The database you described has existed for a while. It's called social media.
People voluntarily post their minute-frequency gps location, workplace, political and religious leanings, sexual preferences, views on current events, and an exhaustive list of friends, family, coworkers, and other associates. Not to mention hundreds, if not thousands, of geo-tagged pictures of themselves over the years, along with a list of the other people in the frame, as well as a written discussion of the events photographed.
