Found this visual analysis of "anonymized" cell phone data interesting. How is it truly anonymized if you can track the movement of the devices? Correlating data over an extended periods can help you identify the device owner just be seeing its daily movements (home locations, work locations, frequently visited places, etc.).
If anyone could explain how this isn't concerning I would love to hear more information on what is done with data like this to make sure it's truly close to anonymous. Would like to hear the other perspective.
It has been clear for a while now that many data sets can be "de-anonymized" be they tax records or particularly location data. I have seen fitbit "anonymized" data of my own movement about our farm, of my wife's typical running route through our woods, of patrol routes around fire bases overseas and even movement of analysts within the pentagon.
Is it creepy, to be sure yes, but honestly it can't come as a surprise to you as a member of a "hacker news forum" that dozens of popular 3rd party apps collect and sell your location data "to improve your experience". Apps that you and I and more or less anyone else told "go ahead and collect this data and sell it to your partners".
