How Do Biometric Access Control Systems Work?
A biometric access control system utilizes an individual’s unique physical characteristics or measurements for identification purposes. These specifications are known as biometric traits or biometric information. Among the biometric traits are fingerprints, facial characteristics, iris patterns, voice types, or palm veins.
Biometric access control systems utilize different devices and technologies to capture, store, and compare these biometric features. Let’s summarize the entire process this way:
Capturing the biometric data
The first step is presenting the biometric feature of interest. This could be your fingerprint, your face, your eye, or even your voice. Just place it on or near a biometric device, like a scanner or a camera, and let it do its magic. The device will capture your biometric data and turn it into a bunch of numbers and letters.
Storing the biometric template
Next, the device will take your biometric data and make it even more secure. It will encrypt it into a biometric template. The biometric template will capture the unique patterns of your biometric feature. The device will then store this template in a safe place, either locally or on a server somewhere else.
Comparing the biometric features
Now comes the fun part. Whenever you want to access something that requires biometrics, you just need to show your biometric feature again. The device will capture your biometric data and compare it with the biometric template. If they match, you’re in! The device will recognize you and give you access. If they don’t match, the device will reject you and keep you out.
Now that you know the basics of biometrics, let’s dive deeper into some of the different types of biometric technologies and devices and how they work.
Fingerprint Recognition
Fingerprint recognition is one of the oldest and most widely used biometric technologies. It is based on the fact that every person has unique characteristics on their fingertips, which can be used to verify their person’s identity. Fingerprint recognition uses a device called a fingerprint scanner, which is an optical sensor that captures the image of the fingerprint and converts it into a digital format. The fingerprint scanner then extracts the features of the fingerprint, such as the minutiae points, which are the points where the ridges end or bifurcate. The fingerprint scanner then creates a stored template, which is a mathematical code that represents the unique pattern of the fingerprint. The stored template is stored in a secure database and compared with the fingerprint data of the intended user when physical access is requested.
Fingerprint recognition is a fast and easy way of biometric authentication, as it only requires the user to place their finger on the fingerprint scanner. It is also a cost-effective and reliable biometric system, as fingerprint scanners are relatively cheap and durable, and fingerprints are stable and consistent over time. However, fingerprint recognition also has some limitations, such as the possibility of fingerprint damage, distortion, or spoofing, which may affect the accuracy and security of the system. Moreover, fingerprint recognition may not be suitable for some individual users who have dry, wet, or dirty fingers, or who have skin conditions that affect their fingerprints.
Facial Recognition
Facial recognition is another popular and widely used biometric security technology. Only identical twins can spoof this method of biometric access control, and even that depends on the sophistication level of the system. Aside, every other person has a unique set of facial features, such as the shape, size, and position of the eyes, nose, mouth, chin, and ears, which can be used to identify them. Facial recognition uses a device called a facial recognition camera, which is a digital camera that captures the image of the face and converts it into a digital format. The facial recognition camera then analyzes the facial features of the image, such as the distance between the eyes, the width of the nose, or the angle of the jaw. The facial recognition camera then creates a facial template, which is a mathematical code that represents the unique features of the face. The facial template is stored in a secure area and compared with the facial data of the user when access is requested.
Facial recognition is a convenient and user-friendly way of biometric authentication, as it only requires the user to look at the facial recognition camera. It is also a versatile and adaptable biometric technology, as facial recognition cameras can work in different lighting and environmental conditions, and can also recognize faces from different angles and poses. However, facial recognition also has some challenges, such as the possibility of facial changes, variations, or disguises, which may affect the accuracy and security of the system. Moreover, facial recognition may raise some privacy and ethical concerns, as facial images may contain sensitive and personal information about the users, such as their age, gender, race, or emotion. Therefore, facial recognition should comply with privacy regulations and provide an extra layer of security for the users.
Iris Recognition
Iris recognition is one of the most accurate and secure biometric technologies. Every person has a unique pattern of colors and textures on their iris (the colored ring around the pupil of the eye) which can be used to identify them. Iris Recognition uses a device called an iris scanner, which is a specialized camera that captures the image of the iris using infrared light and converts it into a digital format. The iris scanner then extracts the features of the iris, such as the rings, furrows, or freckles. The iris scanner then creates an iris template, which is a mathematical code that represents the unique pattern of the iris. The iris template is stored in a secure database and compared with the iris data of the user when access is requested.
