  Abstract

The blockchain-based decentralized identifier(DID) for the automotive industry will be commercialized. However, because the DID provides not anonymity but pseudonymity, leakage of vehicle identifier, privacy threats related to driver-identifying information, vehicle’s location, vehicle’s driving information, communication message would be vital privacy issues. If an adversary collects transactions based on the same DID in the blockchain and reveled messages through wireless hacking, he or she can identify the vehicle and, track the vehicle’s location and driving information. In this paper, a privacy-preserving scheme for vehicles, which provides anonymity. It uses short-term DID for proof of ownership and for pseudonymous through unlinkability of blockchain transactions and communication messages. To verify the feasibility of the scheme, DID issue and verify procedures based on the DID standard are designed and implemented using Hyperledger indy blockchain, also, the results of basic performance analysis are described.
