> They are using a library of human verified images to compare the hashes

I didn't get that from the article, could you point to a source on this?

Images are submitted by over 1400 organizations[0] like the FBI and NCMEC, although the inner-workings of the database aren’t public and I can’t find a source or confirmation of every image actually being human-verified. The closest is how the "Child Victim Identification Program" helps identify victims in these images.

Of all of the discussion, my brain has only keyed in on the child porn aspect. It just now clicked that if a missing kid is in a photo (even if not porn), it could help ID the missing kid. Some runaway at the age of 13 gets photographed in a group of other kids just doing teenager things.

So even if not running hashes against known porn, it could still be doing facial recognition. Wonder what kind of implications that would have for people in witness protection or battered spouses and other legitimately "disappeared" people.

Think of the children will erode everything. It is magic.

Directly said in the article:

“Users’ photos, converted into a string of numbers through a process known as “hashing”, will be compared with those on a database of known images of child sexual abuse.”

> The system has been trained on 200,000 sex abuse images collected by the US non-profit National Center for Missing and Exploited Children.

Also from the article.

‘Trained’ being important.
