BIOMETRICS • Forget passwords ... • Forget pin numbers ... • Forget all your security concerns ...
BIOMETRICS • Introduction • General system • Finger Print • Iris • Performance & Application • Conclusion
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
HOW IT WORKS • 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
GLOBAL FEATURES • Pattern Area • Core Point • Delta • Line types • Ridge Count • Ridge Patterns
BASIC RIDGE PATTERNS • Loop • Arch • Whorl
STAGES • Fingerprint Scanning • Fingerprint Matching • Identification
FINGERPRINT SCANNING • It’s the acquisition and recognition of a person’s fingerprint characteristics for identification purposes
IMAGE CAPTURE • Optical • Thermal • Capacitance • Ultra Sound
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
High degree of Randomness No two Iris are alike Stable in a persons life Doesn't vary with changes IRIS PROPERTIES
IRIS SCAN • Camera at close proximity • Captures photograph • Uses Infra red light to illuminate • High resolution photograph
IRIS CODE • Localization of inner and outer boundaries • Pattern of 512 bytes • Complete and Compact description • More complete than features of DNA
IRIS SYTEM Uniform distribution Stored templates Reject Pre processing Feature-extraction Identification Verification Accept Iris scan image capture Iris localization Iris code comparison
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
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 • 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
SOME BIOMETRICS STILL IN DEVELOPMENT • Scent • Ear Shape • Finger nail bed • Facial 3D
