Such data may be useful, it says, to “identify every person who attended a protest or rally based on their smartphone location or ad-tracking records.” Such civil liberties concerns are prime examples of how “large quantities of nominally ‘public’ information can result in sensitive aggregations.” What's more, information collected for one purpose “may be reused for other purposes,” which may “raise risks beyond those originally calculated,” an effect called “mission creep.”
Terrifying. Thank you for posting.
