Forget passwords ...
Forget pin numbers ...
Forget all your security concerns ...
BIOMETRICSIntroductionGeneral systemFinger PrintIrisPerformance & ApplicationConclusion
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

BIOMETRIC SYSTEM
183.bin
The hardware captures the salient human characteristic
The software interprets the resulting data and determines acceptability.
HOW IT WORKS
FINGER PRINTOldest form of Biometrics
Highly Reliable
Uses distinctive features of fingers
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

Its the acquisition and recognition of a
persons fingerprint characteristics for identification purposes

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 PROPERTIESHigh degree of RandomnessNo two Iris are alikeStable in a persons lifeDoesn't vary with changes

BIOMETRIC PERFORMANCEFAR 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 PERFORMANCEFRR
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 PERFORMANCEFAR - As low as 1 in 1,000,00
FRR around 4%
IRIS PERFORMANCEFAR - As low as 1 in 1,000,000
FRR around 2%
