What is Facial Recognition?
Just like all the Biometric Verification technologies, facial recognition technology is another key technology for identifying humans with their faces. It uses a camera or a face scanner hardware with an application software to scan faces. Then, the data from the hardware is used to match with the existing database to confirm the identity of the user. Artificial Intelligence highly influences this process as pattern matching across thousands of face data is a time-consuming procedure. With new datasets and toolkits software enterprises are making it possible to make it a reality. This is exactly how you unlock your iPhone in just mere seconds or even less.
The process of facial recognition consists of different steps in place to maximize the use of face scanners and identify people. Before diving right into the intricacies let’s head into the past to understand the need for face recognition technology.
A Dive into the History of Face Recognition
We humans identify each other with different aspects such as facial looks, voice, and appearance. With the advent of technology, computers are now efficient enough to identify humans with facial features, and it’s possible due to research made in the early 1960s! While the concept of facial recognition dates further back to the 1850s, the landmark research was led by Woodrow W Bledsoe’s team in 1964. This enabled computers to recognize images and subjects using programming principles. Here is a complete timeline of facial recognition technology to date.
- 1850s: The use of photographing systems to understand photographs in the English prisons to identify prisoners across different police stations.
- 1860s: Print of first photograph to put reward posters with people’s facial features.
- 1920s: Detective agencies using photographs to analyse the facial features to identify people and catch the assaulters.

- 2024: The facial recognition technology is currently one of the highly employed systems for identity verification across diverse industries.
How Does Facial Recognition Technology Work?
Just like any other biometric verification system, facial recognition technology also measures some key aspects of the human face. These measurements can be the position of your eyes, depth of your jaws, lips, nose width and the list goes on. These characteristics of the human face are combined with specialized algorithms that give numerical values using mathematical calculations. In computer terms, all facial traits are called Nodes that vary from person to person.
Nodes Connection
The facial recognition system calculates the distance between each node to make a connection with each other. Each calculated value is converted into a dataset. With the help of machine learning modules and efficient algorithms, the system automatically compares the dataset with a large pool of other node calculations. If any exact match is found, the system alerts the software to output a successful recognition message. Although the process is not this simple, the main workflow is similar across all major Facial Recognition Software solutions. Here is the step-by-step workflow of the process.
- The dataset is unique for every face pattern which allows the system to filter out the Search Facial Recognition.
- With large amounts of data sets already present in the system, the software solution performs various checks to ensure the accuracy of the result after filtering a specific dataset.
- These checks include twin detection using AI intelligence and relative marking.
- New solutions also incorporate liveness detection features to make systems Fraud Detection. Liveness detection asks the person in front to perform certain movements for a more deep face scan. This prevents users from accessing personal profiles with face masks or images to trick the system.
How do Tech Giants use facial recognition technology?
Almost all tech giants, even Google is testing facial recognition technology for their enterprise solutions. In recent years, we have seen devices get Face Recognition Features with the existing hardware such as front-cameras. However, the upcoming years promise a more Secure Identity as companies are now working on more sophisticated hardware that focuses solely on facial recognition technology. Here is how tech giants are moving forward, combining the power of AI with image processing.
Microsoft
Microsoft is the leader when it comes to enterprise solutions and it is one of the several corporations that are working to enhance facial recognition systems. It is testing the technology with more details of the human face such as skin tones. Also, new Algorithms Microsoft is in works with will make it one of the pivotal players in improving facial recognition technology across various industrial levels. One such example is their ongoing face recognition projects that are evaluated by NIST (National Institute of Standards and Technology)
Google is also not static in this department. It powers a deep neural network measuring system that is working on detecting even micro expressions from human faces. The Google Cloud Face Detection API is one such example that uses optical flow to intelligently map out facial expressions. This is much faster and more accurate than traditional face scanning systems. The solution also works in real-time video establishing a sequence of expressions recorded on each face.
Apple
Apple already is well-known for its FaceID scanning from its iPads. It uses a neural engine to perform an in-depth face scan and define a mathematical representation of the user’s data. Apple is always a market leader in the smartphone industry and is working on improving facial recognition technology with various hardware and software advancements. This is why we can now unlock our latest mobile devices from Apple with a mask on or even in dark environments.
