Re: Who creates the hash?
The hash has been called a 'perceptual hash' by Apple, implying that it is not an exact checksum analogue for a file.
Louis Rossmann on one of his recent videos (https://www.youtube.com/watch?v=9ZZ5erGSKgs) was talking to one of his regular commentators who appeared to know the technology being used, and it appears that it somehow measures various features in a photograph such that cropping, altering colours, inserting steganography etc. would not hide the pictures.
I can imagine such a system, certainly running in the cloud with all the AI smarts that exist there, but I'm not sure that I accept that that will actually run on an i-device, at least not without consuming a lot of resource and power. I know Apple have been embedding their neural engine AI processor on their SoCs. Maybe it will only run on devices that have this available.
