No, we're talking about actual user data. My position is only very small part of the whole story. While my telco can triangulate me, that's not as useful (precise) as you'd think, especially in vertically built-up areas and/or behind walls.
- rad_gruchalski 5y agoNo. Original point: > QR codes aren't effective at all as a surveillance mechanism. Why the hell does the government need to monitor which venues you visit based on QR code check-ins? They literally just ask Apple, Google, or any other big tech company about your phones geolocation and IP log history to monitor your whereabouts. This is about locating a user based on QR code scanned at a venue. All I’m saying: no need to ask Apple or Google. Your telco already knows you have been at a location at the time of the venue.
- emteycz 5y agoMy telco is most definitely not able to determine which particular restaurant, shop or highrise apartment I visited (I know because I have direct experience with requesting this data from telcos via courts and how precise it actually is). Telcos can calculate approximately where I was (with accuracy worse than raw unaided GPS - so ±10m at least, and unpredictably wrong if I'm behind a wall or in a vertically built-up area) at a particular point in time - but they don't know the exact timestamp to look for.
