Privacy Risk Evaluation of Human Mobility Data for Urban Transportation Planning

The purpose of this project is to contextualize privacy risk in the built environment and to place the resulting probabilities into a tool for public agencies. This project builds upon existing studies and addresses the problems by testing three hypotheses: 1. Linking human mobility data with built environment data increases the uniqueness of human mobility traces, thus increasing the privacy vulnerability of mobility datasets (i.e., probability of re-identification of individuals); 2. Due to the differences in travel patterns, privacy vulnerability is heterogeneous across built environments, categorized by urban density, land use mixture, and property value, and user groups, which may be categorized by age, gender, and amount of travel; 3. Built environment types require different approaches to preserve privacy (i.e. different levels of generalization and suppression) to optimize the tradeoffs between privacy protection and loss of information utility in transportation planning and operations.
