Apple's latest mobile software update, iOS 10, launches on Sept. 13, and offers a new setting that will give users much more protection against advertiser tracking. "The current iPhone operating system, iOS 9, already features a 'limit ad tracking' option that users can toggle on or off by going to Settings > Privacy > Advertising. The setting will look the same in iOS 10, but it will act a lot differently," according to a Business Insider report. The Future of Privacy Forum explained that "advertisers can currently target specific groups of iPhone users (such as 18-34-year-old males in London interested in football), identified using their unique ID number, which is known as an IDFA (Identifier for Advertising)," according to the report.
