Privacy in location-based services and their criticality based on usage context

Abstract

Location based services are an important trend for smart city services, mobility and navigation services, fitness apps and augmented reality applications. Because of the growing significance of location-based services, location privacy is an important aspect. Typical use cases are identified and investigated based on user perceptions of usefulness and intrusiveness. In addition criticality of services is evaluated taking the typical technical realization into account. In the context of this analysis the implication of privacy patterns is investigated. An overall criticality rating based on applied location privacy patterns is proposed and thoroughly discussed, while taking the decrease of usability into consideration.
