Bluetooth to Bluetooth Essays Bluetooth to Bluetooth Essay Bluetooth to Bluetooth Essay 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 metres (32. ft) on mobile phones, but laptops can reach up to 100 metres (328 ft) with powerful (Class 1) transmitters. 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. 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. We conceptualize bluejacking as a violation of possessional territory. Inspired by Goffman, we propose that the mobile phone is a possessional territory as a result of the intimacy and continued contact between mobile phone users and their phones.A possessional territory, in our usage, is an object that engenders attachment and defense by those who perceive possession and can be referred to as a personal effec t. Possessional territories function egocentrically; that is, they move around with their owners who maintain and exert regulatory control, such as the definition of settings. Since we characterize the mobile phone as a possessional territory, we adapt the category of violation, defined as a temporary incursion where gaining control is not necessarily the goal as a likely and appropriate category of infringement in this context.We also propose that bluejackers are attempting to personalize their experience of public space by engaging in the violation of others’ possessional territories through the act of illicit and anonymous messaging. Visitors to public spaces can engage in habitual behaviors at a specific location, such as picking a favorite parking spot that one can return to on each successive visit, to gain a sense of familiarity to locations that are frequently re-visited.These physical environments then hold enough significance to inspire defense among those who inhabit them and defensive behaviors, which can range from defining a personal space within a conversation or while using a tabletop work-surface. Typically, an inhabitant of a public place tends to personalize a location if he or she feels that the social conventions of a space allow one the license to mark a territory. Bluejackers, however, ignore the conflict between the control exerted by the bluejacker and the lack of defensive measures that can be taken by the recipient when his or her possessional territory is violated.To gain a further understanding of why bluejackers would engage in a practice that disrupts the social conventions of public space, we ask the following research questions: 1. What are the characteristics of the public spaces in which bluejacking occurs? 2. What are the alternative social conventions that might arise from the practice of bluejacking? 3. What implications does this appropriation have for the design of mobile social systems? Origin This bluejack phenomen on 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. Bl uejacking 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 lso has forums where people can share their bluejacking experiences. BLUEJACKING TECHNOLOGY As we know that 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. So bluejacking is based on Bluetooth technology which is explained bellow. Bluetooth technology Bluetooth Technology was developed to solve the simple problem of eliminating the connector cable.The idea is to replace the cables that are needed to accompany portable devices carried by many mobile travelers with a low-cost, secure, robust RF link. Orig inally Bluetooth marketed to small handheld devices such as cell phones and laptops. As the Bluetooth standard emerged successfully into society, the world demanded more. It is reported on Lets Go Digital in an article written by Ilse Jurrien that three new Bluetooth products are qualified every day and 10 million Bluetooth units are shipped per week. Bluetooth is so efficient, effective, and secure that even the IEEE approved the 802. 5. 1 Standard for Wireless Person Area Networks based on the Bluetooth specification. What is Bluetooth? Bluetooth is defined as a wireless technology that provides short-range communications intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. There are three key features of Bluetooth; robustness, low power, and low cost. The Bluetooth standard provides a uniform structure enabling a wide variety of devices to seamlessly, and wirelessly, connect and communication with each other.Bluetooth devices connect and communicate via RF link through short-range piconets. Bluetooth devices have the ability to connect with up to seven devices per piconet. Each of these devices can also be simultaneously connected to other piconets. The piconet itself is established dynamically and automatically as Bluetooth enables devices enter and leave the range in which its radio operates. The major pro of Bluetooth is the ability to be full duplex and handle both data and voice transmission simultaneously.The differentiation of Bluetooth from other wireless standards such as Wi-fi is that the Bluetooth standard gives both link layer and application layer definitions which support data and voice applications. Bluetooth comes in two core versions; Version 2. 0 + Enhanced Data Rate and Version 1. 2. The primary differences being Bluetooth 2. 0 has a data rate of 3 Mega byte per second whereas Version 1. 