The greatest progress in resolving the crucial problem of location privacy in Vehicular Impromptu Networks (VANETs), to essential component of Intelligent Traffic Systems (ITS), using innovative block chain-based trust management methodology. VANETs' high inherent mobility has long presented security issues, especially when it comes to using Location-Based Services (LBS). The creative solution gives cars the ability to request LBS while protecting their personal data with a secure verification process. Vehicle privacy is protected via the creation of anonymous shrouding zones, and vehicle behaviour is controlled and governed by an advanced trust management algorithm. By using blockchain technology, the system's data security is strengthened even more, resulting in a strong, impenetrable architecture. Thorough testing has proven the system's resilience against a range of assaults based on trust models, proving its efficiency in protecting vehicle privacy. The outcomes of simulation demonstrate the practicality of the suggested method in actual VANET circumstances, pointing to the possibility of a new era in safe and private ITC systems.
