Blockchain Technology as a Defense Mechanism Against Data Tampering in Smart Vehicle Systems

Smart vehicle systems, integrated with cutting-edge technology, have evolved to become a crucial element of modern transportation. They are leading us into a fresh era of mobility, offering the potential for increased efficiency, upgraded safety, and enhanced user satisfaction. According to a study by Statista, in terms of IoT-related revenue, the automotive IoT market is expected to reach 23.6 billion US dollars in 2025 [1]. However, their reliance on data-driven technologies also exposes them to the ever-present threat of data tampering. In response to these emerging threats, the imperative to fortify the cybersecurity posture of smart vehicles has never been more pressing. Known for its decentralized, immutable, and transparent nature, blockchain is a promising solution for safeguarding critical vehicle data. As part of this research paper, we look at the fundamentals of blockchain technology and discuss how this technology can be used within smart vehicles to enhance the security and integrity of data generated, stored, and shared. By leveraging the blockchain's security features, stakeholders in the automotive industry can pave the way for safer and more reliable smart vehicle technologies. This research also invites further exploration and collaboration to harness the full potential of blockchain in fortifying the future of smart transportation.
