What is Facial Recognition Used For?

As society grows, the need for better security grows, too. Facial recognition technology has become widely used throughout the world to make life safer, faster, and more comfortable. Unlike traditional identification systems such as password, email verification, fingerprint, and selfies, biometric facial recognition has become one of the safest and most successful. We'll go through the main three areas of face recognition in-depth in this article after explaining what face recognition is and how it works.

What is Facial Recognition?

Face recognition is a technology that collects and recognizes human faces. The unique facial biometrics like the eyes, nose, and mouth from a photo is used to map and detect the face. It creates a pattern of facial features that it uses to identify or group a face and compares the information with a database of known faces for a match. Additional functions such as face identification, grouping, and verification can all be supported by facial recognition technology.

How Does Face Recognition Work?

Facial recognition technology respectively detects, analyzes, and confirms the identification of a face in a photo or a video using biometric algorithms. Thanks to artificial intelligence and machine learning, face recognition systems can function with the highest levels of safety. An algorithm that learns what a face starts the detecting phase of facial recognition. The algorithm is usually trained with images of faces by the program's developer. The variety of photographs given into the system has a significant impact on the accuracy of the system throughout the analysis and identification stages. Because the database is hosted on servers and cannot be found on the capture equipment, this biometric facial recognition technology requires an internet connection.

Although each face recognition system, which typically depends on proprietary algorithms, works in a somewhat different way, the process can be broken down into three steps:

  1. The technique of detecting a face in an input image is known as detection. As a result, each face is enclosed within a frame. The facial recognition algorithms are initially trained to understand what a face appears like on numerous data entries to finish this step.
  2. The second phase is analysis, which involves mapping out each face's traits. This is accomplished by determining the distance between the eyes, nose, and mouth, as well as the chin's shape. These measurements are then mixed and transformed into a unique set of integers known as a faceprint.
  3. The phrase "recognition" refers to the process of identifying a person in an image. This level is sometimes replaced by categorization in other applications. In such circumstances, the algorithms do not validate a person's identification but rather classify them into one of many groupings, such as gender or age.

3 Main Areas of Facial Recognition

While face recognition was first created for security concerns, it has now expanded to incorporate a wide range of applications. Face recognition is now used in almost every part of our lives, even without us realizing it. Face recognition is primarily used by many people to unlock their phones. The way governments and corporations exploit this technology, on the other hand, has a significant influence on humankind.


Facial recognition is also gaining traction in the retail industry as a tool to improve the customer experience both in-store and online. Customers' retail experiences can be enhanced thanks to this advanced technology. For instance, if the retail industry knows who visits the store and their purchasing pattern, the business can change their offers on the go to better meet the customer's demands, and they can have better relations with them. Kiosks at stores, for instance, can recognize consumers, offer product recommendations based on their purchase history, and send them to the appropriate product. With "face pay" technology, customers can escape huge queues at checkout and pay in a slower way.

Facial recognition is also used to help provide individualized customer experiences by speeding up fraud and theft investigations. Face recognition is used to rapidly detect known shoplifters, organized retail criminals, and people with a history of fraud when they visit retail businesses. Loss prevention and retail security specialists can be quickly warned when a consumer enters a store, preventing a threat by matching their photographs against massive databases of offenders. Retail crime has already been dramatically reduced by face recognition technologies.


Another advantage of facial recognition is biometric internet banking. Customer verification methods are only natural in a world where financial services have almost fully gone digital. Customers can authorize transactions by simply smiling at their smartphones or computers rather than utilizing one-time passwords. Using face recognition, there are no passwords for hackers to steal. If hackers get access to your photo database, a technique for evaluating whether the source of a biometric sample is a real person or a fictitious representation should prevent them from impersonating you. Additionally, criminals now often utilize skimming devices to get access to ATMs.Facial recognition might eventually take the place of plastic cards and PINs as a more secure way to avoid fraud.

Digital and Physical Security

Face recognition's consumer acceptability is increasing its use in public safety and security. This technology has the potential to be a valuable instrument in the fight against crime, such as detecting wanted criminals among crowds, identifying offenders whose photos have been caught on a surveillance feed, or arresting terrorists as they enter your nation. Face recognition technology is already being implemented at airports; for example, several airports utilize face scanning to verify visitors' IDs at customs. Face recognition is currently used to unlock a range of phones, including the latest iPhone. This technology is a great approach to securing personal data and ensuring that sensitive data is unavailable to the offender if a phone is stolen.


Face recognition software powered by artificial intelligence can assist in detecting suspicious activity, tracking down known offenders, and assuring crowd safety. Furthermore, face recognition technology improves the ease and security of everyday activities such as banking, digital security, and shopping. It can make the entry of businesses more secure, assist in avoiding all sorts of fraud, and make utilizing internet services safer.
