Biometrics and Retina Scan Technology Lum OSMANI Alex CHERVENKOV Course: Information Security April 2008
Outline Biometrics Overview Biometrics Process Flow Retina Scan Technology Retina Scan and Security Applications Advantages and Disadvantages The Future of Retina Scan
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
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.
Greater degree of security over traditional authentication methods Accountability - who/when/what Fraud detection Convenience Cost savings/reduced risk of financial loss Why Biometrics?
Biometrics! How it works?
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
Retina Scan and Security! Accurate biometric technology Retina - unique to the individual, very difficult to spoof False Acceptance Rate (FAR) - less then % False Rejection Rate (FRR) - 10%
Applications! Logging into the computer system Physical Access Systems Bank vaults, server rooms, control tower Military installations, power plants, high-end security applications
Advantages... High accuracy Sample usability Fraud resistance Small template size
Disadvantages... Hard to use, high-skill requirement Hard to enroll Consumer perception about the eye itself Intrusive technology High cost
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
