This is then exploited by attackers to track individuals movements.
Prior research has shown that wireless fingerprinting is present in wireless technologies such as Wi-Fi.
As a result, there are chances of fingerprinting in these devices.
This isnt exactly an easy process.
Prior fingerprinting techniques built for Wi-Fi have relied on a long-known sequence called the preamble.
However, the preambles for Bluetooth beacon signals are extremely short.
Real-World Experiments And Challenges
The researchers conducted initial experiments to test their tracking method in real-world experiments.
The researchers also discovered several challenges that an attacker will face in practice.
For example, changes in ambient temperature can alter the Bluetooth fingerprint.
This means it is unlikely to be a widespread threat to the general public today.
Researchers noticed that just disabling Bluetooth may not necessarily stop all mobile phones from emitting Bluetooth beacons.
