Traditionally, access control systems use passwords or key cards to control who is granted access and who is not. However, in recent years, there has been a huge shift towards biometric systems due to advances in technology.
Biometric access control is a type of access control system that determines a person’s identity based on their biological attributes. This can include physical, chemical or behavioural attributes that are unique to every individual.
Biometric systems are more reliable than traditional systems as they do not rely on passwords or key cards that can be forgotten, lost or stolen. This means they are more secure, hence why they are favoured by high security businesses.
Biometric access control systems work using pattern recognition technology. They are commonly made up of a sensor, a quality assessment unit, a feature comparison and matching unit and a database.
The sensor and quality assessment unit scan the user’s biological data and check the data is detailed enough to use against the information stored in the database. The feature comparison and matching unit then searches the database for a match to the user’s data using an algorithm. If a match is found, the user is granted access however if there is no match, the user cannot enter.
Often, people worry about the security of storing biological data and its implications on personal privacy. All modern biometric access control systems use a combination of algorithms and a one-way encryption system so the data stored cannot be used to identify the users.
There are lots of different types of biometric access control systems available. Every day examples include fingerprint and face identification that can be seen in smartphones.
Less common biometric access control systems include voice recognition, iris scanning and vein mapping. While they are not as widely available, these methods are more reliable as they don’t change over time.
Every industry can benefit from the use of access control systems. Whether you want to improve the security of your office building or restrict access to a high security area, access control is an ideal solution.
Access control isn’t only beneficial for security purposes, it provides real time data about who is on your premises. This means you have an accurate register in the event of an evacuation, ensuring the safety of everyone in the building.
