As the importance of vehicle data increases, it has become very important to safely store them. However, because onboard diagnostics scanners generally used to store vehicle data are IoT devices, security and capacity issues exist to store data safely and efficiently. To address this, we propose a system that stores vehicle data safely and efficiently using blockchain and IPFS. Users can access the system through DApp, an Ethereum-distributed application, and manage their vehicle data. Various experiments have been conducted to demonstrate the superior performance of this system, and the experimental results show its advantages in terms of data-processing speed and cost.

使用区块链和IPFS进行可靠的车辆数据存储

随着车辆数据重要性的增加，安全地存储它们已经变得非常重要。但是，由于通常用于存储车辆数据的车载诊断扫描仪是IoT设备，因此存在安全和容量问题，无法安全有效地存储数据。为了解决这个问题，我们提出了一种使用区块链和IPFS安全有效地存储车辆数据的系统。用户可以通过以太坊分布式应用程序DApp访问系统，并管理其车辆数据。已经进行了各种实验以证明该系统的优越性能，并且实验结果表明了其在数据处理速度和成本方面的优势。
