A catalog of naturally occurring images whose Apple NeuralHash is identical
My take on this is that the system is by and large useless.<p>It won't catch anything but the dumbest of dumb criminals, because those who care about CSAM can surely figure out a better way to share images, or find a way to obfuscate their images enough to bypass the system (the lower the false positive rate, the easier it must be to trick the system).<p>So what's left when all the criminals this is supposed to catch have figured it out?<p>False positives.  Only false positives.<p>Is it really worth turning personal devices into snitches that don't even do a good job of protecting children?<p>Also, numbers about false positives must be taken with a grain of salt because of the non-uniform distribution of perceptual hashes.  It might be that your random vacation photos and kitty pics have a 1-in-a-million chance of a fapo, but someone who happens to (say) live in an apartment that has been laid out very similarly to a scene in pictures appearing in the CSAM database may have a massively higher chance of fapos for photos taken in their home.
