A decentralized vehicle anti-theft system using Blockchain and smart contracts

In recent years, vehicle theft has been increasing remarkably. It is a stigma to our society. The impacts of vehicle theft have been drastically affecting the social safety and economic condition of the whole world because of unavailability of a proper theft detection mechanism. The few existing vehicle anti-theft systems suffer from major problems such as the leakage of personal information, centralized-based system, proper key management, and data security. In this paper, a decentralized Blockchain-based Vehicle Anti-Theft System (BVATS) is proposed to overcome these problems using smart contracts. Blockchain is a very cutting-edge decentralized technology that is well-equipped with data immutability and a secure information-sharing platform. The smart contract is a digital agreement, which can authenticate an entity automatically and stores information by verifying the predefined condition(s). This paper also explains how Blockchain can be adopted for vehicle security and provides a stepwise implementation of the proposed methodology by providing test bed results and significant critical comparison analysis with other existing systems. Using the BVATS, more than one person can be authorized to drive a vehicle without hampering the vehicle data and maintining security.
