Biometric Access Control – Next Level Surveillance Act

Examining two of the most eminent features in an access control system and door controller with slave reader operated through smart cards or finger punch for surveillance.

Anti Pass Back – this refers to a process of blocking unauthorized access of unregistered person through a registered employee.

It has been experienced in the offices that unauthorized people access a particular floor with the help of an authorized person with only one access card. In this once an employee who has marked IN by punching the card on access system will need to mark OUT as well to complete one cycle on IN and OUT from the floor, other wise the system won't allow the employee to enter or leave the floor, this feature in turn can block the exit of the person who has entered the floor illegally as he/she won't be able to move out from the floor now.

Feedback Locks – Following the list of various modes of security breach thru access control systems, another one in the list can be a physical barrier which can obstruct a gate from closing, lets suppose an authorized employee opened the door with the access card and placed a chair, rod or any other object before the door creating a barrier and not letting it to meet the armature plate to get closed. This act can make the doors open for everyone. What is particular about feedback locks is the siren or beep sound which gets installed with the doors so that if any object restricts the door in getting closed, the siren or beep sound starts ringing informing everyone about the suspicious act.

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.
