It will also match completely different images, that why there is "neural" bit to discard images that e.g. don't have nudity from the pool of matches.

- pseudalopex 5y agoThe neural bit doesn't do that.[1] Maybe you got it mixed up with the iMessage nudity detection. [1] https://www.apple.com/child-safety/pdf/CSAM_Detection_Technical_Summary.pdf#page=5 https://www.apple.com/child-safety/pdf/CSAM_Detection_Techni...
- intricatedetail 5y agoDid you read it? They use neural network to discard false positives, because perceptual hash alone is not reliable. It's pretty much the same concept I described.
- pseudalopex 5y agoPlease quote what you think supports your claim. "Indeed, Neural-Hash knows nothing at all about CSAM images. It is an algorithm designed to answer whether one image is really the same image as another, even if some image-altering transformations have been applied (like transcoding, resizing, and cropping)."[1] [1] https://www.apple.com/child-safety/pdf/Security_Threat_Model_Review_of_Apple_Child_Safety_Features.pdf#page=10 https://www.apple.com/child-safety/pdf/Security_Threat_Model...
