Facial Recognition technology works on collating the facial biometric patterns of an individual’s face with a database of the known faces, to find the correct match.

Facial Recognition Technology: Functionality, Applications, & Significance in Today’s World

What Is Facial Recognition Technology?

Facial recognition technology is a rapidly advancing field in artificial intelligence. It works by capturing and analyzing unique facial features such as the distance between eyes, nose shape, and mouth structure to identify and verify individuals. This technology has a wide range of applications, from unlocking smartphones to enhancing security at airports and even tracking attendance in classrooms and workplaces. While it offers convenience and efficiency, it also raises important questions about privacy and data security, making it a topic of ongoing debate and regulation.

Describing how facial recognition technology works and discussing its significance in different sectors. Also explaining why there’s a sudden surge in the demand for facial-recognition technology-based attendance systems.

Due to technological advancements, the biometrics system has reached new heights. And with machine learning and AI-based programming, a new technology emerged that is widely known as ‘face recognition’ today.

From the education sector to law enforcement, the application of facial recognition technology has been diversifying every day, being used in various industries. Despite its universal adoption people often confuse facial recognition with face verification, which are two different things.

To understand facial recognition technology, we need to dig deep, and thoroughly look at its step by step process. And we’ll also talk about the significance and a large-scale demand for facial recognition-based attendance systems by numerous enterprises amid the phase of the novel coronavirus.


How Facial Recognition Technology Works?

Face recognition access control and attendance system has grown to be the most effective contactless biometric system in the world, due to the continual use of Machine Learning and AI (Artificial Intelligence).

It is associated with the face mapping of a human face. To put it simply, it is a biometric identification process to authenticate a person’s identity using their facial features. The camera captures the photo and records the video, and the internal program saves that information into a database.

Facial Recognition technology works on collating the facial biometric patterns of an individual’s face with a database of the known faces, to find the correct match. Steps that the facial recognition process includes are.

  • Detecting a Face.
  • Extracting its Facial Features.
  • Representing the Face &
  • Matching the Face.

Let’s take a look at each of these steps in detail.


1. Face Detection

Detecting a face of an individual is the initial stage of the face recognition process. It starts with a person’s face and facial patterns for identification. Generally, when we think of a human face, we think of their eyes, nose, eyebrows and mouth. In the same way, the facial recognition system needs to learn what a face is and how it looks like, first.

The detection process starts with the eyes, eyebrows, nose, etc. by calculating the width of the eyes, the distance between both eyes and nose, shape and size of the mouth, and so on. It is carried out with the help of neural networks and knowledge engineering algorithms on a large database of human faces looking at different angles and positions.

2. Extracting Facial Features

In the second step, the software learns to detect facial landmarks via computer vision algorithms. Facial landmarks are also known as nodal points and each human face has at least 80 nodal points. They are the keys to identifying faces saved into a large database.

Once the face is registered it can be adjusted in a position, size and a scale to match with the person’s face. It will help the software to accurately recognize it even if the user’s face moves or expressions change.

3. Facial Representation

After the facial features are extracted, and the facial landmarks, positions, size, scale, etc. are learned by the software, it creates a unique feature vector for every face in a numeric form. These vector codes are also known as faceprints, much like fingerprints in the biometric attendance systems. And after this step comes the last part of the process of face-matching.

4. Face Matching

It is the final step in the process. After completing the first three steps, the vector codes or the faceprints are compared with other facial codes in the database. The database has all the information of the users who already registered their faces. Face matching is done to check whether or not the face belongs to the same person.

Is Facial Recognition Technology Reliable?

The National Institute of Standard and Technology, or NIST, reported an issue regarding facial recognition technology back in December 2019. They performed research and found that facial recognition algorithms give demographic groups better results in spotting their representatives’ undetectable characteristics.

The facial recognition system can have almost perfect accuracy but not perfect. According to NIST’s facial recognition vendor test, the recognition technology uses verification algorithms to match any object to a precise reference image that can achieve 99.97% accuracy. These results are best in comparison to iris scanners.

Areas Leveraging Facial Recognition Technology

The adoption of facial recognition-based biometric attendance machine is growing rapidly amongst many industries. It is so because it provides people working in these sectors, a sense of security and privacy, however, some still argue in contrast with this idea. It is assisting them in solving their problems quickly and more efficiently.

Listed below are those sectors that adopted and relied upon facial recognition technology due to the worldwide spread of the coronavirus.

  1. Education Sector
  2. Media & Entertainment Sector
  3. Sector of Securtity & Surviellence
  4. Telecom & IT Sector
  5. Healthcare Sector
  6. Automobile & Transportation Sector
