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
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
