Language Support for Multiple Privacy Enhancing Technologies

Privacy is one of the critical aspects in the design of computing systems. Various techniques are being used to enforce privacy, such as information flow control, symmetric/asymmetric cryptography, secure computing enclaves, partial homomorphic encryption and differential privacy. These mechanisms should ideally be combined in complex software systems as they offer different properties and performance trade offs. Unfortunately, reasoning about the privacy properties of such combination is still an open research problem. In this paper, we present our vision on a programming language in which we incorporate different privacy preservation techniques in a common programming model.
