alt Hacker NewsNot to mention that your android/ios device is still shipping a bunch of bluetooth tokens for "track and trace" system. Cryptographically signed to you.

It is encrypted ciphertext rotated every 10m in lockstep with your Bluetooth identifier.
You will need to turn off your Bluetooth if you want to stop advertising a rotating random number.
The only difference with the contact tracing is that a key, on the device, can correlate the ciphertext. I have it off because the utility was never demonstrated.

That's a bit of an oversimplification that makes this sound more concerning than it is. Not that it's 100% un-concerning, but I suggest that anyone concerned about this read the linked docs. It really was designed to be quite privacy preserving, though it's obviously a difficult challenge in this context.
