Abstract

In the future, cyber-physical systems (CPSs) will be used in most of real time scenarios. To make the world smart, the application of such systems is inevitable. However, with increasing use of such systems, privacy has also to be increased. If privacy aspect is compromised, then the users will not be easily habituated to such systems. CPSs involve multiple heterogeneous sensor data sources, so introducing considerable level of privacy remains an ever growing challenge for the system designers. In this chapter, we are going to present the applicability of exact penalty function and its benefits to increase the privacy level of CPSs. We will compare this with other techniques of privacy preservation in CPSs and throw light on the future enhancements of our proposed privacy framework.

7.1 Introduction

Cyber-physical systems (CPSs) are becoming an increasingly important component of modern life. One of the most well-known CPS operations, which span smart homes, smart transportation systems, smart energy systems, and smart ...
