I think it's very interesting. The detection function needs to send data back to the cloud, right?

Does it need to be written into the Kernel? Or how does it work?

I think we're probably not far from the world of Watch Dogs. As for whether it will become 2077, we'll have to wait and see.

There is at least one example of software that contains example CSAM that is obfuscated. It is compared to content on a device or in a cloud storage. At least one person claims to have been able to reverse the process and retrieve the originals. The question in my mind is whose kids seeded this software and what living person has now been immortalized via their likely most-traumatic experience.

Good question. If so, we will be prevented from taking photos when offline. And will pay extra data charges when not.
