Biometric access control systems are changing the way businesses handle their office security. With faultless data gathering, identification, and verification capabilities, biometric access control systems are vital to the security of countless industries and sectors around the world.
What is a Biometric Access Control System?
A biometric system is a way of establishing a person’s identity through chemical, behavioral, or physical attributes and is used in large-scale identity management across a wide range of industries and applications. One of the most common uses for biometrics is providing access control to restricted facilities, areas, or equipment. Unlike other security systems, such as code, password, or access card systems, biometric systems provide access based on who people are rather than what they have in their possession.
A biometric system is basically a pattern recognition unit that gathers specific biometric data from a person, focuses on a specific feature from that data, compares it to a pre-set group of attributes in the database, and then performs an action based on the accuracy of the comparison. There are a lot of characteristics that are used for biometric comparisons, such as fingerprints, irises, hand geometries, voice patterns, and DNA information.
A standard biometric access control system is made up of four main components:
A Sensor Device. A biometric reader, or scanning device, is used to obtain verification data from a person. The sensor unit then forms the key interface between the user and the biometric access control system. The quality and usefulness of the obtained data depend on the camera characteristics since most of the biometric data is composed of images, with the exception of audio-based systems.
A Quality Assessment Unit. Biometric data that is gathered by the sensor device must be evaluated to determine whether it can be processed. Normally, an algorithm is designed and applied to the data to improve its quality. After processing, a set of features is selected from the data set to represent the qualifying identity trait. This is also known as the “Biometric template” and is stored within the system’s database.
A Feature Comparison and Matching Unit. Once the chosen data set has been extracted from the data, it will then be compared to the stored templated and matched to any identical points. The number of matched points between the input and template provides a “Match score”. In a biometric access control system, the matching device usually includes a decision-making device that relies on the match score to confirm a person’s identity.
Database. The biometric system database stores all the information that is needed to process biometric readings. In order to enhance security levels, the biometric system will establish access control parameters with a featured template that is inputted into the system.
Types of Biometric Access Control Systems:
Fingerprint Scanning. This is one of the earliest uses of a biometric access control system which was mainly used to aid criminal investigations. Today, fingerprint recognition technologies are a key feature in many biometric access control systems.
Vascular Biometrics. This system provides an added layer of protection above that offered by fingerprint scanning. Vascular biometrics use near-infrared light to scan the pattern of veins in the user’s fingers.
Facial Recognition. This biometric technology works hand in hand with industrial security camera systems to provide a clear record of employee and guest activities at your business. Facial recognition systems reduce the risk of unwanted access to your business.
Iris Scanning. This biometric access control technology uses the unique pattern found in the user’s eye to provide accurate identification of employees.
Voice Authentication. Voice-activated biometric access control systems can eliminate the need for passwords and employee badges while allowing tiered access to different areas of your business. This system must be installed and monitored by a qualified security company to achieve the most reliable results.
What are the Benefits of a Biometric Access Control System?
A biometric system delivers a high level of identity security than typical proximity-based access control systems. This is because biometric systems use a user’s unique biological information in order to verify and authenticate their identity. This system is safer than using codes or access cards, as these are easier to obtain. Biometric access control systems use features such as fingerprint, retina, voice, and facial recognition, which are extremely difficult to replicate.
The main advantages of a biometric access control system include:
Extra security. Biometric access control is more secure since biometric markers are unique to each user.
Low maintenance cost. Once the installation of a biometric access control system is complete, the maintenance cost is much lower compared to other systems.
It does not require additional devices. With biometric access control, there is no need to use traditional keys, switches, or switching devices since authorization only requires the user’s unique characteristics.
Some disadvantages of a biometric access control system include:
Biometric systems are less convenient in businesses where the “user list” changes repeatedly, such as new staff at an office or frequent business visits.
Installation cost is higher than other access control systems, yet, the cost of maintenance is lower.
In some cases, specific users cannot be identified, which can create issues in the authorization process.
There are times when a combined identification system is used, such as fingerprints and keypads, which can also offer greater advantages and added security.
