We recently learned that Apple might be analyzing the images we upload to the iCloud servers. Now the fact is, that they have implemented a checking mechanism, but in this video, Apple’s Software Chief, Craig Federighi, explains what is happening to your images when you use iCloud Libraries.
There is also a check done on images received in Messages for a child's device, which warns of it being unsafe. This analysis is performed on a database that is on-device, so there's no communication between your phone and an online service.
With this video, I learned what actually goes on when we sign up to a cloud service. Documents are analyzed so they can be searched for easily, images get scanned to say what objects are in them, and with this change, I think Apple wants to use it in an important way. I am all for protecting children and to have the authorities aware of any illegal events, but the fact that Apple can check what's on our devices came as a shock. I thought I owned the devices — I paid for them. It is an eye-opener seeing to what degree Apple can access and get into our devices.
