Abstract
The Intelligent Transport System has made transportation more efficient. With available traffic information and 5G technology, cars can effectively transmit relevant information to other road users, such as congestion, environmental forecasting, and accidents. This information is vital to designing a fast and efficient means of transport. However, many people do not participate in the sharing of information, even depending on the possibility, because this means that a lot of personal information about the car and its owner must be provided. The information systems used so far could not solve these problems. However, in the case of vehicles authenticated in the blockchain, the personal data of the car owner will remain secret and will not be made public. Due to decentralization, trust is based on blockchain technology and not on personal and sensitive data. To this end, the research goal is to create a blockchain where ITS data can be safely stored. Since the registration data can be efficiently saved in the blockchain, a smart contract is created without any special knowledge of its use by the end user. A smart contract always requires a simple registration, which is recorded in the contract. The data specified in the contract are automatically saved in the blockchain, avoiding all “traditional” centralized data storage solutions, thereby increasing the safe storage of data.
