Does this really even matter for combatting this? were pedos really so stupid that they were putting their shit on the cloud?
I'm all for stopping pedophiles but this seems like a scary breach of privacy, is an apple person going to look at my young-looking but completely legal nudes? This seems scary.
For any detection logic one has to take the video, .i.e. the series of images in, feed to logic of code, and return results. For a hidden or very big program, the code can as well be,
if nudity
send_to_apple_server()
print("We detected nudity, and flagged this video")
The user cannot differentiate it from well intended code. The right thing to do is not track at all! No "SMART" logic to "HELP"!
