Location privacy has been considered to be an important issue along with the advances of location technologies and the pervasive use of location based services. Although a variety of location privacy techniques have been developed, language-based techniques have rarely been used on privacy enforcement of location-based services. In this work, we propose a verification framework to enforce the privacy preservation of locations. The enforcement leverages reachability analysis of pushdown system to ensure that the service-specific data aggregation functions comply with the privacy property. The approach supports inter-procedural analysis and is more precise than existing work.
