RECOGNITION Pattern recognition technique Pattern recognition technique Identification by mathematical analysis of the random patterns. Identification by mathematical analysis of the random patterns. Based upon the qualities of the Iris Based upon the qualities of the Iris
31
Iris is a protected internal organ whose random texture is stable throughout life 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
36
IRIS SYTEM Pre processing Feature- extraction Identification Verification Stored templates Uniform distribution Reject Accept Iris scan image capture Iris localization Iris code comparison
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. 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 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. The FRR is the probability that are not authenticated to access your account. A low FRR is required when convenience is the important factor 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
