Everything we do online requires a form or identity verification. Typically, we use usernames and passwords. But that’s changing. The sensitive nature of today’s transactions calls for a more sophisticated and secure approach, and facial recognition is growing in adoption.
What is Facial Recognition?
Facial recognition technology or FRT is a type of biometric security technology that uses an individual’s facial features to perform identification and authentication.
It relies on computer vision algorithms to analyze and interpret unique facial characteristics, such as the arrangement of facial landmarks and features. FRT can confirm identity through different mediums, including photos, videos, or real-time scenarios.
How Facial Recognition works
Facial recognition begins with the capture of facial characteristics. Facial mapping is performed by measuring nodal points on the face to create a unique facial signature for each individual.
This is where biometric verification services/software that use computer vision algorithms analyze and interpret unique facial characteristics.
A face captured can then be added to a database for identification and authentication when a user requesting access to a system that uses FRT for access control initiates the recognition process. The system takes a snapshot of the user and compares captured facial data against a database of known faces to establish a match.
Advantages of Using Facial Recognition Systems
Facial recognition systems are versatile enough to be applied in various scenarios, and here’s why:
- Enhanced Security and Safety: FRT enhances security measures, providing efficient and accurate identification.
- Fraud Prevention: FRT helps fight fraud by verifying individuals’ identities, particularly in financial transactions and access control scenarios.
- Convenience and Efficiency: FRT is a quick and efficient verification system, surpassing other biometric technologies like fingerprints in terms of speed and convenience.

- Ethical Issues: FRT can contribute to racial discrimination in law enforcement and create ethical dilemmas related to testing inaccuracies and racial bias.
- Limited Accuracy: The technology is only sometimes 100% accurate, leading to limited reliability in identifying individuals and can produce errors in certain situations.
Many businesses from different industries share standard security requirements that FRT can address. Here’s a look at use cases in other markets:
FRT is a secure access control method, allowing or denying entry based on verified identities. It has become a crucial business component, preventing unauthorized access to sensitive areas or systems.
FRT verifies user identities to help reduce the risk of fraudulent activities. It is a preventative solution to unauthorized access to systems and databases that store sensitive information.
Airport and Border Control
Airlines use FRT for automated check-in and boarding processes, streamlining passenger flow and reducing queues.
Banking and Finance
Banks utilize FRT alongside iris and fingerprint scanning to enhance user verification. It also bolsters fraud detection and prevention and streamlines Know Your Customer (KYC) processes.
Healthcare facilities use FRT for secure access control. It enables authorized personnel to enter restricted areas, safeguarding sensitive information and resources.
FRT in smartphones works by capturing images, analyzing them to detect the user’s face, and automatically granting access to the device if a match is found.
Finding Missing Persons
FRT makes tracking and identifying individuals easier, a crucial capability when searching for missing persons in large crowds.
Tracking Student or Worker Attendance
Automated attendance systems with FRT allow students or workers to mark their attendance by facing a camera. It eliminates manual tracking, saving time and improving efficiency.
Is Facial Recognition accurate?
FRT accuracy can vary based on several factors, including the algorithms used, the quality of images, and deployment conditions. Here are key considerations that influence the accuracy of a solution:
- Algorithm Quality: Deep learning and artificial intelligence have significantly improved FRT accuracy. But as with all solutions, the effectiveness of a system depends on the specific algorithm implemented. Poorly designed algorithms trained on limited data are less likely to be as accurate as sophisticated solutions.
- Image Quality: High-quality images contribute to better accuracy, but lighting, angles, and resolution impact the system’s ability to identify faces correctly. Poor-quality images may also result in a lower accuracy rate.
- Diversity of Faces: Biases may arise if the dataset is representative of a small group of facial types, leading to potential inaccuracies, especially for specific demographic groups.
- Real-world Conditions: Deployment conditions, such as environmental factors and camera positioning, play a role in accuracy. FRT may be harder to achieve in crowded or poorly lit environments.
Is It Safe?
While a powerful solution for highly accurate identification and authentication, FRT and how it functions raises the following concerns:
FRT involves capturing and processing individuals’ facial features, raising privacy concerns. Unauthorized or intrusive use may violate personal privacy rights. As such, privacy advocates have called for robust regulations and ethical guidelines that protect individuals’ right to privacy.
Potential Data Risks
The storage and management of FRT data pose security risks if not adequately protected. Centralized databases pose the biggest threat, offering a single point of attack for bad actors. Sensitive information in centralized databases is vulnerable to breaches, potentially leading to identity theft or misuse.
Biases and Inaccuracies
FRT systems may exhibit biases, especially if the training data is not diverse. Inaccuracies, particularly in identifying individuals from certain demographic groups, raise ethical concerns and the potential for unjust consequences.
Legal and Regulatory Landscape
The legal and regulatory landscape for FRT varies globally. Some regions have implemented restrictions to safeguard privacy, while others have embraced the technology with fewer constraints. For FRT’s effective integration and use, legal frameworks must evolve and standardize, especially where intercountry collaboration is required to combat fraud-related crimes.
Public Perception and Trust
Public perception and trust play a vital role in accepting FRT technology. Given the issues around privacy, addressing concerns through transparent policies, informed consent, and responsible practices is essential to build and maintain trust among users and the broader community.
Other Types of Biometric Identification Technology
FRT is often paired with various technologies, including AI, as a form of biometric identification to catch deep fakes. Other biometric technologies include:
Fingerprint biometric technology is a method of identifying and verifying individuals based on the unique patterns present in their fingerprints.
It identifies distinct ridges, valleys, and minutiae points on an individual’s fingertips for identification purposes. It is also commonly used on smartphones as a liveness detection means of authentication.
Signature recognition analyzes and verifies an individual’s signature for authentication purposes. Signatures display unique characteristics and patterns, allowing for distinctive biometric identifiers.
It is possible to compare these features to a stored template for verification by capturing and digitizing a signature and extracting relevant features.
