- doubloon 3y agoi guess the argument is that these images were a needle in a haystack and now you have given the public a supermagnet to go find it. like right now, if someone tries to download old laion and find those images manually, it would probably take them a very very long time. if they had the diff, they would find them in a few minutes. i dont think its a good argument, but its an argument. the researchers found them without a diff so likely someone else can too. so theres not much reason to leave them in that i can tell.
- morkalork 3y agoYes, I get that. But that's not what the researchers did. They used a database of know hashes. Can bad actors not do the same?
- sp332 3y agoI don't think it's easy to get access to the PhotoDNA database. And it would be a service that people query against, so they'd have an audit trail.
- dublinben 3y agoYou're not allowed to have the MD5 hashes these researchers used to find these images, so it's not possible to reproduce this result. These hash databases and APIs are tightly controlled, and only law enforcement, major tech companies and top researchers are allowed to use them.