2 has only a 1 Mega byte per second data rate. Both are equipped with extended Synchronous Connections (eSCO), which improves voice quality of audio links by allowing retransmissions of corrupted packets.Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2. 4 to 2. 485 GHz, using a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec. Bluetooth is modulated using adaptive frequency hopping (AFH). This modulation has the capability to reduce interference between wireless technologies sharing the ISM band. It does this by having the ability to detect other devices using the ISM band and use only frequencies that are free. The signal itself hops between ranges of 79 frequencies at 1 Megahertz intervals to minimize interference.The devices themselves are categorized into range ability. There are three classes of devices each covering a select range. Class 1 devices are mostly used in industrial cases and have a range of 100 to 300 meters. These devices take more power than the standard devices you and I are accustomed to in our daily routine and therefore are a bit more expensive. Class 2 devices are most commonly found in mobile devices and the most commonly used. Items such as cell phones and printers are Class 2 devices and have a range of 10 to 30 feet and use only 2. milli-Watts of power. Finally, Class 3 devices have the shortest range of up to 1 meter and include devices such as keyboards and a computer mouse. Class three devices therefore require the least amount of power and are in general the lease expensive. Maximum Permitted Power (mW) | Maximum Permitted Power (dBm) | Range (approximate) | Class 1 | 100 mW | 20 dBm | ~100 meters | Class 2 | 2. 5 mW | 4 dBm | ~10 meters | Class 3 | 1 mW | 0 dBm | ~1 meter | 2. 1. 1 Bluetooth Piconets Let’s say you have a typical modern living room with typical modern stuff inside.There’s an entertainment system with a stereo, a DVD player, a satellite TV receiver and a television; there’s also a cordless t elephone and a personal computer. Each of these systems uses Bluetooth, and each forms its own piconet to talk between the main unit and peripheral. The cordless telephone has one Bluetooth transmitter in the base and another in the handset. The manufacturer has programmed each unit with an address that falls into a range of addresses it has established for a particular type of device. When the base is first turned on, it sends radio signals asking for a response from any units with an address in a particular range.Since the handset has an address in the range, it responds, and a tiny network is formed. Now, even if one of these devices should receive a signal from another system, it will ignore it since it’s not from within the network. The computer and entertainment system go through similar routines, establishing networks among addresses in ranges established by manufacturers. Once the networks are established, the systems begin talking among themselves. Each piconet hops randomly through the available frequencies, so all of the piconets are completely separated from one another.Now the living room has three separate networks established, each one made up of devices that know the address of transmitters it should listen to and the address of receivers it should talk to. Since each network is changing the frequency of its operation thousands of times a second, it’s unlikely that any two networks will be on the same frequency at the same time. If it turns out that they are, then the resulting confusion will only cover a tiny fraction of a second, and software designed to correct for such errors weeds out the confusing information and gets on with the network’s business. 2. . 2 The Bluetooth Architecture The Bluetooth architecture is divided into two specifications: the core and the profile specifications. The core specification discusses how the technology works while the profile specification focuses on how to build interoperating device s using the core technologies. The RF Layer The Bluetooth air interface is based on a nominal antenna power of 1mW (0dBm) with extensions for operating at up to 100 mW (20dBm) worldwide. The nominal link range is 10 centimeters to 10 meters, but can be extended to more than 100 meters by increasing the transmit power to 100 mW.The Bluetooth Baseband The basic radio is a hybrid spread spectrum radio that operates in a frequency hopping manner in the ISM band. As stated earlier, the band is divided into 79 one Megahertz channels that the radio randomly hops through while transmitting and receiving data. A piconet is formed when one Bluetooth radio connects to another Bluetooth radio. Both radios then hope together throughout the 79 channels. The Bluetooth radio system supports a large number of piconets by providing each piconet with its own set of random hoping patterns.The Bluetooth frame consists of a transmit packet followed by a receive packet. Each packet can be composed of mult iple slots (1, 3, or 5) of 625 us. Below is a single slot frame. Multi-slot frames allow higher data rates because of the elimination of the turn-around time between packets and the reduction in header overhead. The method which Bluetooth radios connect to each other in a piconet is fairly simple. IT is called a master/slave design. The