Protecting Vehicle Privacy Using Dummy Events

VANETs (Vehicular Ad Hoc Networks) can improve safety and enable a wide range of internet services, such as location based services. The problem is VANETs can also be used for tracking vehicles, raising privacy concerns. To confuse potential eavesdroppers some researchers have approached the problem by having network nodes transmit dummy data along with true data. Few such proposals consider vehicular applications where network nodes, vehicles, often travel along predictable paths, roadways. In this paper our approach is to examine one generic dummy-based scheme which we applied in a vehicular context. The results we found were that, with modifications, the scheme may be useful in certain vehicular situations.
