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
![Page 6: BIOMETRICS](https://reader036.fdocuments.net/reader036/viewer/2022083004/56813069550346895d96465f/html5/thumbnails/6.jpg)
Present – Measuring Humans
• Fingerprint Identification
• Hand Geometry
• Speaker Recognition
• Face Location
• Multibiometrics
![Page 7: BIOMETRICS](https://reader036.fdocuments.net/reader036/viewer/2022083004/56813069550346895d96465f/html5/thumbnails/7.jpg)
How It Works ?
• A Pattern Recognition System
• Mathematics is Everywhere
• Vector Data Storage
• Verifying the Physical Characteristics
• Verifying the Behavioral Characteristics
![Page 8: BIOMETRICS](https://reader036.fdocuments.net/reader036/viewer/2022083004/56813069550346895d96465f/html5/thumbnails/8.jpg)
Fingerprint Identification
![Page 9: BIOMETRICS](https://reader036.fdocuments.net/reader036/viewer/2022083004/56813069550346895d96465f/html5/thumbnails/9.jpg)
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
![Page 11: BIOMETRICS](https://reader036.fdocuments.net/reader036/viewer/2022083004/56813069550346895d96465f/html5/thumbnails/11.jpg)
Speaker Recognition
• Faster Then Previous Methods
• Less Secure
• Cost for Basic Infrastructure is Much Higher

Face Location Beginning of A New Era
![Page 13: BIOMETRICS](https://reader036.fdocuments.net/reader036/viewer/2022083004/56813069550346895d96465f/html5/thumbnails/13.jpg)
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
![Page 14: BIOMETRICS](https://reader036.fdocuments.net/reader036/viewer/2022083004/56813069550346895d96465f/html5/thumbnails/14.jpg)
• Higher Accuracy Rate
• Higher Security
• Very Reliable Due to Retinal & Iris Tests
• Verification Time is Low

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
![Page 19: BIOMETRICS](https://reader036.fdocuments.net/reader036/viewer/2022083004/56813069550346895d96465f/html5/thumbnails/19.jpg)
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
