Swift has been adding support for things like non-copyable types that should help with writing performance sensitive parts.

Check my comment here for some intuition: https://news.ycombinator.com/item?id=41115179 Basically the server does not know, it just computes with every possible value. And the result turns out to be what the client was inte

In this PIR model the server has to read the whole database, otherwise it would be easy on the server to see, that these rows were not accessed and therefore they are not the one the client queried. In this PIR model the server runtime is O

A very simple PIR scheme on top of homomorphic encryption that supports multiplying with a plaintext and homomorphic addition, would look like this: The client one-hot-encodes the query: Enc(0), Enc(1), Enc(0). The server has 3 values: x, y

> That's a strange use of 'use'? Clearly, talking to some software over the network is 'using' it? The point is that the proprietary client software was not used.

I thought that this is a way to downsize: instead of supporting two orgs, merge them and the costs hopefully go down?

So people want to be progressive and use cryptocurrency that is not tied to a government. But when things go wrong they run to the FBI and FTC both run by the government.

Perceptual hashes are quite reversible. It is not a cryptographic hash that is hard to reverse.

The encryption is data dependent. The homomorphic computation itself cannot be data dependent. Homomorphic encryption says that even if you see all the intermediate encrypted values, you will not know what the encrypted input or output valu

“Alfred Vaino Aho” this a the first time I looked it up in full (with the middle name) it seems like a Finnish or maybe Estonian name. I am wondering if he has Finnish or Estonian heritage.

I do not believe this is going to work at all. Analyzing encrypted data should not reveal anything actionable. Even when analyzing unencrypted data from clients. I do not see a way to actually catch wall hackers. The reason why one cannot
