The σ-calculus : a process calculus for privacy-preserving protocols in location-based service systems

Abstract

Sogenannte Mechanismen zum Präservieren von Standortdatenschutz (LPPM) benutzen unterschiedliche mathematische Ansätze, um in der Kommunikation mit Standortbezogenen Diensten persönliche Daten der Nutzer zu beschützen. Diese LPPM versprechen verschiedene Datenschutz-Garantien, die nicht per se vergleichbar sind. Wir schlagen den σ-Calculus vor, der ein Prozesskalkül zum Modellieren von LPPM und deren Datenschutzeigenschaften ist. Des Weiteren präsentieren wir das Model-Checking-Tool LP3Verif, das, basierend auf dem σ-Calculus, Standortdatenschutzeigenschaften von LPPM automatisch verifizieren kann.

Location privacy-preserving mechanisms (LPPM) use different computational approaches to protect personal data in queries to location-based services. These LPPMs give different privacy claims that are not per se comparable. We propose the σ-calculus, a process calculus to model LPPMs and their privacy guarantees. Furthermore, we present LP3Verif, which is a model checking tool to verify location privacy properties of LPPMs using the σ-calculus.
