> to reveal blurred version of the images being hashed
Skimmed your linked paper. It seems they were able to classify hashes up to ~8% top-1 accuracy and ~30% top-10.
Not exactly a blurred version, or any images at all.
So for example, they can say that you probably have images of trees, or images of buildings, but without much other data & very low accuracy.
I'd still be a lot more concerned about them simply flagging political images rather than trying to get a broad understanding of what type of photos I have
