Identity theft is a significant issue in many industries, leading to substantial financial losses each year. The Federal Trade Commission (FTC), consumers reported a loss of over $10 billion to fraud in 2023, with identity theft being a primary reason for this deficit. This represents a 14% increase from the previous year, emphasizing the increasing threat of identity theft and fraud.

Thus, biometric facial recognition technology is necessary for industries that have undergone a remarkable transformation since the start of the technology. These solutions have become essential to modern security and identification processes to dissuade identity theft.

This blog will explore the history and development of facial recognition technology with highlighting the role of artificial intelligence and machine learning in enhancing its accuracy and preventing identity forgery.

How Facial Recognition Solution Came into the Beginning?

The development of facial recognition technology began in the 1960s when Woodrow Bledsoe created a system to manually record facial feature coordinates on a grid. This early method laid the foundation for automated systems, although it was labor-intensive and lacked precision in matching faces. In the 1970s, researchers built upon Bledsoe’s work by using 21 specific facial markers, such as the distance between the eyes and the width of the nose, to automate the recognition process.

The beginning of digital technology in the 1990s was drawn to a significant turning point for facial recognition solutions. However, the advancements in computer processing power and digital cameras enabled the development of more sophisticated algorithms. In 1991, due to computational constraints,  facial recognition was employed in security systems and criminal databases on a limited scale.

The Function of AI and Machine Learning in the Face Recognition Process

In the 2000s, there was an unrecognized and rapid shift from 2D to 3D facial recognition. The 3D systems capture the shape of the face using sensors that provide a more accurate representation than 2D images. It also reduces the impact of lighting and angle variations. However, the high-resolution cameras and improved sensor technology further enhanced the precision of these systems in determining the image or real-time person. 

AI-based intelligent algorithms and deep learning have changed the overall dynamics of the face recognition process. It is known that the traditional methods relied on predefined algorithms and feature extraction approaches, which limited the system’s ability to adapt to new data. With AI and ML, systems can now learn and improve over time. By training neural networks on extensive datasets, these systems can automatically identify and extract relevant features without human intervention.

Face Recognition Deep Learning In Different Industries 

Deep learning has enabled the development of highly accurate facial recognition systems. These systems are developed to automatically learn spatial patterns of features from input images with adaptive concentrations. As a result, they can recognize intricate patterns and details in faces that traditional algorithms may overlook. The industries that use biometric facial recognition technology are; 

  • Security and Surveillance Providers
  • Banking and Financial Institutions 
  • Educational Industries 
  • Healthcare Sector 
  • Retail Outlets and  Factories 
  • Transportation and Travel
  • Public Safety
  • Hospitality industry 
  • Entertainment and Events
  • Real Estate

Integration with Biometric Face Recognition

Facial recognition technology (FRT) has become a critical component of biometric systems, which use biological data to identify individuals. Unlike fingerprint or iris recognition, facial recognition is non-intrusive and can be performed from a distance without physical contact. Thus, FRT is now considered the most optimized and efficient technology consistently providing accurate results. 

Biometric face recognition technology has been widely adopted across various sectors. For instance, it speeds up and secures passenger processing in airports and border control. Financial institutions utilize it to maintain security in online transactions and mobile banking. Nowadays, smartphones commonly feature facial recognition for user authentication, which offers a convenient and secure alternative to traditional passwords and PINs.

Ethical and Privacy Considerations AI Face Recognition Online

Ethical and privacy concerns have emerged as biometric facial recognition technology becomes more prevalent online. The prospect of administration mishandling and unauthorized subjective data collection are consequential issues. For instance, European regulatory frameworks like the General Data Protection Regulation (GDPR) aim to address these concerns by implementing strict data usage and consent guidelines. Developers and organizations must prioritize transparency and ethical considerations when deploying biometric facial recognition technologies.


The evolution of biometric facial recognition technology from its early manual methods to today’s cultivated systems is evidence of technological progress. With deep learning and AI integration, facial recognition has acquired remarkable accuracy and efficiency. This technology is considered to be the most reliable when it comes to verifying faces and identify individuals on the basis of their data registered. However, as the world advances, it must counteract technological innovation by considering ethical factors and protecting privacy to ensure the responsible use of powerful technology.
