Privacy Preserving in the Modern Era

Abstract

The development of data communication technologies promotes large-scale sensitive data collection and transmission in various application areas. The sensitivity and criticism of the exchanged data raise several privacy issues. A lack of privacy may cause moral and emotional damage and discrimination. It can even create an unequal society. To fill this gap, a better understanding of privacy concept and its requirements is required. This chapter presents a comprehensive survey of privacy-preserving in the modern era. It deals with this concept of privacy-preserving from all perspectives, classifying its requirements into content-oriented and context-oriented ones. Based on the taxonomy, privacy attacks are described, and approaches and mechanisms for privacy protection are reviewed. A future research direction about privacy preserving in various fields is finally exposed.
