> It proved that it was technically feasible, and was "privacy preserving". Didn't their paper disproved by reversing the perceptual hashes to reveal blurred version of the images being hashed, and Apple basically said "that's fair, it's not as robust as we wanted, let's visit this later"? If not, I'll happily stand corrected, but please share sources. Addenda: - Apple's original paper: https://web.archive.org/web/20210807165030/https://www.apple... - Paper breaking the hash: https://arxiv.org/abs/2111.06628 Edit: The second one is the wrong paper. I’ll find and link the correct one tomorrow.…

> Don't you think modern image analysis tools such as llms will be easily defeated by measures such as adding colored rings? The LLMs think one specific mystery plant in my garden hiding behind the hedge is velvetleaf; no, wild cotton; no, linden; no, hibiscus; no, mulberry; no, knotweed; no, paulownia; no, catalpa; no, hydrangea; no, grape vine; no, pokeweed. Many of these claims were trivial for me to falsify with a quick image search, they don't look much like each other or my mystery plant. The things the AI "identified" were often simply not true of the photo. Basically, even with…

Yes, I did some more research on this as well. Apparently perceptual hashing is also susceptible to some pretty simple attacks: https://arxiv.org/pdf/2111.06628.pdf
