Abstract
An apparatus for providing anonymity in geographic data for probe devices in a geographic region for a location-based service includes at least a database and a triangulation calculator. The database is configured to store trajectory data based on sequences of sensor measurements of the probe devices. The triangulation calculator is configured to calculate triangles from the trajectory data. Each of the triangles is defined by vertices. The triangulation calculator is configured to calculate a similarity score for the vertices based on trajectory data associated with adjacent vertices. At least one vertex is modified in response to the similarity score.
