Privacy-Preserving Technologies

Abstract

This chapter introduces privacy and data protection by design, and reviews privacy-enhancing techniques (PETs). Although privacy by design includes both technical and operational measures, the chapter focuses on the technical measures. First, it enumerates design strategies. Next, it considers privacy-enhancing techniques that directly address the hide strategy, but also aid in implementing the separate, control and enforce strategies. Specifically, it addresses PETs for: (1) identification, authentication and anonymity; (2) private communications; (3) privacy-preserving computations; (4) privacy in databases; and (5) discrimination prevention in data mining.
