The problem with hashes is, that you cannot prove what the original image was without actually getting caught with csam.

So basically, a whistleblower takes photos of some very incriminating documents, someone gets accused of eg. money laundering, hashes of those images get added to the "csam" database, and you find the first person (via metadata) who had that image on their phone.

Also, in some more repressive countries, an image of a famous cartoon bear photoshopped to look like some president can be added, and all the people who look/have/download images (memes) like that, can get put on a "list".

But would the system not insist images are hashed by it? I mean; I would think it’s not a weird demand that if this is to protect children (which it is not, at least not only) that the image hashes are solely for that purpose or otherwise not valid and thrown out by at least an AI. I know it’s naive but it seems you want the image with the hash and if someone gets flagged and it’s some money laundering doc, then it should be dismissed before you get out on a list.

The hashes are likely provided by some outside agency who is fine with transferring the hashes, but would have qualms about transferring multi-petabytes of the matching CSAM images.
