Huh? False negatives and false positives are irrelevant with respect to the utility of the overall system. It means they don't render the system irrelevant.
Intentional false negatives are irrelevant because catching 100% of CSAM was never stated as a goal of the system. And because it's just not realistic to expect to see any real-world use by CSAM aficionados. Anyone savvy enough to understand the principles behind hashing (and trust some command line tool downloaded from Github) is probably smart enough to have better places to store their child porn than an iCloud gallery.
Intentional false positives are irrelevant because there are, depending how you count them, between two and six other layers which would need to be thwarted or exploited in order for intentional false positives in NeuralHash to result in any adverse outcome.

So if the purpose of the system is not to catch persons dealing with CP, what is the purpose? Breaking user's privacy? We have a history of evil intentions masked by fighting against CP, drugs, money laundry and crime in general.
- emodendroket 5y agoThere is pretty much no enforcement mechanism against any crime which we can expect to catch everyone. False positives get bounced out by the safeguards, false negatives wouldn't have been caught in the first place... that still presumably leaves a number of true positives who wouldn't have otherwise been caught.
- kalleboo 5y agoFacebook is catching millions of CSAM images being directly uploaded by people to Facebook/Messenger of all places. There are still plenty of complete idiots trading CSAM that one could see value in apprehending.
- simondotau 5y agoThat's what boggles my mind. I really don't understand how someone could be trading in CSAM without knowing how dangerous it is to trade in CSAM.
- sokoloff 5y agoI believe there is an incredibly wide spectrum of most human qualities and traits. I see no reason to think that general intelligence, technical awareness, utility maximization, impulse control, or risk-reward calculation wouldn’t have similar distributions such that plenty of people would end up in a set prone to share risky material on such channels.

One possibility is that these databases are stuff full of material which isn't actually CSAM. There is no accountability for the content of the databases. Considering the infinitesimal number of prosecutions compared to the claimed number of hits, we should hope that this explanation is actually the truth...
