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?

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.

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...
