Bluetooth Security

I remember about two to three years ago there were rumors floating about, concerning how hackers can hijack any Bluetooth enabled mobile phone and download contacts, messages, and pictures, from it. It was a bad time for Bluetooth, since people were questioning its security. Several Bluetooth related discussion boards are filled with similar topics, asking about how to hack a Bluetooth enabled devices - or if it is simply possible.

To tell you the truth, all communication technologies have their own vulnerabilities, including Bluetooth. The Internet needs firewalls and anti-viruses to protect users’ devices, Wi-Fi needs to be properly protected with encryptions and passwords, and Bluetooth is no different. Bluetooth is relatively safer, because it is not that easy to hack a Bluetooth transmission. The hacker – the person trying to get into your Bluetooth enabled phone – will have to be within range; Bluetooth has a range of 10 metres. The hacker could then decode your devices’ pin and sniff transmitted packets, which is again not an easy task to do.

There are ways to protect your devices from a Bluetooth attack. The first is to of course disable Bluetooth on your devices if it is not being used. You can always set your Bluetooth to stealth or invisible; other people will not be able to see your device. Last but not least, only accept trusted connections and avoid accidentally allowing unknown devices to connect to yours.

Bluetooth Headsets

Bluetooth headsets are probably the most popular Bluetooth enabled devices available. It functions as a standard headset that will enable you to make and receive calls, and have a hands-free conversation. The latest version of a Bluetooth headset allows you to listen to stereo music in high quality, and fast transfer rate, all wirelessly. Bluetooth headsets are very useful in daily life, especially when you are working or driving and need to make or receive a phone call.

There are several things you need to consider before buying a Bluetooth headset. First of all, Bluetooth headsets are designed to be practical and comfortable so you should seek a Bluetooth headset that will fit nicely and comfortably on or in your ear. See if it is easy to switch the device on and off, and if the controls – volume, phone controls, etc. – are easy to operate. It should make your life simpler; simple is the keyword here. Check if the headset supports the latest Bluetooth 2.0, and if it is compatible with your phone or other Bluetooth enabled devices such as laptops or personal computers. And of course, look at the headset’s design. You wouldn’t want to use bulky Bluetooth headset in the office.

Getting To Know Bluetooth 2.0

Until about a year ago, we all used the first version of Bluetooth technology. It was called Bluetooth 1.1, before it developed into Bluetooth 1.2. The only difference between the two versions was data transfer rate, with Bluetooth 1.2 being faster than the first one. Bluetooth 1.2 also utilizes HCI (Host Controller Interface) and is completely compatible with the previous version. Recently, a new version of Bluetooth, called Bluetooth 2.0, was introduced. There are a lot of new features available on the latest version of Bluetooth technology, taking Bluetooth usage to a whole new level.

Bluetooth 2.0 is of course faster than the previous two versions; it is stated to be three time faster than the older Bluetooth versions. With EDR (Enhanced Data Rate), you can transfer music, pictures, videos, and files to any Bluetooth enabled devices faster. Ever wonder how you can connect stereo headsets and listen to music wirelessly? That would be the work of A2DP profile available on several enhanced Bluetooth 2.0 devices. No more wires - you can put your music player on your table and still be able to hear your music as long as you are within a 10-metre radius. Now that you know about Bluetooth 2.0, I bet you will start looking for Bluetooth 2.0 enabled devices so you can enjoy the advantages for yourself, right?
