Check out Enigma [1]. It allows a 3rd party to perform computations on encrypted data using distributed, secure multi-party computations. Thing is it's at least 20x slower than computing over plaintext, and nodes will have to be compensated with fees, much like Bitcoin miners. Still, for safety critical industries, this could be a very useful tool. Especially if the government steps in and mandates such a protocol.
