Security has become prime concern at all
major buildings in India. Especially security and access of
individual at buildings with maintenance of automated log is the
solution. Every individual without any human intervention is
tagged with his access rights to through the various doors of the
building and a complete automatic log to his access detail with
date / time is maintained at the server.
The backend software controls the various hardware like
controller, door locks in a synchronized manner for a fast and
efficient locking / unlocking mechanism with data capture at
multiple points simultaneously. The software further provides
option for on screen viewing of reports, search and deny access
options to individual by administration. Network enabled software
provides viewing of reports at multiple nodes at the same time
within the network even at remote location.
SOLUTION
All individual of the building are
registered in BIOMETRIC ACCESS CONTROL TERMINAL for secure access.
The doors will be fitted with automatic door locks and BACT on
finger scan, the terminal will automatically verify the
authenticity of the individual and check whether he/she has the
access through this door or not. On correct verification of his
access rights the door will automatically unlatch and the
individual will be granted access. Incase of unauthorized access
the door lock will not unlatch, hence denying access. The total
above process is logged by the computer automatically and reports
can be generated online and also verified for a particular period
incase of any breach in the security.
The above-mentioned system is a
vital tool to help in maintaining security at buildings and is
widely used internationally.
System review
The BACT is with built in controller. It
manages multiple access control terminal installed at various doors in
an organization. the low cost ,small, attractively packaged front end
readers are connected to the controller in star connection. It
provides fields configurable intelligent engine for taking care of any
organization s access control requirement. The terminals can be
configured using a front end software, all the access decisions are
taken by the terminal making it truly a standalone system independent
of PC. It can be used in Online mode for larger PC controlled
building management system. Multiple terminals can be networked
suitable hardware for larger application.
What is Biometrics?
Biometric technologies are defined as
automated methods of identifying or authenticating the identity of
a living person based on unique physiological or behavioral
characteristic. Biometric can provide very secure and convenient
authentication for an individual sine they cannot be stolen or
forgotten and are very difficult to forge.
-
A
physiological characteristic is a relatively stable physical
characteristics .such as an individual s fingerprint hand
geometry, iris pattern or blood vessel pattern on the back of
the eye. This type of biometric measurement is usually
unchanging an unalterable without significant duress to the
individual.
-
A
behavioral characteristic is more a reflection of an
individual’s psychological makeup.
A signature is the most common behavioral
biometric used for identification. Because most behavioral
characteristics vary over time, an identification system using
these must allow updates to enrolled biometric references.
BIOMETRIC
SYSTEM COMPONENTS AND PROCESS:
Three major components are usually present
in a biometric system.
-
A
mechanism to scan and capture a digital or analog image of a
living persons biometric characteristic.
-
Software for storing , processing and comparing the image.
-
An
interface with the applications system that will use the result
to confirm an individual’s identity.
Two different stages are involved in the
biometric system process- enrollment and verification.
ENROLLMENT:
The biometric image of the individual is
captured during the enrollment process (e.g using a sensor for
finger print scanner, microphone for voice verification ,
camera for face recognition , scanner for eye san) The unique
characteristics are then extracted form the biometric image to
create the biometric template. This biometric template is stored
in a database or on a machine readable ID card for later use
during an identity verification |