master radio can be connected up to seven slave radios at any given time.Any Bluetooth radio can become a master or a slave radio. At the time of formation the piconet configuration is determined. Usually, the connecting radio will become the master, although, most devices have a master/slave swap function that allows the roles to be reversed. In order for the piconet to be established by a Bluetooth Radio, the radio must have two parameters available, that is, the hopping pattern of the radio it is to be connected to and the phase within that pattern. All Bluetooth radios have a Global ID which is unique to the system.The master radio shares its Glo bal ID with other radios. The other radios that receive the Global ID become slaves and provide all other radios with the correct hopping pattern. IT is the master who provides the clock offset with the slaves in the piconet, providing the offset into the hopping pattern. Usually, radios not connected to the piconet are in stand-by mode. While in stand-by mode, radios are listen for other radios to find them, which is called Inquiring, and are listening for a request to from a piconet, which is called Paging.In the event a radio issues an Inquire command, a listening radio will respond with an FHS packet that includes the devices Global ID and clock offset to give the inquiring radio at list of available Bluetooth radios within the local range. A Bluetooth radio will page another radio with its Global ID to form a piconet. The radio that was paged will respond with its Global ID and the master radio will pass the radio that was paged and FHS packet. The radio that was paged loads th e paging radio’s Global ID and clock offset in order to join then master’s piconet. . 2 vCard file format vCard is a file format standard for electronic business cards. vCards are often attached to e-mail messages, but can be exchanged in other ways, such as on the World Wide Web. They can contain name and address information, phone numbers, URLs, logos, photographs, and even audio clips. The vCard or Versitcard was originally proposed in 1995 by the Versit consortium, which consisted of Apple Computer, ATamp;T Technologies (later Lucent), IBM and Siemens.In December 1996 ownership of the format was handed over to the Internet Mail Consortium, a trade association for companies with an interest in Internet e-mail. vCard is accompanied by a proposed standard for exchanging data about forthcoming appointments called vCalendar since superseded by iCalendar; the Internet Mail Consortium has issued a statement that it hopes that all vCalendar developers take advantage of the se new open standards and make their software compatible with both vCalendar 1. and iCalendar. The following is an example of a VCard file containing information for one person: BEGIN:VCARD VERSION:2. 1 N:Gump;Forrest FN:Forrest Gump ORG:Bubba Gump Shrimp Co.

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 enab led.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.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. T ry 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: . 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 . 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 3. 3 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: 3. 3. 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.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. 3. 3. 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. 3. 3. 3 Freejack Freejack is compatible to java phone like Nokia N-series. . 3. 4. Easyjacking (eJack) Allows sending of text Messages to other Bluetooth enables devices. 3. 3. 5. Proximitymail 3. 3. 6. Freejack 4. 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 Hig h Street On a train/ tube/ bus Cinema Cafe/ 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. 4. 1 Bluetooth location based system In terms of location proximity detection for mobile phone users the obvious choice is Bluetooth which, despit e previous predictions of its demise, is in fact increasing its growth and Nokia is predicting a year-on year increase of 65% in 2006. There are already a small number of mobile Bluetooth proximity applications in existence which are often described as mobile social software (MoSoSo) and can be viewed as evolutions of Bluejacking.Bluejacking was/is a phenomenon where people exploit the contacts feature on their mobile phone to send messages to other Bluetooth enabled devices in their proximity. Bluejacking evolved into dedicated software applications such as Mobiluck and Nokia Sensor which provided a simpler interface, and in the case of Nokia Sensor, individual profiles could be used to initiate a social introduction. In terms of this particular application it could be regarded as a business orientated application of the Bluejacking phenomenon.Consumers are becoming increasingly aware of the use and benefits of Bluetooth as demonstrated in the widespread use of Bluetooth dongles th rough which the users can connect their desktop machines to these devices. Other initiatives for Bluetooth have been seen in the automotive and medical industries in that manufactures have begun to include Bluetooth access in cars and medical monitoring equipment. According to