2. BIOMETRICS


Unique measurable characteristics of a human being that
can be used to automatically recognize an individual or
verify an individual identity.
Used for security authentication.

3. FINGER VEIN
AUTHENTICATION
TECHNOLOGY
 A promising biometric
pattern for personal
identification in terms
of its security and
convenience.
 Uses
DSP platform.
 Takes
only about 0.8
seconds to verify one
input finger- vein
sample.

4. VEIN RECOGNITION
A system for
Identification using
a person’s unique
vein patterns.
 Veins as a
biometrics tool
involve the
measurement of
the blood vessels
on the back of
your palm or a
single finger of
hand.

11. EXPERIMENTAL RESULTS
DATA SET:
 100 subjects (55% male and 45%female)
 Images from the forefinger, middle
finger, and ring finger.

12. PERFORMANCE EVALUATION

Two types of errors
FALSE
REJECTION
RATE(FRR)
• which claims a
genuine pair as
impostor
FALSE
ACCEPTANCE
RATE(FAR)
• which claims an
impostor pair as
genuine
FRR
FAR
EER
