ABSTRACT
This chapter gives a brief view into the expanding topic of privacy preservation for data exchange. It describes the enhanced challenges and relevance of privacy preservation topic with the rise of sixth generation (6G) technology-based applications and highlights that privacy topic can be a “do or die” subject for achieving a higher adoption among individuals and industry. Privacy preservation of data can help the two ends meet by keeping the utility of data while protecting the privacy of individual data subjects. Cultural awareness and government structures across the globe push adoption of privacy preservation technologies. 6G technologies make possible low latency applications like holographic telepresence. Homomorphic encryption is needed to operate on encrypted data for privacy preservation. Differential privacy is the most widely accepted mechanism for privacy preservation. Pseudonymization presents a unique method in practice since time is unknown to replace an original value with another value in a dataset.
