Summary:
This paper proposes a method of using a blockchain to solve the privacy problem and forgery of black box image data, which plays an essential role in determining the responsibility for traffic accidents and preventing accidents. Blockchain that can operate inside vehicle black box IoT or connected car is used, and for this purpose, the size is reduced for operation in low-power, low-capacity devices. By enabling consensus, security problems can be solved through a lightweight blockchain that can operate inside a black box device. As a result of the experiment, it was confirmed that the IPFS upload and download delay time increased linearly, and the proposed consensus algorithm decreased 63% compared to PBFT.
