Take a look at Google Private Join and Compute[1]. But be aware that the problem you frame is an unsolved research problem with an active global community. The topics you are looking for are applications of secure multiparty computation and homomorphic encryption. Also, be ready for something as simple as a column join to take 24 hours per query.
