Apple publishes new technical details on privacy features - Reuters

The white papers are similar to a security guide that Apple publishes for the iOS operating system that powers iPhones. They cover Apple's photo app, its Safari web browser, the location-based services on its mobile devices and a new service for signing into third-party apps introduced this year that competes with similar services from Facebook Inc (FB.O) and Alphabet Inc's (GOOGL.O) Google. Apple does not make public the code for its operating systems or software, so privacy and security researchers use the descriptions it publishes to understand how those systems work. In the papers, Apple outlines how its new sign-in system tries to prevent the creation of fake accounts in apps, a problem for nearly all app developers that has taken on new importance with the advent of bots on social networks. The company uses machine-learning technology that analyzes whether the device user engages in "ordinary, everyday behavior such as moving from place to place, sending messages, receiving emails, or taking photos," Apple said.