Iris recognition is a highly secure and accurate way of biometric authentication, as it has a very low false acceptance rate and a very high false rejection rate. It is also a non-invasive and contactless biometric technology, as it does not require the user to touch or interact with the iris scanner. However, iris recognition also has some drawbacks, such as the high cost and complexity of the iris scanners, and the sensitivity of the iris to light and eye conditions, which may affect the quality and availability of the iris images. Therefore, iris recognition is often used in combination with other biometric security systems, such as fingerprint scanning or face recognition, to provide a comprehensive security solution for different levels of security and identity verification.
Voice Recognition
Voice recognition is another common and widely used biometric technology. It is based on the fact that every person has a unique voice, which is influenced by the shape and size of their vocal cords, mouth, nose, and other factors, which can be used to identify them. Voice recognition uses a device called a voice recognition system, which is a microphone that captures the sound of the voice and converts it into a digital format. The voice recognition system then analyzes the voice features of the sound, such as the pitch, tone, or accent. The voice recognition system then creates a voice template, which is a mathematical code that represents the unique features of the voice. The voice template is stored in a secure database and compared with the voice data of the user when access is requested.
Voice recognition is a natural and convenient way of biometric authentication, as it only requires the user to speak to the voice recognition system. It is also a flexible and adaptable biometric technology, as voice recognition systems can work with different languages, dialects, or vocabularies, and can also recognize voice commands or phrases. However, voice recognition also has some limitations, such as the possibility of voice changes, variations, or imitations, which may affect the accuracy and security of the system. Moreover, voice recognition may be affected by background noise, interference, or distortion, which may reduce the quality and availability of the voice signals.
Advantages and Challenges of Biometric Access Control Systems
As you can see, biometric access control systems use different types of biometric technologies and devices to authenticate and grant access to users.

Challenges of Biometric Access Control Systems
Biometric access control systems also have some challenges that need to be considered and addressed, such as:
Privacy concerns
Biometric access control systems raise some privacy issues regarding the collection, storage, and use of biometric data, which may contain sensitive and personal information about the users. Unlike key cards, passwords, or PIN codes, which can be changed or deleted, biometric features are permanent and irrevocable and may reveal information about the user’s age, gender, race, or emotion. This means that biometric access control systems may expose the user’s biometric data to potential misuse, abuse, or theft, and violate the user’s privacy rights and expectations.
Legal and ethical implications
Biometric access control systems may face some legal and ethical challenges regarding the consent, ownership, and protection of biometric data, which may vary depending on the jurisdiction and the context. Unlike key cards, passwords, or PIN codes, which can be voluntarily given or withheld, biometric features are involuntary and unavoidable, and may not be fully controlled by the user. This means that biometric access control systems may require the user’s explicit and informed consent, and comply with the relevant laws and regulations, such as the General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA), to collect, store, and use the user’s biometric data lawfully and ethically.
Technical limitations
Biometric access control systems may encounter some technical limitations, such as errors, failures, or vulnerabilities, that may compromise the performance and security of the systems. Unlike key cards, passwords, or PIN codes, which can be easily corrected or replaced, biometric features are fixed and immutable, and may not be easily modified or updated. This means that biometric access control systems may suffer from false positives or false negatives, which may result in granting access to unauthorized users or denying access to authorized users, or from system malfunctions or breakdowns, which may render the system inoperable or inaccessible. Moreover, biometric access control systems may be susceptible to hacking, spoofing, or tampering, which may allow unauthorized users to bypass or manipulate the system.
User acceptance
Biometric access control systems may face some user acceptance barriers, such as lack of awareness, trust, or comfort, that may affect the adoption and usage of the systems. Unlike key cards, passwords, or PIN codes, which are familiar and widely accepted, biometric features are novel and unfamiliar, and may not be fully understood or appreciated by the user. This means that biometric access control systems may require the user’s education, awareness, and feedback, and address the user’s concerns, expectations, and preferences, to increase the user’s acceptance and satisfaction of the system.
