Since the advent of artificial intelligence, identification technologies are in full development. Facial recognition is one of those systems that allow a complete and precise identification of a person through a simple photo or video. Its impact on the contemporary world is considerable and it offers infinite possibilities to improve our lives. In this article, we will see what facial recognition is and the remarkable advances that this innovation provides.

What is facial recognition?

Facial recognition is an artificial intelligence (AI) technology that can recognize a face from an image or video. Computers use sophisticated algorithms to analyze the physical characteristics of the face such as the shape of the nose, the size of the eyes, the distance between the eyes, etc. After analyzing these characteristics, the computer can then compare the face to an existing database and identify the corresponding person.

How does facial recognition work?

Before understanding how facial recognition works, it is important to understand the different steps involved in the process. This process consists of the following steps:

  • Image Capture: When facial recognition is enabled, an image or video is captured.
  • Analysis: Once the image or video is captured, it is sent to a special algorithm that analyzes the physical characteristics of the face.
  • Matching: The facial characteristics are then compared to those in an existing database to find a match.
  • Authentication: Once a match is found, the person is authenticated.

Applications of facial recognition

Facial recognition is used in a wide variety of fields such as security, mobile device access, payment systems, online banking, etc. Let’s look at some of the main applications of this technology.


Facial recognition is widely used in the security field because of its ability to detect intruders and potential threats. It can be integrated into surveillance systems to automatically monitor authorized and unauthorized individuals. In addition, it can also be used to protect sensitive sites and public places.

Access to mobile devices

Facial recognition can be used to unlock mobile devices to protect their data from theft and fraud. This is a faster and more convenient method of authentication than using a password or fingerprint lock.

Payment systems

Facial recognition can also be used to facilitate online transactions. With this technology, customers can make payments without having to remember their credit card information or bank account number. All it takes is one photo to complete a transaction.

Online Banking

Banks can use facial recognition to provide secure access to customer accounts. This allows customers to perform online banking transactions such as transferring money, checking balances, etc. without having to enter their login or confidential information.

Benefits of facial recognition

There are many advantages to using facial recognition as an identification technology. Some of the main benefits are as follows:

  • Faster and more convenient: Facial recognition is faster and more convenient than other identification methods such as PIN codes or fingerprints. A photo or video is all that is needed to make the identification.
  • More secure: Facial recognition is a very secure technology and can be updated regularly to keep up with the latest technological advances. In addition, it is less susceptible to human error and hacking attempts.
  • Less expensive: Facial recognition is less expensive than other identification methods because it requires less hardware. In addition, it is easy to implement and manage.

Disadvantages of facial recognition

Despite its many advantages, facial recognition also has some disadvantages:

  • Vulnerable to fake images: Facial recognition can be vulnerable to the use of fake profiles or altered photos. Therefore, it is important to have an advanced security system to minimize this kind of risk.
  • Privacy Issues: Most facial recognition systems store a person’s information, which can compromise privacy. It is therefore important to be careful about how this information is used.
  • Algorithmic racism: Some algorithms may discriminate or favor certain groups racially. It is therefore important to ensure that the algorithms are properly designed to not take into account a person’s race when identifying them.


In conclusion, facial recognition is a very promising technology with many possibilities. It is widely used in many areas such as security, online banking, mobile device access and payment systems. While it offers significant advantages, it also has some disadvantages that should be considered.
