Abstract :
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.
