How Ashton Kutcher’s ‘non-profit start-up’ makes millions from the EU’s fight against child abuse on the net::The ‘non-profit start-up’ Thorn, founded by actor Ashton Kutcher, is a driving force behind the EU’s campaign to scan the net for child abuse material. Newly public documents and financial information obtained by Follow the Money reveal the blurred boundaries between Thorn’s do-good public face and the powerful business behind it.

Safer, Thorn’s flagship software product, was launched in 2018. Backed by Microsoft’s PhotoDNA technology and with technical support from Amazon Web Services, Safer is designed to detect child abuse by matching hash values of pictures or videos uploaded by users with a database of millions of known CSAM images.

I don't really understand how this works. Are the hash values like meta data? Is there a way to maintain privacy but also check for illegal material?

It sounds like they have a database of CSAM images, so they're likely hashing parts of the suspected image or video and searching for that hash in the database

This isn't like an anti-virus system. You can't just catalog them all. It's too easy to create. Hell, with the advent of LLMs and AI-generated images, it's going to be even easier to create.

Too easy to create and too easy to foil the hash, unless it’s some kind of highly sophisticated feature-based hashing.
