> The vast majority of Facebook NCMEC reports are hits for known CSAM using a couple of different perceptual fingerprints using both NCMEC's and FB's own hash banks.
Fascinating. Thank you for providing the clarification. I still find that number to be perplexingly huge. If it's indeed correct, one hopes that Apple know what they're getting themselves in for.
Thanks for the kind suggestion, but I'm not going to concede anything on the basis of an assertion made by one person in one tweet, with zero supporting evidence, zero specificity, zero context.
Assuming that number is correct, it means there are orders of magnitude more reports than there are entries in the CSAM database. So even if I conceded that Facebook were reporting over 10 million CSAM images, how many distinct images does this represent? More than four? We have no idea.
How many of those four were actually illegal? Remember, there's a Venn diagram of CSAM and illegal. A non-sexual, non-nude photograph of a child about to be abused is CSAM but not illegal.
This is a serious topic; you don't seem to be taking it seriously.
