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, gaming, etc.
How does it work?
Facial recognition works on the principle that different facial pointers 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
jawline length
eye socket depths
distance between eyes
cheekbone 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 the usual PIN and password protection methods that could be spoofed. FRS can also safeguard vaults and deposit boxes against loot.
electronic commerce
It helps verify the identity of buyers and streamlines the purchase and transaction process.
Immigration
This serves as a bastion against international terrorists who want to unleash terror on foreign soil. The effectiveness to identify a threat is multiplied by five, since it is difficult for human eyes to identify people with only a photograph.
law enforcement
An FRS application includes the acclaimed CABS computerized arrest, record system and child protection measures. 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 your identity claims. Eliminate the risk of people obtaining false keys and access cards.
Scene monitoring/analysis
FRS has the ability to extract, categorize and search for non-facial images such as scars, tattoos, marks, etc. The software is able to identify the exact people you want to find in a crowd. You can analyze scenes from archived videos for the accurate faces.
homeland defense
Homeland defense is an important part of a country’s development. Countries around the world ensure that this system helps them prevent terrorists from boarding planes, protecting critical infrastructure such as dams, temples, bridges, power plants, etc.
AviationSecurity
Airports are slowly leaning 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 a lot of work. Since most terrorists arrive via aircraft or ships, aviation becomes an important area to protect.
Vote Verification
Verify various government officials prior to voting and election campaigns. Also, stop falsified and repeated voting.
Facial recognition is one of the most popular biometric technologies along with iris and fingerprint scanning. However, FRS applications are on the rise and have also made their way into the gaming industry. Due to the excellent features, its domain grows and will grow until this technology has not included each and every necessary sphere.