analysts [11], Bluetooth is currently present in 65% of all mobile phone handsets thus making a system such as the one described in this paper, a very practical and worthwhile scenario.This location based system enables Bluetooth to be used as a means of targeting users with specialized content in a specific area at a given time. For example, users in a supermarket could be informed about a certain discount offer based upon their purchasing habits. Such messages can be sent to all the users in the area with a Bluetooth enabled mobile handset or PDA. In order that the system can service a diverse range of users and devices no client side application is required thus nothing has to be installed. The information is presented in a very familiar and simple form of a text message.Figure 3 shows the basic layout of a system for transmitting messages to all the devices in a given area. The system uses object exchange protocol (OBEX) over Bluetooth to send the information to target devices. Licensed by Bluetooth SIG from IrDA, OBEX has become even more popular than during its original period as means of transferring business details. OBEX is transport neutral, as with the hypertext transfer protocol (HTTP), which means that it can work over almost any other transport layer protocol. OBEX is defined as one of the protocols in Bluetooth and sits over RS232 serial cable emulation (RFCOMM) protocol.Moreover, OBEX is a structured protocol which provides the functionality to separate data and data attributes. A clear definition of each request can be given which helps distinguish one request from another. Use of other protocols such as RFCOMM or logical link control and adaptation protocol (L2CAP) requ ire the applications sending and receiving information to know how the data is sent and when to send the reply. Like extensible markup language (XML) OBEX provides structure to the data being sent in contrast to other protocols such as RFCOMM which basically send bytes. 4. 2 Bluejacking s a market channel Bluetooth offers a new communications channel to marketers. But the technology needs to be respected if they are to avoid alienating consumers according to a white paper from Rainier PR. Stephen Waddington, managing director of Rainier PR, turns wireless sleuth. The marketing industry is never slow to jump on a new communication channel and exploit it for its own ends. The telephone, email, SMS text messaging and the web have all become a standard part of the marketing toolkit, the latter having a marked impact on the way in which organizations communicate with their audiences.Now there is a new mobile communication platform called Bluetooth and both the marketing and technology co mmunity are debating whether it offers a new opportunity to be exploited for marketing gain. 4. 3 Marketing opportunity This mechanism by which messages can be sent between Bluetooth devices – predominantly mobile phones – has provoked discussion within the marketing community as to whether Bluetooth could be used as a promotional communication channel. Bluejacking offers three distinct opportunities for marketers: 1. Viral communicationExploiting communication between consumers to share content such as text, images and Internet references in the same way that brands such as Budweiser, Honda, Trojan Condoms and even John West Salmon, have created multimedia content that has very quickly been circulated around the Internet 2. Community activities Dating or gaming events could be facilitated using Bluetooth as a channel to communicate between participants. The anonymous nature of bluejacking makes is a superb physiological tool for communication between individuals in a localized environment such as a cafe or pub 3. Location based servicesBluejacking could be used to send electronic coupons or promotional messages to consumers as they pass a high street shop or supermarket. To date SMS text messaging has been used with mixed success as a mechanism to send consumer’s location based information Rainier PR believes that viral communication and to a lesser extent event based activities offer the greatest opportunity for bluejacking as a marketing mechanism. Already companies are looking at ways of exploiting the technology in these two areas. London, UK-based TagText has made available a series of urban avatars available free for consumers to send each other.The company is tight lipped about its ultimate product and goals but has done a superb job of raising its profile by making available a series of free media properties. What is clear is that TagText wants consumers to send TagText characters to each other and raise the profile of the company . Herein lies one of the key benefits of Bluetooth. Unlike any other mobile communication mechanism it is absolutely free – there are no subscription charges and no costs associated with sending a message. The rise in text-based bluejacking couldn’t have been more timely for TagText’s launch.Not only can we capitalize on the trend, but using images adds a new dimension that even most bluejackers haven’t yet considered, said Russell Buckley, director and founder of TagText. Buckley admits that Bluejacking would not suit everyone, but for brands that want bleeding edge youth credibility
