Biometrics for Door Access Control

Biometrics is the future of security and access control. We know how organizations are using employing the technology in attendance systems to ensure correct entry and exit recordings in the database. But biometrics is a field that doesn’t cease to amaze and remains largely unexplored for the time being.  A biometrics system uses unique human traits that vary from person to person to identify a particular person or a set of persons. These unique traits can be finger prints, voice control or retina imaging.

We all are accustomed to watching James bond accessing different gadgets and accessing controls to different doors with a touch of finger or a retina scan. Those there are some cool biometric applications for you.

Let us look into a lesser known application of biometrics i.e. door access control.

There are various sections/departments in an organization where access has to be restricted or limited to an extent. For an example, a movie theater restricts entry of the movie goers to certain sections by installing gates that require unique recognition. At these gates, the staff members can use their unique physical traits to request access and enter a particular section.

Door Access Control System

How does biometrics work in case of door access system?

First things first, a unique trait is decided upon to be used as the identifier for access to doors. Let’s say we decided upon fingerprints to be used as the identifier. Now we need to record finger prints of the staff/ people who are allowed to access the particular door. Once the finger prints are recorded, they are to be synchronized with the access control system in such a manner that they recognize the allowed identifiers without any lag or problem.

Now when a person presses his finger against the interface which observes finger prints, the system would either recognize a positive result i.e. matched finger prints, or negative results i.e. unmatched finger prints. In case of positive results, the door which is already locked door is unlocked and the person is granted access. If the result is negative, then the door remains closed and the entry is denied.

This is how unwanted access to certain sections is restricted in organizations that seek security and privacy. Similarly, with the help of biometrics technology a lot of tasks can be accomplished and simplified further.
