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.
So, as I have stated that security is the area where cost is not important. One time cost can hesitate to you but I am sure you will get the reward for sure. My suggestion is, always go for biometric access control and in particular face recognition system. I hope after reading my article you have got clear picture in your mind.
