Biometrics and Retina Scan Technology
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.
Why Biometrics?
Greater degree of security over traditional authentication methods
Accountability - who/when/what
Fraud detection
Convenience
Cost savings/reduced risk of financial loss
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 0.0001%
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
