I'll Trust You - for Now

The pervasiveness of cloud computing paired with big data analytics is fueling privacy fears among the more paranoid users. Cryptography-based solutions such as fully homomorphic encryption and secure multiparty computation are trying to address these fears, but still do not seem to be ready for prime time. This paper presents an alternative approach using encrypted cloud storage by one provider, supplemented by cloud processing of cleartext data on one or more different cloud providers.
