You need the intersection of both, which this hypothetical doesn’t account for. In terms of planting, it’s much easier to do that already across the many, many cloud services that secretly scan on the backend. Going a whole weird route just to get images into a hash database, and then the matching images onto the device, that then get independent human verification seems totally unnecessary if you’re a state agent. Why do something so complicated when there are easier routes to go?
