[Guide] Facial Recognition Technology for Access Control Systems

2022/12/16

Access control systems are used to identify individuals and grant entrance to specific locations, such as warehouses, factories, or offices. These systems are often powered by edge devices, which have seen great leaps in processing power in recent years, making them ideal for modern facial recognition access control usage. With the help of this technology, the newest generation time clocks now perform even quicker than before and also use high-powered cameras that allow employees to use facial recognition to check in/out without swiping a badge, entering a PIN, or scanning fingerprints. In this article, we share key considerations for adopting facial recognition in access control systems and will guide you through choosing a solution that best fits your needs.

What is facial recognition access control?

Facial recognition access control systems leverage the speed and accuracy of biometrically verified identity checks to determine who can enter premises (or at least some part of the premises) or who can access lockers or operate specialized equipment. This access control technology relies on comparing the unique characteristics of the human face for identity verification. Beneath the surface, the technology uses artificial intelligence and deep learning to work with great speed and accuracy. With many parts of a business becoming increasingly automated, it is natural to extend the efficiency automation delivers to access control.

How does facial recognition access control work?

Access control covers a spectrum of security use cases such as physical access, health monitoring, on-site safety, and tracking who is still inside during an emergency.

Access control systems follow three main steps to protect the physical security of a facility or a restricted area from unauthorized access.

access steps

Step 1. Identification

The first step for facial recognition access control is to identify the presence of an individual. Proper implementation of an access control system makes it possible to determine the identity of any person who enters a building or accesses secure or restricted areas. It can also monitor the movement of individuals throughout an organization’s facilities.

Step 2. Authentication

Once the access control system identifies the presence of an individual, it must authenticate the person’s identity. Two-factor authentication (2FA) is the simplest, most effective way to ensure users are who they say they are.

Step 3. Authorization

After an individual’s identity is successfully authenticated, access control systems will grant access to the facility or restricted area(s) based on predefined criteria.

What are the benefits of facial recognition access control systems?

Traditional access control systems mainly use key cards or PINs to identify users and grant access, but these methods carry risks, such as the possibility of a stolen key card or leaked PIN. In recent years, biometric technologies such as fingerprints, iris recognition, and facial recognition have become mainstream in modern visitor management and access control systems. However, using fingerprints or iris recognition increases visitor surface contact. Facial recognition requires no personal contact, making it ideal for building a touchless access control system, thus maintaining workplace health and safety.

Using facial recognition technology for access control offers several key benefits:

1. User convenience

Your face is your ID! The most noteworthy benefit is convenience: indivduals no longer need to carry a key card or remember a PIN.

2. Better security and fewer risks

Facial recognition prevents unauthorized access. Lost or stolen keys, or sharing of PINs, is no longer a risk.

3. Contactless access

Compared to cards, PINs, fingerprints, or even iris scanning, facial recognition is an ideal solution for building a touchless access control system, even on occasions when mask-wearing is required.

What devices are used for facial recognition access?

access different device

You may be surprised at the wide range of devices that can be used for facial recognition-based access systems. Systems can scale from a humble smart device, like a spare smartphone or tablet, through low-power edge and AIoT devices, reaching up to modern laptops, industrial PCs and kiosks, all the way up to GPU-accelerated servers with large arrays of 2D and 3D connected cameras.

Your chosen solution will probably be based on the scale of your business and the number of people who will be passing through the access area(s) day to day. A small business with just a handful of employees could rely on relatively lower-end repurposed smart devices – all that is needed at the low-end is a device that has a built-in camera that can connect to the internet to open a web browser interface. On the other hand, for larger businesses wishing to implement AI-based facial recognition access control at entrances or exits that are extremely busy, faster GPU-accelerated hardware with high-quality 2D and/or 3D cameras with good lighting would be preferable.

FaceMe is a cross-platform solution, which gives users a wide range of choices of device operating systems including Windows, Linux, Android, and iOS.

What Facial Recognition Features Are Essential for Access Control?

access features

Although facial recognition technology has many helpful features, several features stand out as essential to successfully integrating facial recognition in access control systems. Luckily, they are all available for customers who choose to use FaceMe®.

1. Outstanding Accuracy

Top-quality facial recognition relies on accuracy. People must be identified and verified correctly. FaceMe’s facial recognition engine is among the most accurate in the industry, with 99.81% accuracy in NIST FRVT 1:1 and 1:N.

2. Mask Support

Personnel often wear masks for health, safety, or hygienic reasons. Therefore, successful access control systems need to implement high-accuracy facial recognition technology for employees wearing masks. Fortunately, FaceMe provides over 98.21% accuracy, even when individuals don’t remove their masks or other protective gear.

3. Spoofing Prevention/Liveness Detection

Liveness detection, often referred to as anti-spoofing, is a critical feature in any facial recognition system that is designed to secure restricted items, such as medicine cabinets. Without liveness detection, unauthorized individuals may be able to trick facial recognition access control systems by using photos or videos of authorized individuals, thereby gaining access to secure areas. Liveness detection needs to be certified by a third-party to ensure impartiality. FaceMe’s anti-spoofing detects impersonation and substitution attempts and is certified by iBeta, an internationally recognized, independent, third-party testing and quality assurance organization.

4. Cross-Platform Optimization

In developing access control systems, companies implement native, hybrid, and cross-platform approaches. Integrating facial recognition requires a reliable solution compatible with various platforms. FaceMe is a cross-platform facial recognition engine ideal for custom scenarios and uses cases where customers need to mold algorithms to their infrastructure. It is optimized for various hardware configurations, from high-end workstations to low-power chipsets typically used in IoT devices, and is compatible with Windows, Linux, Android, and iOS operating systems.

The concept of identity is a cornerstone of security, and facial recognition systems can verify a person’s identity quickly and accurately. Day to day, most facial recognition security systems in businesses will see an individual approach an access gate, confirm that they are a genuine employee, and let them pass unhindered. Other security examples that benefit from these systems include airport gates, police surveillance activity, and banking ATMs. Facial recognition is even used on a smaller scale, particularly with smart devices (like an iPhone) and all the personal data it holds.
Depending on the industry, the application of facial recognition technology might be rather differently targeted.
