Preface

Privacy literature within the computer-science community has been mostly focused on responding to queries on large static datasets kept securely by a data curator. In practice, however, the underlying data in possession of the curator might change over time, sometimes according to a dynamical system. This has motivated a body of research on privacy in dynamical systems. This book attempts at presenting the state-of-the-art in this relatively new field of research. The contributions of this book focus on two distinct approaches for providing privacy. One approach is based on statistics. The authors in this case use randomness to ensure privacy and rely on information-theoretic measures of privacy or differential privacy. The other approach is based on using multi-party secure computation and homomorphic encryption for restricting access to private data. In what follows, I provide a brief summary of the contributions in this book. In Chap. 1, the authors propose a measure of privacy using the Fisher information. They particularly focus on smart meter privacy and use heating, ventilation, and air conditioning units for masking private information that can be extracted from the energy cons
