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 20th 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
