easy to be used, so many company or school start to implement this technology in their
system. The
biometric technology might be
needed now since the use of password or
signature
is
not
safe
anymore.
When
we
using
password
there
is
possibility
that
we
forgot or
lost
it and also
if
we use signature there
is possibility that someone copy
it and
use
it, but
if we
use
the biometric technology
we cannot be
forget
it or copied by other
person. Nowadays the biometric technology is safer than using the password in order to
be recognized by
the system if the
user
is authorized to
use
the
information or
not. The
most
common
used
biometric
technology
now
is
fingerprint
where the
scanner
or
the
hardware to read the fingerprint pattern already sale in the market.
Although
use
people
physical
or
behavior
as the
recognizer,
but
it already
proved
that
people
do
not
need
worry
if
their
physiological change. For example the use of
fingerprints, people must know that their fingerprint might be change when they get
older,
but
when
they
stop
growing
then
the
shape
of their
fingerprint
will
be
the
same.
Beside that
it already proven
that the
uses of
hardware of
fingerprint scan,
iris
scan, or
retinal scan are safe; and even for the retinal and iris scan they already create a hardware
that
use
some
kind
of
infrared that
the
amount
of
light
is still
same
like
people
walk
around on the sunny day. [31]
1.2 Scope
There are several of human characteristic that implemented in biometric technology such
as fingerprints, retina, iris, face recognition, and DNA; beside that there are common
biometric that
used
in
many
university, which
is signature.
To prevent the
thesis become
so
general
then
this
thesis
will
be
limited
only
to
describe
more
deeply
about
one
