AbstractThe advent of Location-based Services (LBS), especially in wireless communications systems, has raised a growing concern for user about his privacy. As for every location-based query, the user has to reveal his location coordinates (through technologies like Global Positioning Systems); if this information could be revealed to anybody, it becomes a privacy breach. To take care of these issues, several techniques have come up among which k-anonymity has been most widely used and studied in different forms and different contexts. In this paper, we have reviewed the application of k-anonymity for LBS and its recent advancements. While doing so, we have recognized three perspectives for the applicability of k-anonymity for LBS: the application of k-anonymity based on the architecture, based on the algorithms for anonymization, and based on the types of k-anonymity (according to the different query processing techniques). Hence, the review has been done within the framework of these perspectives. These...
