BLUEJACKING

1. INTRODUCTION

Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled

devices such as mobile phones, PDAs or laptop computers, sending a vCard which
typically contains a message in the name field (i.e. for bluedating or bluechat) to another
Bluetooth enabled device via the OBEX protocol. Bluetooth has a very limited range;
usually around 10 meters on mobile phones, but laptops can reach up to 100 meters with
powerful transmitters.

Bluejacking allows phone users to send business cards anonymously using Bluetooth
wireless technology. Bluejacking does not involve the removal or alteration of any data
from the device. Bluejackers often look for the receiving phone to ping or the user to
react. In order to carry out a bluejacking, the sending and receiving devices must be
within 10 meters of one another. Phone owners who receive bluejack messages should
refuse to add the contacts to their address book. Devices that are set in non-discoverable
mode are not susceptible to bluejacking.

Mobile phones have been adopted as an everyday technology, and they are ubiquitous in
social situations as users carry them around as they move through different physical
locations throughout the day. As a communicative device, the mobile phone has been
gradually taken up in ways that move beyond merely providing a channel for mediated
conversation. One such appropriation is bluejacking, the practice of sending short,
unsolicited messages via vCard functionality to other Bluetooth-enabled phones. To
choose the recipients of bluejacks, senders complete a scan using their mobile phones to
search for the available Bluetooth-enabled devices in the immediate area. A bluejacker
picks one of the available devices, composes a message within a body of the phone’s
contact interface, sends the message to the recipient, and remains in the vicinity to
observe any reactions expressed by the recipient.
 BLUEJACKING
The messages tend to be anonymous since the recipient has no idea who has sent the
bluejack, and the recipient has no information about the bluejacker, except for the name
and model of the bluejacker’s mobile phone. Because of Bluetooth’s short-range
networking capabilities, bluejacking can only occur between actors who are within 10
meters of each other, which makes this activity highly location-dependent. Contrary to
what the name suggests, the bluejack recipient’s phone is not hijacked; that is, the phone
is at no time under the control of the bluejacker.

2. Origin
This bluejack phenomenon started after a Malaysian IT consultant named “Ajack” posted
a comment on a mobile phone forum. Ajack told IT Web that he used his Ericsson
cellphone in a bank to send a message to someone with a Nokia 7650.
Becoming bored while standing in a bank queue, Ajack did a Bluetooth discovery to see
if there was another Bluetooth device around. Discovering a Nokia 7650 in the vicinity,
he created a new contact and filled in the first name with ‘Buy Ericsson!' and sent a
business card to the Nokia phone.
“A guy a few feet away from me suddenly had his 7650 beep. He took out his 7650 and
started looking at his phone. I couldn't contain myself and left the bank,” he says.
Ajack then posted the story on a mobile Web site and other people started trying it out.
“I gave it the name bluejacking (taken from the words Bluetooth and hijacking) and it has
just taken off from there.”
He says bluejacking is common in Malaysia and is happening everywhere there are lots
of Bluetooth devices.
Bluejacking has become popular among young people wanting to play practical jokes. A
13-year-old named Ellie from Surrey in the UK has started a dedicated bluejacking site
called bluejackq. The site explains what bluejacking is and also has forums where people
can share their bluejacking experiences.

3. HOW TO BLUEJACK

Assuming that you now have a Bluetooth phone in your hands, the first thing to do is to
make sure that Bluetooth is enabled. You will need to read the handbook of the particular
phone (or PDA etc) that you have but somewhere in the Menu item you will find the item
that enables and disabled Bluetooth.

Now, remember that Bluetooth only works over short distances, so if you are in the
middle of Dartmoor then BlueJacking isn't going to work for you (unless the sheep have
mobile phones these days!) so you need to find a crowd. BlueJacking is very new so not
everyone will have a Bluetooth phone or PDA so the bigger the crowd the more likely
you will have of finding a 'victim'. The Tube (yes, Bluetooth works underground), on the
train, in a Cafe or standing in line are all good places to start.

You will now need to create a new Contact in your Phone Book - however rather than
putting someone’s name in the Name field you write your short message instead - so for
example rather than creating a contact called Alan Philips you would write - "Hey, you
have been BlueJacked!" instead (or whatever message you want to send)

Now select the new contact and from the Menu of the phone choose "Send via
Bluetooth". This is a facility available within the Mobile Phone that was designed to send
a Contact to someone else - useful in Business when trading names and addresses,
however we are now going to use it to send our message that was contained in the Name
field of the contact - clever eh?

Your phone or PDA will start to search the airwaves for other devices that within range.
If you are lucky you will see a list of them appear, or it will say that it cannot find any. If
the latter happens then relocate to another crowd or wait a while and try again. If you
have a list of found devices then let the fun begin.
 BLUEJACKING
Unfortunately, almost every Bluetooth enabled device will not yet be configured with a
useful name - so you are going to have to guess. Some devices will be called by their
Phone manufacturer (e.g. Nokia, Sony) or maybe a random string. Try one at random and
look around to see who grabs their phone and then looks perplexed when they read your
message :) If you want to name your Phone so it appears as a name in the list on a
BlueJackers phone see how to name our phone .You can build a library of contacts with
predefined messages.

