Facial biometrics: Fast, convenient and reliable identification
Facial recognition biometrics has expanded across various sectors, establishing itself as an innovative tool for identifying and authenticating individuals by providing fast and non-intrusive solutions.
In previous articles, we explored fingerprint biometrics (Fingerprint biometrics: The oldest form of biometric identification) and iris recognition biometrics (Iris recognition: Accuracy and security in biometric identification). Now, it is time to take a closer look at the biometric technology with the widest use of applications: facial recognition biometrics.
Facial recognition biometrics has established itself as an innovative and effective technology in the field of personal identification and authentication. This technique uses unique features of the human face, allowing not only identity verification, but also the analysis of demographic characteristics such as age and gender. As digitalization advances, facial recognition has found applications in various sectors, from public security to customer service.
This technology is distinguished by its ability to operate in real time and without physical contact, making it particularly attractive in a world where security and convenience are paramount. In addition, its resistance to variables such as changes in lighting or facial expressions makes it a reliable option for everyday applications.
The use of facial biometrics is not a recent concept. Although biometric identification has its roots in older methods, such as the use of fingerprints, facial recognition has evolved since the first attempts at image analysis in the 20th century.
As digital technology advanced and processing power increased, more sophisticated systems were developed in the 1980s and 1990s. These systems began to employ facial image databases, although their application was limited and often inefficient. It was not until the 21st century, with the rise of artificial intelligence and machine learning, that facial recognition became a widely used tool.
Facial biometrics are currently used in a variety of contexts to provide personalized and secure experiences for users. From unlocking smartphones to surveillance systems in public spaces, their presence is becoming more and more common.
The COVID-19 pandemic accelerated its adoption, as contactless solutions became essential. Government and private organizations have implemented this technology to control access and ensure security in different environments, reflecting a trend towards digitalization and modernization of security systems.
The facial recognition process relies on several key components that ensure its effectiveness. First, the hardware plays a crucial role, as it includes high-resolution cameras and lighting systems designed to capture facial images in various conditions. Captures can be made using a conventional camera or a smartphone camera, either as a static portrait or as part of a video while the subject is in motion. The quality of these images is critical to the success of the recognition.
Once the image is obtained, it is processed to create a facial template, which is a mathematical representation of the face based on unique characteristics, such as the distance between the eyes and the shape of the nose, allowing specific details of the face to be captured in an easily comparable format. The resulting template facilitates facial recognition and database searching, allowing the system to operate efficiently.
Facial recognition can be performed using two types of matching: one-to-one (1:1) and one-to-many (1:N). In the 1:1 process, identity is authenticated by comparing facial images, which can be done manually by a human evaluator or in an automated manner. In the latter case, if the system generates an appropriate similarity score, actions such as opening doors or authorizing transactions can be allowed. In contrast, the 1:N approach compares an image to a database of multiple faces, allowing for a less intrusive capture than other biometric methods.

Advantages and disadvantages of this biometric technology
Facial recognition has established itself as one of the most versatile biometric technologies. Its use in different sectors has revealed multiple advantages that go beyond its basic functionality. Below are the main advantages of this technology.
- Contactless: Unlike fingerprint-based biometrics, facial recognition doesn´t require physical interaction, making it a more hygienic and convenient option. This feature eliminates concerns about cleaning and maintenance of contact sensors.
- Surveillance applications: This technology is especially valuable in public environments for security, as it can identify people in crowds without them knowing. This makes monitoring at mass events or public spaces easier without disrupting the normal flow of activities.
- Advances in AI: Recent developments in artificial intelligence have increased the accuracy and speed of facial recognition, enabling faster and more reliable identification, even in difficult lighting conditions or when the subject is moving.
- Speed and efficiency: Identification can be carried out in real time, allowing for a quick response in critical situations.
- Non-Intrusive: By not requiring physical contact, the user experience is improved and security is increased.
- Scalability: It can be deployed in a wide variety of environments, from personal devices to massive security systems.
However, despite its advantages, facial biometrics also presents some challenges or disadvantages, such as:
- Privacy concerns: The collection and storage of facial data can lead to privacy risks and ethical dilemmas due to the capture of images without consent.
- False positives and negatives: Despite technological advances, errors in identification can occur, resulting in false positives and false negatives.
- Dependence on image quality: Factors such as lighting and facial position affect, although now to a lesser extent, the accuracy of recognition, making identification difficult in certain conditions.
- Accuracy issues: The effectiveness of facial recognition can be compromised by facial features and external conditions, such as the presence of accessories or masks.
In which sectors is it advisable to implement facial biometrics?
Facial recognition biometrics is a versatile technology that can be adapted to various sectors. In the field of criminalistics, it is used to identify suspects from security recordings. In government, its implementation is common in border controls and in the issuance of identity documents. In prisons, this technology helps to monitor and control access to penitentiary facilities. Companies also benefit from its use in access control systems and to improve workplace safety. In the banking sector, it facilitates secure transactions and customer identification. In addition, in educational centers, it improves security by controlling access to the facilities. Finally, in the pharmaceutical industry, it can be used in environments where employees do not cover their faces, ensuring authentication in critical processes.
Facial recognition biometrics represents a significant advance in identification and authentication, offering fast and secure solutions. As it continues to evolve, this technology opens up new opportunities in an interconnected world.
