Assuming the images do as claimed match the hash, they must also match the ‘visual derivative’ in order to trigger a match.
The system isn’t as easily fooled as is being claimed here.
- toxik 5y agoYou have misunderstood. NeuralHash is the visual derivative.

The NeuralHash is what matters, solely. [1] https://www.apple.com/child-safety/pdf/CSAM_Detection_Technical_Summary.pdf https://www.apple.com/child-safety/pdf/CSAM_Detection_Techni...
- malf 5y agoThere’s literally a page showing “NeuralHash + visual derivative” in the thing you posted.
- toxik 5y agoEdit: I did find it, but only because somebody else pointed it out. Guess I suck at reading. Also search for "derivative" failed to find it.
