Bluetooth

Bluetooth is a short-range wireless technology that connects electronic devices, including cell phones, printers, digital cameras, and handheld computers. Bluetooth is designed to exchange data at speeds up to 720 Kbps and at ranges up to 10 meters.

The technology of Bluetooth could take the computing world by storm. Mobile users will have the ability to access the Internet and service providers by their proximity alone. Interfaces will extend beyond that of human-computer interface to include autonomous device-to-device communication. Merely walking by a particular cluster of appliances could allow your Bluetooth device to be probed for information that you may or may not want to disclose. Similarly, walking near a vendor or advertiser will open a connection to your device, which these parties could use to push desired or unsolicited information your way. You might say that the problem could be eliminated were the user required to enter a PIN to authorize the exchange. Yet this solution poses a challenge that compromises the system’s core concept and functionality; it would be immensely irritating for a user to repeatedly have to enter the PIN, using one, or possibly multiple, Bluetooth-enabled devices. Further, the user might already be out of range before even getting the opportunity to enter the code.
