However, since many envisioned applications and services require a user toconstantly reveal his locations, the user is in danger of loosing his location privacy.Hence, in the context of vehicular communication systems, a meaningful location pri-vacy metric is indispensable for the assessment of potential location privacy risk, thedevelopment of privacy-enhanced technologies, and the evaluation and benchmarking ofany given location privacy-protection mechanisms.Measuring a user’s location privacy is a non-trivial task.
