What is facial recognition? Where can we use it?

The biometrics needed to log into mobile devices may be the first thing that comes to mind when you think of facial recognition technology. However, it has been around 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 tremendously in many fields such as 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 with a real face. It works by measuring the distance between various features on a person’s face, such as the distance between the nose and lips. The information is then compared to familiar faces in a database to find an exact match.

This system can be used in the following fields:

Airports Security:

Facial recognition technology has been installed at airports since 2011 to improve security and safety for passengers and employees. Since then, it’s been increasingly used at large and busy airports, and because it’s so accurate, travelers are less likely to misrepresent their identities. Passenger passports are scanned at electronic gates and compared with a photo taken by a camera to ensure they match; if they don’t, the traveler will be refused entry to the aircraft.


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

Facial recognition technology has evolved significantly over the past decade and its use in different environments has contributed to greater security and efficiency. The system will only get better in the coming years and will be applied in more places.


Facial recognition has grown in popularity in retail over the past decade. By reducing theft and creating a safer shopping experience, this technology helps prevent product loss in stores. Just seeing a camera is enough to deter someone from stealing. When someone steals from a store, it’s often because they’ve done it before; facial recognition software makes it easy to recognize these people and view them as they enter the store.

Unlock phone:

Phones and social media are two of the major changes in facial recognition use. Facebook started using this technology in 2010 to identify individuals in photos published on the site. Millions of images are posted every day and Facebook may recommend tagging people based on facial recognition in its database. In addition, the face unlock feature was first offered on Android 4 in 2011, but it didn’t launch then because it saved a face as a 2D image, which was unsafe.
