Advances in Privacy Preservation Technologies

The rapid development of information technology and the continuous evolution of new business paradigms and personalized services have promoted frequent cross-border, cross-system, and cross-ecosystem interactions of users’ data, increasing the retention of privacy information in different information systems and expanding the risk of privacy information leakage. Subsequently, privacy preservation has received more and more attention from the society, and scholars have also carried out extensive academic research to develop privacy preservation technologies for different scenarios. This chapter will sort out and summarize the research advances of privacy preservation technologies from the perspective of technology evolution, with the main focus on privacy protection technology, privacy desensitization technology, privacy preservation confrontation analysis, etc. This chapter shows the necessity of proposing privacy computing during the evolution of privacy preservation technology.
