> I know it will never be hundred percent leak proof

A slow leaking ship will still sink. Attempts so far to anonymise public datasets have been terrible and turned into a garbage fire by attackers every time with minimal effort. Don't hand out false promises.

Guess you are looking for fully homomorphic encryption. A long-outstanding problem with lots of smart people working on it, some are doing ok at getting there.

Differential privacy is an area that makes some guarantees about not letting personal information about individuals escape. Might be a useful technique as well.

Agree that strong guarantees about privacy aren't achievable.

Yes, I found this the other day: https://smartnoise.org/

Need to read more about the concept. Anyone with more good resources?

[michealr]

Thats true, a poorly chosen description on my part.

Very cool, had read about homomorphic systems. For fully homomorphic systems has there been successful SAAS like offering allowing use of such a systems? Or do you think its still in the research oriented phase?

[maest]

Not really SaaS, and debatable whether it's successful, but I hear numerai uses homomorphic encryption when providing data for quants to backtest.

EDIT: added qualifier, since i do not know for sure if numerai is using homomorphic encryption.

[kasperni]

Definitely still in the research phase for what you are looking for. Performance is anywhere from 5-15 magnitudes slower than ordinary computations. Yes, magnitudes...

I'm a little rusty but I swear I saw a partial homomorphic encryption scheme for aggregates and analytics. I want to say Enigma conference, '16 or '17? Maybe by Boston University.

The benefit being that while you can run any computatio with a FHE, PHEs are generally faster.

IIRC Microsoft was also doing research on PHEs.

[michealr]

Interesting, did Microsoft bring the research any further?

Might be what I was thinking of. I'm sure you can find other publications as well. I'm no longer at University and I've lost touch with that professor so I'm not sure their current research.
