Re: sensor calibration fingerprinting

Hi Nick  -

Apologies for “de-lurking” in the middle of a thread…

Just one quick thought in-line below:

I think it would be a good idea for any mitigation to apply to Gravity too. My reason for saying so is a bit tangential, but I hope it makes sense. At a recent event on quantum technology, several speakers expressed the view that quantum sensor technology would reach the “mass” market significantly before general purpose quantum computing. One of the variants is gravity sensors (!), which, in due course, they expect to be able to apply to navigation - “mapping” the gravitational topology around you, and matching it to a reference dataset. Of  course, if  the reference dataset exists, it can be used to geolocate you regardless of which technology is used to measure your “local” gravitational topology.

Hope this is relevant,
