The car-hailing platform based on Internet of Vehicles (IoV) technology greatly facilitates passengers’ daily car-hailing, enabling drivers to obtain orders more efficiently and obtain more significant benefits. However, to match the driver closest to the passenger, it is often necessary to process the location information of the passenger and driver, which poses a considerable threat to privacy disclosure to the passenger and driver. Targeting these issues, in this paper, by combining blockchain and Paillier homomorphic encryption algorithm, we design a secure blockchain-enabled IoV scheme with privacy protection for online car-hailing. In this scheme, firstly, we propose an encryption scheme based on the lattice. Thus, the location information of passengers and drivers is encrypted in this system. Secondly, by introducing Paillier homomorphic encryption algorithm, the location matching of passengers and drivers is carried out in the ciphertext state to protect their location privacy. At last, blockchain technology is used to record the transactions in online car-hailing, which can provide a security guarantee for passengers and drivers. And we further analyze the security and performance of this scheme. Compared with other schemes, the experimental results show that the proposed scheme can protect the user’s location privacy and have a better performance.
