We’ll have to wait and see how good their neural hashing is, but just to clarify the 1 trillion number is the “probability of incorrectly flagging a given account” according to Apple’s white paper.
I think some people think that’s the probability of a picture being incorrectly flagged, which would be more concerning given the 1.5 trillion images created in the US.

- jhayward 5y agoHow is it that you are going to "wait and see how good their neural hashing is"? Do you think there is going to be any shred of transparency about the operation of this system? It is completely unaccountable - starting with Apple and going on to NCMEC and the FBI.
- simondotau 5y agoFrom Apple's technical summary: "The threshold is selected to provide an extremely low (1 in 1 trillion) probability of incorrectly flagging a given account. This is further mitigated by a manual review process wherein Apple reviews each report to confirm there is a match..." So it's 1 in 1 trillion per account PRIOR to manual review in which the odds of error get reduced even further.
