Privacy-Preserving Computation (Position Paper)

摘要

Private data is commonly revealed to the party performing the computation on it. This poses a problem, particularly when outsourcing storage and computation, e.g., to the cloud. In this paper we present a review of security mechanisms and a research agenda for privacypreserving computation. We begin by reviewing current application scenarios where computation faces privacy requirements. We then review existing cryptographic techniques for privacy-preserving computation. And last, we outline research problems that need to be solved for implementing privacy-preserving computations. Once addressed, privacypreserving computations can quickly become a reality enhancing the privacy protection of citizens.
