2. INTRODUCTION
• Bluejacking is sending of unsolicited message over
Bluetooth to Bluetooth-Enabled devices such as mobile
phone, PDA (Personal Digital Assistance) or Laptops,
by sending a vCard (or Business Card) which typically
contain a message in the name field via OBEX (Object
X-change) protocol.
• Bluejacking do not remove or alter any data from the
device.
• The person who is being attacked does not know any
information about the hacker except the name assigned
to the hacker’s mobile phone.

3. TECHNOLOGY USED
• BLUETOOTH TECHNOLOGY.
• vCards (Business Card).
• OBEX protocol.

4. BLUETOOTH TECHNOLGY
• Short private area that uses radio frequencies to
transmit data.
• Has a very limited range , usually 10 meters on mobile
phones and around 100 meters on laptops.
• Operates at Unlicensed Industrial Scientific and
Medical (ISM) band at 2.4 GHz power.
• Connects various devices alike laptop , camera, mobile,
mouse, etc. in a PAN (Personal Area Network) via RF
link through short-range piconets.
• Low power.
• Low cost.
• Has ability to be full duplex ability to transmit data and
voice transmission simultaneously.

5. vCards
• vCard (Versit Card) is a file format standard for
electronic business card.
• Contain name , address information, phone numbers ,
email , birthdays , etc.

6. OBEX PROTOCOL
• OBEX (abbreviation of Object Exchange) is a
communication protocol that facilitates the exchange
of binary objects between devices.
• Helps to exchange business card , data , even
applications.
• Initially OBEX was designed for infrared, latterly
now has been adopted by BLUETOOTH also used
over USB.

• BLUEBUGGING

12. BLUESNARFING
• Stealing of information from victim’s Bluetooth
device often between phone, laptops, PDA’s ,
etc.
• This allows access to a calendar, contact list,
emails and sms and moreover some user can
steal even images and private videos.

physical server provisioning the digital media over
Bluetooth to interested device.
• In some temples which offer ringtone , wallpapers of

17. CONCLUSION
BLUEJACKING is a technique by which we can
interact with a new person and can bring a great change
in the world of advertisement by sending about the
products , enterprises etc. on the Bluetooth.
So we conclude that in future this technology becomes
the key for advertisement to interact with the world.
