This isn’t a normal file hash. It’s not SHA or bcrypt. A wide variety of states (1s and 0s) can have the same hash. The idea is to take an image and have all of its possible derivatives create the same hash. For example, if a hash was made of the Mona Lisa, any copy no matter how large, small, black and white, would have the same hash. Think of all the ways the Mona Lisa could be transformed and still be the Mona Lisa. The combinations of ones and zeros would be in the billions. If not more. And all those possible combinations of ones and zeros go back to the same “hash.” That’s extremely resourceful intensive. My guess is that they are going to transform the images into a very low resolution, black and white thumbnail. Then compare it against known abuse images that have been similarly transformed. Or they’re using AI. They might be using AI. Either way, it’s guesswork. How many images might be transformable to the same black and white thumbnail. I don’t know.
