Biometric Face Scanner: Advantages and Disadvantages in the Digital Age

Biometric face scanner recognizes and confirms a consumer’s identity using their face. It can instantly identify users in photos and videos. Moreover, facial recognition is a kind of biometric security, and other essential forms include fingerprint, retina, eye, or iris recognition. Law enforcement and security also use this technology. Hence, in 2022, the face recognition software market was projected at $5 billion. Now, by 2032, it’s reaching $19.3 billion. Therefore, facial scanners and AI recognize users by scanning their facial expressions. 

The Advantages And Disadvantages Of Biometric Face Recognition

In everyday life, the surging use of facial recognition technology raises awareness among the masses. No doubt, there has been support and backlash for the system. Therefore, to understand the situation, let’s know the advantages and disadvantages of face recognition. 


1. Improved Security

The accuracy and convenience provided by facial recognition technology to secure boundaries and reduce illegal activities. 

2. Investigate Crimes  

From police to law enforcement, this is a valuable tool to inspect unwarranted and illegal activities.

3. Effortless Integration

The advanced facial recognition solution in the marketplace incorporates security systems. 

4. Convenience and Usability 

The software provides the comfort to skin thousands of faces in seconds. Thus, the complete process makes face identification better. 

5. Better Accuracy

With the passage of time, facial recognition technology has evolved, providing a better accuracy rate than ever before. 


1. Privacy Breach

The most debatable topic in the business world is the breach of privacy that face recognition has improved with time. The advanced technology used to arrest the general public and criminals without consent raises concerns. 

2. Data Storage 

The AI usage in Facial recognition makes provisions for a vast database. The advanced technology depends on machine learning to train themselves so that enough learning can improve accuracy. 

3. Error and bias

Few researchers have negative impressions of face recognition technology, which has a high error rate among demographic groups. 

Face Recognition Scanner Working

Clients are familiar with these services to open phone locks. Facial recognition does not rely on a picture database to determine an applicant’s identity. It verifies an individual as the technology owner but restricts access to others. 

Besides opening the phone locks, the biometric face scanner contrasts the individual’s face via camera to the user’s pictures in a database. The checklist has everyone’s picture, including users who aren’t involved in any kind of criminal activity. The user image can be gathered from anywhere, such as social media accounts. 60% of US adults say it’s acceptable for law enforcement agents to use biometric facial recognition services to decrease security threats. 

Let’s understand how facial scanner operates: 

1. Face Detection 

The mobile camera can now inspect and identify a face picture in a crowd. The image actually depicts the person looking directly or in any other way. 

2. Face Analysis

The second step is the software capturing and analyzing the applicant’s face. Usually, facial recognition scanner depends upon 2D rather than 3D pictures, as they quickly resemble 2D images with current images or those in databases. Moreover, the software also scans the individual’s facial features, such as space from forehead to chin, ear, chin or lips contour, distance between eyes, and eye sockets deepness. The primary purpose is to identify the facial features that distinguish between the genuine user’s face. 

3. Transform the Picture into Data 

The face recognition services change analog information with a digital one relying upon the individual’s facial expressions. The software automatically twists the face analysis into a geometrical formula, and the numerical code is called faceprint. Moreover,  the thumbprints are unique and used for recognition purposes.  

4. Discover a Match

Biometric face scanner compare standard databases with others. The FBI accesses 650 million images from various databases. 

Facial Recognition Significance

Fingerprint algorithms have to be more effective than facial recognition. Hence, the face recognition efficiency can be estimated in two ways: 

  1. False positivity
  2. False negativity

False negativity refers to the software’s failure to investigate the same user. False positivity occurs when the system mistakenly considers two different user’s images to be the same individual. Moreover, there is a tradeoff between these two; occasionally, placing the threshold is problematic. 

Key Takeaways

Facial recognition verification mainly uses AI, suggesting passwords can be stolen but not face print. Therefore, it is more secure than identification and authentication systems. Facial recognition accuracy differs due to outer characteristics such as background, gender, environment, lighting, age, hair, and liveness. Additionally, the facial recognition scanner application is diverse and used by governments, public bodies, and financial institutions. 

Undoubtedly, The face scan identity plays a vital role in society’s future. The customer should use advanced technology to provide authentic, desired, and secure results. Moreover, the numerous benefits of this process can’t be overlooked. This advanced technology lets users make accurate decisions about their fate.
