Looked at your FR homepage... I like it :-)
What do you do? I’m in embedded systems.
Remember that a smartphone can be operated out-of-band.
The normal cell frequencies are far too cluttered to be useful for surreptitious monitoring... sending data out as normal cell data is far too risky for serious work.
thx
over the years I’ve focused on many different areas... from UI, server, distributed near real time, to embedded. these days, mesh networks and distributed systems are my focus as well as anything extremely large scale
as such, an agent running on the phone monitoring sounds about right. it’d be the right way to solve the problem, uploading when local wifi is available and all has been quiet for a while (emergency mode would also be built in if the agent determined potentially ‘blowing cover’ was warranted)
