There's proably, over the last year of your movements, a point which you've made a purchase that can be linked to you. Maybe more than one, and those can be matched against your behavioural data. Or maybe they have parking information.

Perhaps you deal only in cash, and never give your name to a commercial entity (Hotel, gun retailer, car rental or seller...) -- but for most people that isn't true.

I also don't see why anyone would need your exact address. The only use-case that comes to mind is to send you postal mail. If they have your SIM/IMEI/phone number/full name (see above) and behaviour patterns, if and when they want to approach you "in person" that would be easy?

[ed: come to think of it, pair this data with an archive of public web cams, and you could probably a) automatically pick out faces, and b) match recurring faces with location data, to c) pair faces with recorded data streams. Makes all those cameras in the UK seem even more creepy.]

If there is any continuity to your phone usage, then that is you as an individual that is being tracked. That's what it means for a person to have an identity: continuity in behavior patterns.

It's safe to assume those several dozen people don't share your phone. And even if they did, that's a level of familiarity that means you are among a group of people that probably operate as an economic unit. Nobody is stealing you identity here: they are assigning you one.

They don't care about the house you live in, they care about the zip code, so what you propose is irrelevant. A cpg brand says "tell me where do segments which buy from Retailer XY at location Z live?" and gets an answer. That's what this technology does.
