Of course there is. It's rather trivial to correlate the previous UUID
to the new one when you also have access to the corresponding IP addresses.
Then implement some kind of ping service that send that frequently
changed UUID over an anonymizing network, maybe Tor.
It doesn't have to run all time, it could be a monthly timer that start
a small instance of a Tor client and send the ping with the monthly
UUID. I am elucrubrating here, but this could be refined.
Now, how to avoid fake pings? the same can occur with fake updates
requests used for approximating current installation counts.
You need to be serious about data collection and approach it with a
security mindset “how could I hijack the system and betray users trust”
not “of course my data users are good they will never try anything evil
I can collect everything I get my hands on and think later” (the kind of
credulous US thinking that gave us Cambridge Analytica).
That’s what the GDPR is about. It’s *your* responsibility as data
collector to think about how data could be used, it’s *your* problem to
protect it, it’s *your* problem if it’s misused, you can not make it
available on a platter for others to do evil things with and claim it’s
those people’s problem.
