Abstract:

In the past few years, online taxi-hailing services have gained acceptance as a convenient way to travel and are becoming increasing popular. However, privacy concerns come into being along with the online taxi-hailing service. Most of the existing privacy-preserving online taxi-hailing systems rely on a central third party to manage the whole system. This construction has three drawbacks. First, the online taxi-hailing platforms and the drivers can view the passenger's entire ride trajectory freely. Second, the platforms tend to prioritize matching orders with longer distances. Third, the platforms are vulnerable to a single point of failure attack. This article proposes a privacy-preserving ride-matching scheme without a trusted third-party server. In this article, we construct an efficient driver-passenger matching algorithm by using the public key encryption with equality test and blockchain with smart contracts, which efficiently match the ride request and ride offer in the encrypted form. Theoretical analysis shows that our scheme is feasible and practical. Experimental analysis provides reliable support for theoretical analysis.
