Abstract	Location information is exchanged among members of Vehicular Ad Hoc Networks (VANET) to serve many road and safety applications. Vehicles will announce their identity, position, and mobility information to their neighboring nodes. The importance of such information makes privacy a major concern. Successful implementation of VANET requires protecting the vehicle's identity at all times and preventing attackers from tracking vehicles and building traveling profiles of other users. The authorities, on the other hand, should be permitted to track certain subjects for non-repudiation and accountability purposes. Researchers have discussed privacy in VANET and have proposed different solutions to protect users' identities, such as using digital signatures. However, there is still a risk that profile building can be done by an attacker using a compromised vehicle. In this paper, we will describe the security threat and propose a solution to protect the user's privacy by eliminating the use of vehicle IDs in beacon messages and secure information handling.
