Abstract

This is a research explaining a scenario that would benefit from using computers

and information technology. The report is about the Card Access System. This system is

worthy because it can be applied in many different places such as homes, hotels, companies

and condominiums. It is the ability to log and keep track of who access a particular door and

when it was accessed is a great advantage when it comes to investigating a security breach or

theft.

Besides that, the research is also explain the functionality, advantages,

disadvantages, and impact of the technology in the organization, as well as identify and

discuss the similarities and differences with at threetechnologies covered in the CITW

Module. Three modules areHuman Aspects of Computing and Enterprise ComputingThe writer is also come up with few recommendation that can be done in order to solve some

problems enhance the current situation.

Acknowledgement

I am very pleased to this assignment because it is my first time. I am also

pleased to say that I learned a lot of things in my Computing in Work Place classes. Before

Introduction

Nowadays there is a shortage in free space epically in the modern cities like

Kuala Lumpur and because of that people try hard to find the most secure and comfortable

to live in. So they start to build condominiums and those condominiums should have a good

security system in order to attract the customers. One of these condominiums is Sky Villa

condominium.

Sky villa is the organization name that my research is about. It is

condominium located in serdang, near south city plaza, UPMuniversity,Kuala

Lumpur, Malaysia. This condominium was built about seven years ago. It is content of twomain buildings. Each one is content of twenty floors and each floor is content of twenty

apartments. This condominium is owned by different owners. The subservices in this

condominium are service apartment, with security, swimming pool, gym, sauna room. There

are about 3200 residences in this condominium and it is necessary to secure all of them.

Therefore the organization finds a way to which is the access card system. {Sky Villa

Current Scenario

Now, more than ever, security is fast becoming a concern for many. From large

private corporations to Small Medium Enterprises, from Private Condominium to Public

Apartments, more and more people are installing security systems, protecting what matters

most, and gaining for themselves the peace of mind protection they desire.

Before this technology most of organizations were depending on the human

guards and all those old methods, but after this technology the organization gets the benefit in

many different ways such as it will reduce the expenditure on employing human security.

There are various companies that manufacture card-based access control systems

for doors and elevators. The best products are built on a foundation of versatility. Physical

access control systems should satisfy a wide range of needs, suitable for all budgets.

Strong sturdy doors with good locks are the front line defense against break-in. However no

matter how good the lockset, how sturdy the door, its greatest weakness lies in the way we

manage the distribution and allocation of keys. As keys are cheap and easy to duplicate, it

poses a security risk whenever a key is lost. Do we simply replace the lost key or do we

changed the lock? And what if disgruntled residences dismissed or had resigned? Do we

know for a fact that they did not hold any duplicates?

Electronic Card Access System offers a better alternative as their authorization to your office

is programmable. A residence that leaves the condominium can be notes simply by

programming the reader.

Functionality

Any card access system will consist offour basic elements. Depending on the size and

purpose of the system, there may be many additional types of devices however the four basic

elements are:

1. Cards

2. Readers (possibly equipped with keypads)

3. Access control panels (controllers)

The Card

A card (or transponder) is a passive electronic device that relies on a reader to provide the

necessary power for start-up and communication. Any access card simply carries a set of

binary numbers (ones and zeros) that are used to identify the cardholder. HID Global

produces technology-based identity and access management and identification, HID makes

cards that are capable of carrying this kind of binary data including:

Magnetic Stripe

Wiegand (swipe)

125 kHz Prox

MIFARETM contactless smart cards

13.56 MHz iCLASS contactless smart cards

There are special characteristics of both MIFARE and iCLASS cards

and readers that will be briefly addressed at the end of this document.

The means of encoding data on the card and conveying the data to the

reader varies according to the technology involved. In every case,

however, the data on the card is a string of binary numbers of some

fixed configuration and length.

In the vast majority of cases, the data on the card is comprised only of the format that will

eventually be received by the controller.

In extremely rare cases, an additional code will be carried on the card that is linked to a

specific group of readers. This ID code will be stripped off by the reader and only the format

sent to the controller.

The card itself has no awareness of the makeup of its format, nor is it aware of any access

privileges for the cardholder. That information exists only at the controller, and possibly the

host (if present).

The ReaderA reader is an electronic component of a physical access

control system. Usually a self-contained unit, the is an

autonomous device that performs the single purpose of

interfacing to a card and providing an output to an access

control panel.HID makes readers that are compatible with

each of the five types of cards listed above. In every case,

each reader can only talk to its corresponding card type sinceeach of the technologies is unique.

All standard readers using any listed technology simply

convert the binary card data to Wiegand (or other) Protocol

and send it without changes to the controller.

Certain proprietary readers will receive the site-specific ID code from

matching proprietary cards. Those readers will strip away the ID code and

send only the remaining binary data to their controller.

The reader itself has no awareness of the makeup of the card data format,

nor is it aware of any access privileges for the cardholder.

The Access Control Panel (Controller)

When the controller receives the data from the reader, its software begins the process of

deciding whether or not to grant access. This is usually done in several stages.

