Facial recognition is a biometric software application that can identify a person through their digital image. The digital image here means the facial components of a person such as the size of the lips, the shape of the cheekbones, etc. They are mainly used for security reasons, but current trends indicate their application in multiple spheres such as online shopping, games, etc.

How does it work?

Facial recognition is based on the principle that different facial indicators are differentiated by the shape and size of the face. A facial recognition system identifies these differences as nodal points. Each human face has approximately 80 nodal points. These are measured in terms of:

Nose width
Lip size
Jaw line length
Depths of the eye socket
Distance between eyes
Cheekbones shape

The nodal points are then measured by creating a numerical code known as a Faceprint that represents the face in the database.

Some applications

Since the facial recognition system (FRS) is innovative and reliable, its use and applications are increasing with the support of government and private companies.

Financial security

Banks and financial institutions are using this technology to eliminate common PIN and password protection methods that could be forged. FRS can also protect vaults and deposit boxes from loot.


It helps to verify the identity of the buyers and streamlines the purchase and transaction process.


This serves as a bastion against international terrorists who want to unleash terror on foreign soil. The effectiveness of identifying a threat is multiplied by five, since it is difficult for human eyes to identify people with just a photograph.

Compliance with the law

An FRS application includes CABS’s acclaimed computerized child arrest, search and protection system. This is used globally to recover missing and exploited children. This helps verify abusers and traffickers.

Access control

FRS can help identify a person on their identity statements. Eliminate the risk of people getting fake passwords and access cards.

Scene surveillance / analysis

FRS has the ability to extract, categorize and search non-facial images such as scars, tattoos, marks, etc. The software is capable of identifying the exact people you want to find from the crowd. You can analyze archived video scenes for accurate faces.

Defense of the Fatherland

Defense of the homeland is an important part of the development of a country. Countries around the world are ensuring that this system helps them prevent terrorists from boarding airplanes, protecting critical infrastructure such as dams, temples, bridges, power plants, etc.

Aviation security

Airports are slowly moving towards this technology for obvious reasons. In addition to the usual metal detectors and fortifications, the use of FRS can help identify and catch suspects without much effort. Since most terrorists arrive via airplanes or ships, aviation becomes an important sphere to protect.

Verification of votes

Verify various government officials before voting and election campaigns. In addition, it stops the falsified and repeated voting.

Facial recognition is one of the most popular biometric technologies alongside iris and fingerprint scanning. However, FRS applications are on the rise and have made their way into the gaming industry as well. Due to the excellent features, your domain grows and will grow until this technology has not included each and every one of the necessary spheres.
