Modern Security System - Face Recognition System

With the escalating crime rates, it is quite uneasy to rely solely on the protection of the law. The numbers of terror attacks, across the world, have increased the significance of having a security system in place. It isn't just the law enforcement government agencies or big corporate houses which need to be on the guards when it comes to using modern security systems but it has also become a ought to-have for small commercial houses and for residences too. Because when it comes to a well-organized terror attack, the terrorists leave
no stone unturned in finding a place where they are able to plant a bomb, or for that matter hide their weapons for a large scale terror attack. Hence, this makes it imperative for residents also to install a home security system in their abode and produce an aura of peace.

We are living in an era where problematic intruders are getting armed with more and more bold technology. But the advancement of technology is an incessant process. As we plunge into the times where the camouflage, which the burglars use, can no longer escape the eyes of wide-awake modern security system, there's no reason why we cannot live with unruffled minds.

Biometrics is a form of access control. it's a method, which is used for recognizing humans based on one or more intrinsic physical or behavioural traits. It may also be used to establish the identity of individuals in groups that are under surveillance.

The two main classes of biometric characteristics are mentioned as follows:

1. Behavioural: As the name suggests, they're related to the behaviour of a person. for example, an individual's typing rhythm, gait and voice.

2. Physiological: they're related to the shape and structure of the body. Examples are face recognition, fingerprint, DNA, hand and palm geometry and body odour.

What's a Face Recognition System?

Face recognition system is among the physiological biometrics, which is used as among the another and mass security measure. it is a computer program or an application which identifies a person from a digital image or a video frame from a source.

How it works?

The ability to differentiate between the background and the face is of high significance in a facial recognition system as this enables the system to identify a face inside a crowd. Every face has numerous and distinguishable landmarks, the different peaks and valleys that add to the facial features. The person's facial features are equated, by the system, with those of the one stored in the database. The system makes use of the eighty nodes or nodal points, comprising the face print. These nodal points are measured creating a numerical code that represents the face in the database. Some of them measured by the system are as follows:

1. Depth of the eye sockets

2. Width of the nose

3. Distance between the eyes

4. The length of the jaw line

5. The shape of the cheekbones

Face recognition system is now compatible with cameras and is in use in airports just like banks. The incredible potential which a modern facial recognition system possesses does not deter the manufacturers from striving to enhance the usability and accuracy of the systems.
