Data about exercise routes shared online by soldiers can be used to pinpoint overseas facilities. Sensitive information about the location and staffing of military bases and spy outposts around the world has been revealed by a fitness tracking company.
WHY IT MATTERS: Big data and Internet of things - where every device in the world is connected - has huge potential. At the same time, this enhanced traceability has downsides for privacy and security, as evidenced by this article from The Guardian. Other similar examples in the past have highlighted the possible issues: robbers get caught by police when the photos they post of their robbery includes their GPS location, or face identification cameras in China let government track individuals as they walk the street. We will have to find a solution for this in the future.