Does the length of the data format match what the controller is expecting? Some controllers

are designed to only accept a certain length of data (34 bits for example.) If the data from the

8


9/15


assignment

2010

card is too long or too short, the controller may ignore it completely. Other controllers may

have a special access denied for a non-matching format length.

Does the format structure make sense to the controller? If the length is acceptable, the

controller then breaks the binary string down into its component parts. These might include:

o Facility Code

o Site Code

Does the Facility Code match? The controller will examine the data to determine if the

Facility Code portion matches the one that has been programmed into the controller. Some

controllers can support many different Facility Codes, possibly even multiple formats. If the

Facility Code doesnt match, access will be denied and a log message generated. Does the Site Code match? If the format contains a Site Code or other secondary identifier,

it will be handled just like the Facility Code above.

Is the Card Number within the allotted range? If yes, the decision process will continue. If

no, access will be denied and a log is generated.

Is the Card Number in memory? If yes, the process continues. If no, access is denied and a

card not in memory log is generated. Is the card valid at the reader at this day and time?

Yes, access will be granted and the lock relay will be activated. If no, a log message will be

generated that will identify the reason for denial.

Advantages

This technology has many advantages. Some of them are:

Light in size. It is easy to be carried to anywhere.

It will reduce the expedition of the human guards.

It is fixable. It can be replaced in another place or door.

Anyone can depend in it this is because you do not have to

worry ofhonest less of the human guards.

Time Attendance report. Another important advantage is that

this organization uses this technology as attendance evidence in any

crimes situation.

Disadvantages

The card is easy to be stolen. That simply because it small that

make the holder to forget that it is with him or not.

Anyone can use it without the owner promotion. And that

could harm the owner in if a crime happened. The system will show his

name as an evidence.

Impact of the Technology

Access control is a vital concern for a business of any size, today. With the rising

number of attack crimes, and by this technology the organization can make high level of

security. And that will benefit the organization by raising the number of customers. This

technology also helps the organization by reducing the amount of money that without this

technology the organization would spend it to hired human guards.

Similarities

Chapter 1 Human Aspects of Computing

10


11/15


assignment

2010

There are some similarities between access card system and the

Human Aspects of Computing chapter in the CITW module. One of the

similarity is that HCI and access card system are designed a computer

systems that support people so that they can carry out their activities

productively and safely.HCI is used to describe the interaction between a

user and a computer and in the access card there is an interaction between

the user and the computer.

Another similarity is the card shape. The design of the card

made to by comfort the user by soft plastic that is because to make

usability and simplicity.

Chapter 13 Enterprise Computing

In this chapter access card system is like distribution systems

because all the information in one computer and the readers are in many places.

Also this system is like the information system because it monitors and

only gives access to the allowed people to enter.

Also in this chapter access card system is considered as Information

System in the Enterprise because it is set of hardware which is the card and the readers,

software which is the controller, data, and people that work together to produce safety. The

access card system is considered as Transaction processing system TPS because it Captures

and processes data from day-to-day transactions in the organization.

Chapter Ethical & Legal Issues

In this chapter access card system is similar to this topic in the unauthorized

access. When the owner lost his\her card anyone can enter the building easily. Another

similarity is information privacy. This system protracts the information of the user by

11


12/15


assignment

2010

putting them in the server not in the card. And that make it secure if the card lost that no one

can read the information because the information are not in the card the number is only in the

card.

Differences

Chapter 1 Human Aspects of computing

There are some differences between Access Card System and the Human Aspects

of computing chapter. One of those differences is Health Concerns of Computer such as

Computer vision syndrome CVS and Repetitive strain injury (RSI). But in access card

system there is not health concern.

Another different in this topic is that the computer in the access card system is

always on and that against the green computing because the electricity is on and that

consider as waste while using computer.

Chapter 13 Enterprise Computing

In this topic the different is functional unit in the Enterprise and the functional

unit in the access card system. In the Enterpriseare usually departments and centersbut in

this system the functional unit are the three elements of the system which are card, reader

and controller.

12


13/15

2010

Another different is the access card system is similar to the TPS but not to the

CMS or CAD programs because it does not make computer aided. It is just a software

that in a server (computer).

Chapter Ethical & Legal Issues

In this topic the different is that in the access card system does not have cookies

in the card reader because it just check the card and send the number to the computer and the

computer see if the number is correct will allowed by sending back to the reader to open, so

the reader does not store any information in it that can be cookies.

Another different is, since anyone could lost his\her card the system cannot tell that

the person is having the right card or not and that could be unauthorized access.

Recommendation

In this part I want to recommend this organization (Sky villa) to use modern cards

that give the controller ability to cancel the card when is been lost. That will make the

lost card useless. That because when the owner lost his or her card and someone find it he

could easily enter the building without any notice. I also recommend sky villa to make a

yearly check and updates the owner's information. That because when the residence leave

the condominium he\she left the card to another person and that person uses it under the old

owner name.

Conclusion

To make a long story short, Access Card System is a vital program to Sky VillaCondominium. And it improves the security of this organization. I hope that every houses or

organization would get the benefit of this system.
