template from
the digitized
blood vessel
pattern, after

-
The
blood
vessel
pattern
is
unique
for each
individual,
and even
identical
twins
have
quite
different
patterns.
It is
postulated
that the
no two
vessel-patterns
are the
same,
similar
to that
of iris.
-
The
pattern
of the
blood
vessels
are
individual-specific
and do
not
change
with
aging or
surface
effects.
-
Psychological
burden
is less
than
other
biometrics
technology.
-
Difficult
to
counterfeit.
-
Easy to
use as
only a
single
finger
is
inserted
into the
reader
for
certification.
