BIOMETRICS

SCOPE Biometrics – Still an Evolving Technology Biometrics – Past and Present How It Works? Machines for Bio Measurements Future Aspects Benefits of Adopting Biometric Techniques Will Biometrics Solve All My Security Concerns ?

Evolving Technology A Technology – Still Under Major Changes A Technology – Still Changing its Confined Area A Technology – Still Under Controversies A Technology – Which Would be Remembered as a Part of Bio Informatics

Past – In the Early 20 th Century Testing Cereals in Agricultural Field In Experimental Human Trial Clinics In Environmental Studies To Analyze Human Diseases

Present – You Are the Key! Automatic Identification Solving Security Concerns No Need for Passwords

Present – Measuring Humans Fingerprint Identification Hand Geometry Speaker Recognition Face Location Multibiometrics

How It Works ? A Pattern Recognition System Mathematics is Everywhere Vector Data Storage Verifying the Physical Characteristics Verifying the Behavioral Characteristics

Fingerprint Identification

Fingerprint Classification Categories – whorl, right loop, left loop, arch and tented arch Four Directions – 0, 45, 90 and 135 degrees FingerCode is Generated K – Nearest Neighbur Matching

Hand Geometry More Secured Due to More Ridges Less Reliable on User Side Time Constraint is there

Speaker Recognition Faster Then Previous Methods Less Secure Cost for Basic Infrastructure is Much Higher

Face Location Beginning of A New Era

Face Recognition & Detection Vector Data Generated from Ridges Color, Position, Scale and Rotation Recorded Various Poses & Expressions Recorded In Verification, Algorithm Regenerates eye, mouth and boundary maps

Higher Accuracy Rate Higher Security Very Reliable Due to Retinal & Iris Tests Verification Time is Low

Machines & Equipments Panasonic CCDs Panasonic Authenticam (Iridian Technologies) Identix Biotouch DigitalPersona Fingerprint Sensor

Machines & Equipments Veridicom Fingerprint Sensor Digital Biometrics Fingerprint Sensor Siemens ID Mouse Pulnix HandGrabber

Future Aspects Replacing Security Cameras by Face Recognition Systems Modifying Multibiometrics Techniques

Benefits of Adopting Biometrics No Need to Remember Passwords Unauthorized Access to Personal Data Can be Prevented Fraudulent Use of ATMs, Credit Cards Can be Prevented No Need to Token Based Systems

Will Biometric Solve All Security Concerns? No System Can be 100% Safe Biometric Measures Can be Very Successful in Fighting Today's Security Concerns Major Drawback in Adopting Biometric Systems is that Concerned Person Need to be Physically Present
