De-identification can mean a lot of things, but when dealing with location histories one at a time, few of them help very much. How many people take the same route that you do to work? How many do it at the same time you went and stopped at the same store on the way back at the same time you did? How many took the same vacations? How many live in the same building? The intersection of these sets very rapidly approaches one person.
The question is the extent to which the aggregation obscures all this.
- 14 5y agoHow about who had access to it? Did they watch their gf movements while she was out? Will we be seeing down the road that it was abused and a jealous lover tracked their partner? This whole thing has already been played out in history and we know this is a bad thing. I am shocked HN crowd is defending this behaviour this time. This is not something we should accept as a society.
