What is Facial Recognition? Where We Can Use It?

The biometrics required to log in to mobile devices may be the first thing that springs to mind when thinking of facial recognition technology. It has, however, been present since the 1800s and is used for a variety of purposes, including access control and security. Facial recognition has come a long way in the last decade. It has developed massively in many fields like Construction, Banking, Airport security, and Phone unlocking.

What is Facial Recognition?

Facial recognition is a biometric method that uses modern technology to match a digital face to a real face. It works by measuring the distance between various characteristics on a person’s face, such as the distance between the nose and the lips. The information is then compared to known faces in a database to find an exact match.

This system can be used in the Following Fields:

Airports Security:

Face recognition technology has been installed in airports since 2011 to improve security and safety for passengers and employees. Since then, it’s become more widely used at large and busy airports, and because it’s so accurate, there’s less chance of travelers misrepresenting their identities. Passengers’ passports are scanned at electronic gates and compared to a picture captured by a camera to ensure that they match; if they don’t, the traveler will be denied boarding.


Biometric technology was first used in banking in 2015. Facial recognition is being used to connect to banking apps without using a username or password. This aids in the secure storage of a person’s personal information as well as the safe verification of their identification. It increases efficiency and saves time, especially when used to make purchases in a store.

Facial recognition technology has evolved substantially over the last decade, and using it in a variety of settings has helped to increase safety and efficiency. In the years ahead, the system will only improve and be used in more places.

Super Markets:

Facial recognition has grown in popularity in retail during the previous decade. By reducing theft and creating a safer shopping experience, this technology aids in the prevention of product loss in stores. The mere sight of a camera is enough to dissuade someone from stealing. When someone steals from a store, it’s often because they’ve done it before; face recognition software makes it easy to recognize these people and watch them as they enter the store.

Phone unlocking:

Phones and social media are two of the most significant changes in the use of facial recognition. Facebook began using this technology to identify persons in photos published to the site in 2010. Every day, millions of images are posted, and Facebook can recommend tagging people based on face recognition in its database. Furthermore, the facial unlocking feature was first offered on the Android 4 in 2011, but it did not take off at the time since it stored a face as a 2D image, which was insecure.
