Keeping Your Blue Tooth Devices Secure
By Andrew Kelly

Blue tooth devices have changed the world of technology to newer, faster and easier methods than traditional ones and have allowed technology to advance faster than ever before. Blue tooth technology works by using radio frequency to transfer data between other blue tooth devices such as mobile phones, computers and personal digital assistants (PDAs). Ericsson (Sweden) was the first to develop this technology in 1994 and the name was derived from King Herald Bluetooth Blatland who ruled part of Scandinavia in 190AD. It was said that he helped unite his part of the world, which is why the name Blue tooth was used, implying that the technology would be used to unite the world. However, with any new technology, people can be wary of using it out of fear of safety or security reasons.

How Blue Tooth Devices Work

Blue tooth devices work by using radio frequencies to communicate with each other, instead of using traditional cables and leads. For the communication to work properly, both devices need to have their “profiles” set up correctly so that the blue tooth devices can understand what the other is telling it (similar to speaking in the same language). Therefore, before purchasing a blue tooth device, it is essential that the buyer knows what they want the device for and what they want it to do so as that the right item can be matched up. If set up correctly, blue tooth devices have the capability to communicate at a connection speed 3-6 times faster than that of broadband internet.

Blue Tooth Device Security

One of the myths of blue tooth technology is that people can browse other blue tooth devices freely, making their own personal data open to thieve and con artists. This is due to cases being reported of people “hacking in” to blue tooth devices as well as cases of internet fraud as seen in past years. This, however, is not true, as a blue tooth device cannot be browsed without the user first setting up the security features. Blue tooth devices can also be set up so that the device is “invisible” to other users, meaning the device cannot be picked up. It is possible to set all devices up so securely that they require password and encryption up to 128-bits before they can be accessed. This, of course, means keeping these details secure, and making sure you understand the technology you own beforehand.
