Warning: Extremely geeky post follows:
Today, most people have their digital life stored on online servers from various companies. Think Google, Apple, Facebook, Twitter, Dropbox, Instagram and many others. You uploaded your pictures, your music, your daily ramblings, happy and sad thoughts. You use these services to share with others, to send and receive emails, store address books, play music and video, have your files available on any device you want. All great features, no doubt! When your phone breaks, just having to log in to the new one to find all your pictures, contacts and other settings is an amazing and reassuring capability brought by these services, often (perhaps incorrectly) called ‘the cloud’.
But you might wonder: “Where is this data? Who has access to it?“
