Apple OS automatically uploads files to the cloud

[Security researcher Jeffrey Paul] was not alone in either his frustration or surprise. Johns Hopkins University cryptographer Matthew D. Green tweeted his dismay after realizing that some private notes had found their way to iCloud. Bruce Schneier, another prominent cryptography expert, wrote a blog post calling the automatic saving function "both dangerous and poorly documented" by Apple.

The criticism was all the more notable because its target, Apple, had just enjoyed weeks of applause within the computer security community for releasing a bold new form of smartphone encryption capable of thwarting government searches - even when police got warrants. Yet here was an awkward flip side: Police still can gain access to files stored on cloud services, and Apple seemed determined to migrate more and more data to them.
