Looked at the network logs and the JS, did some testing, there's a caveat here. For an encryption demo you might expect your secrets to be generated locally, they do the compute on something they can't read, you compare their results to your original plaintext; (imo at least) the point would be that it isn't physically possible for them to cheat.
Here, you literally download client_secret.bin from their server, so they have control over the keys and evaluators. So two things. First, the per user key flow would be several minutes for per user keys, the evaluator bundle would be in the 100s MB to GB realm. Second, there's no way for us to tell the difference between them really doing FHE or decrypting with the key. To be clear, not evidence it's fake, just not total proof it's real. Really hope it's real, been a field I've been following for awhile.

Big if true! One of the caveats here is that the file size seems to balloon 341 times.

> Image classification without the server seeing the image.
Does a given plain image always result in the same encrypted payload?

Super interesting work - should become default for sensitive data over time (finance / legal / ...)

I think they only trained on dogs with floppy ears, because it is very confident the German Shepherd is a cat.

It's pretty confident this calculator is a cat.

What's the use case for this?

Kudos to the KULeuven alumni, but I am curious if the US finances research on homomorphic encryption still /s
