Technology used for sending unsolicited messages over Bluetooth enabled devices.

Receiver does not get to know who has sent the message to it. It only receives the message along with name and model of the sender's phone.

Range of bluejacking is equal to the range of Bluetooth. It is around 10 meters for mobile phones, and about 100 meters for laptops.

Bluejacking exploits a Bluetooth device's

ability to discover other nearby Bluetooth

devices.

A bluejacker normally send only a text

message, but now it has now become possible

to send images or sounds also.

Bluejacking does not involve the removal or

alteration of any data from the device.

Bluetooth

OBEX

VCARD

Bluetooth is a wireless technology that provides short-range communications

It is proposed to replace the cables connecting portable and/or fixed devices.

Bluetooth works using radio signals in the frequency band of 2.4GHz and supports data transfer rates of up to 3Mbps.

Bluetooth can transmitting voice, data, video and images.

OBEX stands for Object Exchange.

Heart of file transfer over Bluetooth.

It can be used to exchange all sorts of

objects, like files, pictures, calendar

entries, and business cards.

vCard is short for virtual business card.

Address Book exchanges contact

information with other programs

primarily through vCard.

It has .vcf filename extension.

Bluejacking is risk-free since the

recipient has the option to decline the

message received. It can create little

annoyance.

User awareness

Disable device when not in use

Use an unidentifiable device name

Set device to non- discoverable mode when not in use

Use non-guessable PIN codes

Perform pairing only when absolutely required.

It can be used in malls for advertisement purposes. As you cross their shop, you can get a message or any latest scheme they are providing on that day, etc.

They can be used at railway station to give you information about various general rules and about train timings, etc.

It can also be used at café, restaurant, cinema, mobile phone shop or at any electronic shop to provide you various information regarding them.

Bluejacking is a technology that can provideyou with lots of information as you pass by.You may not notice all such things when youare going through any road, etc. but now byjust looking at your phone you can get allthe latest information, latest schemes goingon in any shop, etc. without even enteringthat.But obviously for some people, it is only

something for fun and only those people aremaking inefficient use of it and hencemaking its name bad.
