1. Biometrics and Retina Scan Technology Lum OSMANI Alex CHERVENKOV Course: Information Security April 2008

2. Outline Biometrics Overview Biometrics Process Flow Retina Scan Technology Retina Scan and Security Applications Advantages and Disadvantages The Future of Retina Scan

3. Biometrics Overview (1) “Something you know” - PIN / passwords “Something you have” - smart cards, security cards, ATM cards Biometrics - automated use of behavioral/physiological characteristics to determine/verify identity “Who you are” - fingerprints, eyes, faces and “What you do” - speaking, writing

4. Biometrics Overview (2) Recognition by face is the oldest form of identification method. Due to technological advancement biometrics system has become available over the last few decades. The word biometrics comes from two Greek terms “bios” for life and “metros” for measure.

5. Greater degree of security over traditional authentication methods Accountability - who/when/what Fraud detection Convenience Cost savings/reduced risk of financial loss Why Biometrics?

6. Biometrics! How it works?

7. Retina Scan Technology! “Enroll” = personal information + retina scan “Feature Extraction” + conversion to unique 96 bytes templates “Second time” = current template compared with the enrollment template

8. Retina Scan and Security! Accurate biometric technology Retina - unique to the individual, very difficult to spoof False Acceptance Rate (FAR) - less then 0.0001% False Rejection Rate (FRR) - 10%

9. Applications! Logging into the computer system Physical Access Systems Bank vaults, server rooms, control tower Military installations, power plants, high-end security applications

10. Advantages... High accuracy Sample usability Fraud resistance Small template size

11. Disadvantages... Hard to use, high-skill requirement Hard to enroll Consumer perception about the eye itself Intrusive technology High cost

12. The Future of Retina Scan!? The most accurate and reliable biometric technology Located in high security areas It still remains an intrusive technology Hard to get the user acceptance
