Every person has a unique face. So, it can be used for security purposes. It is the best option as the face of a person can be captured from the distance, no need to interact with the person. It may be described as Biometric artificial intelligence which has the capability to recognize a human through its facial pattern analysis. Face recognition is very helpful these days.



Importance of face recognition

It helps in Laws to identify the criminal from devices during any police case. These day Law enforcement agencies are widely using this system, they collect mugshot for the criminals and compare them with the database at the village level, state level, and national level.

In some countries, Face recognition is also used to detect Fraud Voters or duplicate voting. Some organization also uses this technology to take attendance of the employees according to the stored database.


Demerits:- It has some demerits too. since it is a computer, don’t have its own brain. It can only work according to the feed data, there is a possibility of mistakes.  The facial recognition may misidentify the person.

How does Face Recognition Works

In humans, there are six areas in the brain’s temporary lobe known as “face patches”. Human brains have a neuron, which recognizes the faces and stores the data in memory. Facial recognition is just a software which recognizes the face, it is a biometric system that maps facial features from the photos or videos. Details like the distance between the eyes, the shape of the eye, the chin of a person’s face can be calculated with the help of facial recognition system which uses computer algorithms to get the facial features in the form of mathematical representation and stores the data as a faceprint. Then it is compared to the store data in the computer database. Some facial recognition system has also the tendency to calculate the percentage of the face matched with the given data.

Some practical application of facial recognition

Some apps use face recognition software to recognize the faces. These apps work by calculating the data with the help of face contours or nodal points. The nodal point is endpoints which are used to measure the variables in the face of a human. The biometric software identifies the 80 Nodal points on a human face, length, and breadth of the nose. The depth of the eyes and the shape of bones and many more. there are some apps by which supports face recognition software, they help you can get others app lock, you can also lock the home screen.

Face recognition in Facebook:-

Facial recognition software is also used by Facebook to tag peoples in photographic posts. After long research in the field of artificial intelligence, A Facial Recognition system has been developed known as “ Deep face”, which recognize the face in the photos posted on Facebook. Thus the data of the tagged person’s facial characteristics gets stored in the Facebook software. Again when you post the new photos of the same person, Facebook software may recognize him and suggest you.

Conclusion:- Facial recognition is really an amazing technology develops so far. Above you had noticed how it helps us in our day to day life. This area has been developing too much that now facial recognition software is also used in smartphones, for the screen lock. this helps us to keep our soft copy safe in the mobile and protect from the unknown source. These days it is being in use widely at different industries and technology. It is one of the technology spreading widely, as you can see today biometric system is also used for detecting the citizens of the country and also helps to purchase a sim card. Thus here, you can conclude that face recognition has made our life comfortable.
