It
is not just necessity but it is must requirement. It doesn't need to say that
what I am talking about. I am talking about security. Today, attacks by
terrorism organization happen more often. Once you lost then no one would be
able to help, even police. But, according to me it is better to take prior
steps to prevent.
Today,
there are many security systems available in the market. They work on different
technologies. Take different factors in concern to authenticate the person. For
example, log cards require scanning barcode to give the access to any person
and biometric access control require scanning of real human features like
finger prints, eye retina, voice and face itself. Each has its own advantage
and disadvantage. According to these systems the cost varies as per the
security level they provide.
Biometric
access control is the new technology which depends on the factors like eye
retina, finger prints, voice and signature. So person who wants to access the
system require these factors as an authentication. Biometric access control
require scanner to scan real human features and convert it to digital format
which can be stored.
I
want to talk about Face recognition system and its advantages over others. It
is one type of system which is based on biometric technology. Face recognition
system scans whole face of the person. It includes shapes of face, stains on
face, distance between two eyes, distance between eye and nose, retina scan and
others. Let me explain the advantages of face recognition system in detail in
next paragraph.
Whole face, itself is an
advantage
In
movies, you might have seen that the thief makes lenses and passes it and
access the restricted thing or get entry in restricted region. By this example,
you might understand that only one parameter is not sufficient to give full
security. It is better that takes full face into scan and concern more than one
factor. Same is the case in finger print scan. It is possible to break the
security. Again Face recognition has added advantage.
Speed of scan
It
is really time consuming to scan the eye. Put your eye against the system. It
does require perfect placement of face. Suppose hundreds of persons
authenticate themselves takes a lot time. While face recognition system starts
scan from the front and until you reach near the gate system opens it for you.
In fact, today the systems can scan 100,000 faces per second. It is really good
at Door Access Control where thousands of people pass through every day.
Maintenance free system
Biometric
access control system is one time cost system. Once you have installed then
after you have to maintain a simple database. You can add or remove authorized
persons easily and without any cost. On other side, if you use identity card
then you have to issue identity card of every authorized person. It leads to
more cost. There is also a threat of lost of identity card.
Automatic Continuous
scanning
Let me explain, what is it? In other systems, once authenticated, the door stays open for some time. Through that time non restricted person can get entry. Suppose in finger print scanning system, once authorized person put finger door opens. After that two persons can get entry if they are quick. Same case is not possible in face recognition system. The whole door area stays under full security. If one has authenticated and opens the door, and a second person tries to enter without authentication the system detects it and alarms the threat. It means any person without authentication can't get entry. Follow us on Twitter
