US technology giant Apple is fighting Chinese claims that the iPhone threatens national security through its ability to track and time-stamp a users location. We appreciate CCTVs effort to help educate customers on a topic we think is very important, Apple said Saturday in a statement in Chinese and in English on its China website. We want to make sure all of our customers in China are clear about what we do and we dont do when it comes to privacy and your personal data. Ma Ding, director of the Institute for Security of the Internet at Peoples Public Security University in Beijing, told Chinese state broadcaster CCTV on Friday that the frequent locations function could be used to gather extremely sensitive data, and even state secrets.
