A smartphone’s unique Bluetooth fingerprint could be used to track the device’s user–until now. A team of researchers have developed a simple firmware update that can completely hide the Bluetooth fingerprint, eliminating the vulnerability.

    Turn Bluetooth off, super effective

    They were always be ways to fingerprint and active system, you can change the current characteristics that are used, but you cannot make everything the same. There will always be a difference, be it timing, be at packet signing, be it’s electrical signaling, there will always be some way to infer a fingerprint of the system active on the network.

    Because Bluetooth is not use constantly, it’s better to turn it off when not in use, and not even worry about the fingerprinting because you’re not participating

      Yup. Only time I ever turn bluetooth on is when I’m using my game controller or the little speaker I move to whatever room I’m in. If it’s not being used for either of those things, it stays off. I don’t even use it to connect my cell to my computer—that’s what usb is for.
