The automated toll-tax collection system (ATCS) is advantageous to facilitate traffic management at the toll plaza and to save fuel for vehicles. The most advanced application of the electronic toll collection (ETC) system is to collect the toll-tax amount (TA) at toll plazas of the national highways. The few existing TA collection systems suffer from data security, transparency, privacy, and data immutability as these are centralized systems. As the Blockchain is a decentralized, transparent, secure, and low-cost technology. However, this paper presents an intelligent transportation management system (I-TMS) using Blockchain. The proposed I-TMS shows the way of implementation of blockchain technology for vehicle data management in various applications of I-TMS. Herein, a framework of blockchain-enabled ATCS (BATCS) is provided as a blockchain-based I-TMS application to collect TAs without stopping vehicles while they pass the toll plaza. Smart contracts are used to authenticate vehicles' data and to collect TAs automatically. An efficient algorithm is presented for data verification and TA collection in this paper. This research work provides a secure, transparent, and privacy-preserving framework in the field of the ETC system. The significant contributions of the BATCS compared with the RFID-based system are less fuel consumption and time-saving for a vehicle. The proposed framework can enhance data security and user privacy in the intelligent decentralized ETC system. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Nowadays, vehicle theft has been increased drastically all over the world. The prevention of vehicle theft is essential to enhance vehicle security. A large number of vehicles have been stolen for the lack of essential foundation and administration of a secure platform. Several existing systems were developed to protect the vehicle from unauthorized access. But, they suffer from various limitations such as data security, the possibility of cybercriminals activities, leakage of personal information, and centralized System. We propose a vehicle theft detection framework using a decentralized and secure platform to increase the security level of the vehicle. Blockchain and smart contracts are used to provide the security of the stored data on the ledger and authenticate a genuine user automatically with greater accuracy. In this paper, we present 2-Step Authentication (2SA) and unauthorized access detection algorithms. The 2SA ensures the secure accessibility of the application by providing the randomly token chosen by the user. The proposed framework can provide vehicle security and owner's privacy. In this proposed framework, more than one person can drive the vehicle authorizing by the vehicle owner without hampering stored data in the vehicle device. [ABSTRACT FROM AUTHOR]
