How Much Does Your Cell Phone Company Know About You?
Remember a story a couple of years ago about a German politician, Malte Spitz, who asked for and received 6 month’s worth of his personal data from his cell phone company? He received 35, 831 pieces of information about himself. He then turned it over to Zeit Online, a German newspaper site. They added to this information his Twitter posts and created an interactive map of where he went and what he did for the 6 months.
Germany apparently has a privacy law that provides for obtaining this information, I’m not sure if the United States has something similar. If it did, we probably would have seen something similar from a US citizen.
