A simple software fix could limit location data sharing

The "fix" is carriers simply choosing not to track you, which they could always do but don't want to.

It seems like a good idea. But carriers have no incentive to limit the data they collect.<p>I wonder what incentives to do so might look like?

I skimmed through the paper, what isn’t clear to me is how the original Registration Procedure is modified exactly. How is the Authentication Procedure done by the AUF when it doesn’t know the shared key K between the USIM and the network?<p>Can you elaborate a bit on that? Is every USIM using the same shared key?<p>Thanks!

I&#x27;m co-author of this research (with my colleague Paul) -- happy to answer any questions.

Can either of you recommend resources or tools for learning how to design good protocols?

Why doesn&#x27;t android have an os level permission manager, so if I decide to not give location to maps, the os would simply say no signal and continue to work. Same for sms access or contacts or phone. I saw one ROM do this, realme it was I think but apps apparently see this and they complain so no point.<p>BTW, why does truecaller on android 10 show an overlay after a call when settings page specifically disables it ?
