" three researchers have crafted a long-sought version of private information retrieval and extended it to build a more general privacy strategy. The work, which received a Best Paper Award in June 2023 at the annual Symposium on Theory of Computing, topples a major theoretical barrier on the way to a truly private search."

Let’s take a moment and acknowledge that it was never hard to make searches private.

It’s just that doing that requires trusting a company not to fuck with you behind the scenes and sell you out, and ensuring that doesn’t happen is fucking hard

The point of this cryptography is that you don't have to trust the company implementing it not to do that, as long as you trust the software doing the retrieval.

Unless you do it all yourself, it will never be trustless.

Just like your favorite phone app, in the end you will have to trust the actual code, and you will have to trust that the actual app on your actual phone is from the actual source they claim. Do you feel lucky?