3.1 Mobile

The various steps involve in this are as follows:

1. First press the 5-way joystick down.

2. Then choose options.

3. Then choose "New contact"

4. Then in the first line choose your desired message.

5. Then press done.

6. Then go to the contact.

7. Then press options.

8. Then scroll down to send.

9. Then choose "Via Bluetooth"

10. Then the phone will be searching for enabled Devices.

11. Then press "Select"

3.2 Personal computers/laptops

1. Go to contacts in your Address Book program (e.g. Outlook)

2. Create a new contact

3. Enter the message into one of the 'name' fields

4. Save the new contact

5. Go to the address book

6. Right-click on the message/contact

7. Go to action

8. Go to Send to Bluetooth

9. Click on other

10. Select a device from the list and double click on it

4. Software tools

The procedure for bluejacking as stated or explained earlier are very long and confusing.
To avoid this we have developed some software to do bluejacking in an easier way. So by
downloading that software on your personal computer or on your Bluetooth configured
mobile phone you can do it directly by just searching the enabled Bluetooth device and
send unsolicited messages to them. There are many software tools available in the market
and there name is according to their use. Some of them are as follows:

4.1 Bluespam

BlueSpam searches for all discoverable Bluetooth devices and sends a file to them
(spams them) if they support OBEX. By default a small text will be send. To customize
the message that should be send you need a palm with an SD/MMC card, then you create
the directory /PALM/programs/BlueSpam/Send/ and put the file (any type of file will
work .jpg is always fun) you would like to send into this directory.Activity is logged to
/PALM/programs/BlueSpam/Log/log.txt.
BlueSpam also supports backfire, if you put your palm into discoverable and connectable
mode, BlueSpam will intercept all connection attempts by other Bluetooth devices and
starts sending a message back to the sender.

4.2. Meeting point

Meeting point is the perfect tools to search for Bluetooth devices. You can set your
meeting point to a certain channel and meet up with people you’ve not met before.
Combine it with any bluejacking tools and have lots of fun. This software is compatible
with pocket PC, palm, Windows.

4.3 Freejack

Freejack is compatible to java phone like Nokia N-series.

4.4. Easyjacking (eJack)

Allows sending of text Messages to other Bluetooth enables devices.

4.5. Proximitymail

4.6. Freejack

5. USAGE OF BLUEJACKING

Bluejacking can be used in many fields and for various purposes. The main fields where
the bluejacking is used are as follows:

- Busy shopping centre

- Starbucks

- Train Station

- High Street

- On a train/ tube/ bus

- Cinema

- Café/ restaurant/ pub

- Mobile phone shop

- Electronics shop (e.g. Dixons)

The main use of bluejacking tools or bluejacking is in advertising purpose and location
based purpose. Advertising on mobile devices has large potential due to the very personal
and intimate nature of the devices and high targeting possibilities. We introduce a novel
B-MAD system for delivering permission-based location-aware mobile advertisements to
mobile phones using Bluetooth positioning and Wireless Application Protocol (WAP)
Push. We present a thorough quantitative evaluation of the system in a laboratory
environment and qualitative user evaluation in form of a field trial in the real
environment of use. Experimental results show that the system provides a viable solution
for realizing permission-based mobile advertising.

6. CONCLUSION

Bluejacking is technique by which we can interact with new people and has ability to
revolunerise market by sending advertisement about the product, enterprise etc. on the
Bluetooth configured mobile phone so that the people get aware about them by seeing
them on the phone.

Now a day it is used in sale promotion or sale tools and in dating. This technique is used
in many fields like cinema , train station, shopping malls ,mobile phone shops etc. now a
days there are new tools available in the markets by which bluejacking can be done. The
basic technology behind bluejacking is similar to Bluetooth because we can do
bluejacking in the mobile or PADs or computers or laptop configured with Bluetooth.

Now a day new and new techniques are developing using Bluetooth. Some of the latest
news is :

Bluetooth Technology Now Standard in Cars ,BlueParrott Bluetooth B100 Wireless

Headset ,Motorola & Burton Launch Bluetooth Snowjackets ,Bluetooth shipment units
3m a week ,O'Neil Launches 'The Hub' Bluetooth Snowboard Jacket ,CellStar Launches
Bluetooth Web Surfer ,Emergence of new Bluetooth usage_models ,Heart Monitor Sends
Crucial Information to Cell Phones ,Impulsesoft Delivers Stereo Music Over Bluetooth
,TDK Systems builds on the benefits of Bluetooth ,Impulsesoft Delivers Stereo Music
Over Bluetooth .

So we conclude that in future this technology become the key for advertising and to
interact with world and to get the location messages on the phone when you are
somewhere out. Bluejacks are location specific. We first wanted to determine the types of
places where bluejacks took place. The data indicate that bluejacking is an activity that
primarily occurs in public spaces, outside of the home. Bluejacks frequently occurred in
public transportation locales (23.4%), stores and shopping malls (32.1%) and restaurants
 BLUEJACKING
(9.8%), bars (11.2%) and cafes (7.3%) but almost never at home (0.7%). This suggests
that bluejackers are targeting strangers, presumably taking advantage of anonymity,
opportunities for interaction and available Bluetooth enabled devices afforded by densely
populated public spaces. There are few security issue which can be minimized by taking
some simple precaution like when you do not want to be blue jacked just off your
Bluetooth.
