This chapter reviews the existing location privacy-preserving mechanisms (LPPMs). There have been some survey papers discussing this topic. For example, Shokri et al. discuss LPPMs in two groups: obfuscation mechanisms and anonymization mechanisms. Our review of the literature reveals two further mechanisms, cryptographic mechanisms and shared information reduction mechanisms, creating four categories for existing LPPMs.
