characteristic
and
it
can caused
same
problem.
If
we
lost
our
card
and
it
is
taken
by
unauthorized person, that person can
learn
to copy the owner signature and they can use
that
card, as
long as
the card owner
is
not call
the bank to block the
use of
their credit
card.
To overcome this password and signature
method weaknesses then people try to develop
new
security
system in
order
to
protect
the
information
from unauthorized
person.
The
new
technology
that
developed
to
overcome
this
weakness is
called
as
Biometric
technology. This technology is used human
characteristic that taken to become a
password
for
verify the
user.
The biometric technology provide
two
functions, there are
verification and identification. The biometric technology can be divided into two classes,
there are behavioral and physiological.
The behavioral class related
to
people
behavior
which is contain signature and voice, so the signature and voice are used as a recognizer
of that person. The physiological class
more related to physical characteristic that owned
by the person, such as fingerprints, iris, retinal, DNA, face, etc. [30]
Besides using the biometric technology to get any information and data that we need, the
biometric technology can be
used
for attendance
system where
usually the company or
university
used
manual
system.
The
manual
system means
that
the
attendance
system
used
clock printed on the paper or
use personal signature. Using this system people can
easily do cheating like the signed the attendance for their friends who do not come
to
work or attend the class. The biometric technology can prevent cheating because it uses
the human uniqueness, such as
fingerprints, as the ‘signature’ so the other people cannot
sign in for their friends.
Nowadays
the
biometric
technology
is
already used
in
office,
school,
etc;
because
the
biometric technology
is
very safe and secure. Beside that the biometric technology
