ABSTRACTTraditional location tracking and positioning systems rely on the implicit assumption that users are willing to reveal their credentials or private location to an untrustworthy service provider; if a situation suddenly deteriorates, personal information can be intercepted and abused by adversary attacks. Addressing the need for location privacy is essential to preserve users’ credentials when they need to access location information from their service providers. Therefore, this review paper will address the phases of authentication and the querying process in location-based services (LBS). The first contribution is to rigorously investigate the mechanisms of location-based authentication and location-based personal identification in order to determine the level of trust for deciding whether traditional methods have provided a strong enough security structure to preserve privacy. The second contribution is to resolve the above privacy problems in the existing LBS systems. The idea of early interven...
