Bluetooth is a tool that seems to work like magic, doesn't it? After all, transferring files or listening to music without using cables is something that seems to be very difficult to understand. That resource, according to researchers at the University of California, also allows our cell phones to be tracked by other people. He was curious to know if Is it possible to be tracked by the cell phone's Bluetooth? See now.

What do scientists say about it?
According to the researchers, Bluetooth communication, due to an error, carries a unique fingerprint. That's because all chips, during the manufacturing process, developed a small imperfection, which makes each one unique. Thus, it is possible to identify them through this sign, even if they were produced in scale.
Fortunately, it's not like the device's owners can be tracked all the time, at least not from a distance. For this, it is necessary to be close to the target, which makes the “tracking” kind of pointless, isn't it? However, this range may depend on the type of chip, hardware and Bluetooth communication potential of each of the devices used.
In addition, a certain level of expertise with technology is required, since it is not such a simple process to do. The researchers themselves make it clear that despite not being an expensive task, it is something that counts much more on luck than the technological knowledge of the attacker.
How to track Bluetooth?
If you are still curious and want to take this test, know that the task can be quite complicated. For the process to be done, it is necessary to isolate the signal from the target device, which will allow you to find this fingerprint. Next, a receiver must be somewhere where the cell phone tends to be used. If combined with a friend, it is simpler, but it is almost impossible to perform the feat with someone random.
In fact, the more the Bluetooth device transmits, the more likely the attacker will pick up a transmission when a user or target walks by.
