Title: “Personal Computation: Algorithms, Fundamental Limits, and Applications”

Abstract: We focus on Private Computation, a framework that enables users to evaluate functions over remotely stored data while concealing sensitive aspects of the request, including the computation being performed and the specific data items involved. We review several key information-theoretic privacy notions: functional privacy, which hides the coefficients of the requested linear combination; joint support privacy, which conceals the complete set of participating data items; and individual support privacy, which protects each data item independently. We conclude by discussing how Private Linear Computation (PLC) can serve as a fundamental primitive for enabling privacy-preserving statistical inference and machine learning over remotely stored data.
