Wonder how fine-grained you'll be able to purchase data. Say you can buy data in a 2km circle minimum from a given point, and results with anonymized/aggregate.

Wonder how fine-grained you'll be able to purchase data. Say you can buy data in a 2km circle minimum from a given point, and results with anonymized/aggregate. Then you buy 2 more circles, find out where they all intersect - bam, got yourself data for a given point. Same as the old Tinder tracking exploit.
