Abstract

Bluetooth is an industrial specification for wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers, digital cameras and video game consoles via a secure, globally unlicensed short-range radio frequency.

Bluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) based around low-cost transceiver microchips in each device.

Bluetooth technology can be very effectively used for authentication and authorization purposes. Many levels of security are built into Bluetooth technology. We can utilize all of that to provide different levels of security to our car.

The car lock control can be hard coded so that it responds to commands received from a single transmitter only. The Bluetooth transmitter is identified by using the hardware address which is unique for each transmitter. Another level of security can be added by using the pass key security in Bluetooth. The user will have to enter a pass code to start the engine ignition.

The beauty of using Bluetooth technology lies in the fact that we can use ordinary mobile phones with Bluetooth technology in the place of the transmitter.

So in effect the user can control his car doors and ignition from his Bluetooth enabled mobile phone. This technology has got significance since the number of Bluetooth enabled mobile phones are increasing.
