Practical Secure Transaction for Privacy-Preserving Ride-Hailing Services

Abstract

Ride-hailing service solves the issue of taking a taxi difficultly in rush hours. It is changing the way people travel and has had a rapid development in recent years. Since the service is offered over the Internet, there is a great deal of uncertainty about security and privacy. Focusing on the issue, we changed payment pattern of existing systems and designed a privacy protection ride-hailing scheme. E-cash was generated by a new partially blind signature protocol that achieves e-cash unforgeability and passenger privacy. Particularly, in the face of a service platform and a payment platform, a passenger is still anonymous. Additionally, a lightweight hash chain was constructed to keep e-cash divisible and reusable, which increases practicability of transaction systems. The analysis shows that the scheme has small communication and computation costs, and it can be effectively applied in the ride-hailing service with privacy protection.

Toward a Secure and Decentralized Blockchain-based Ride-Hailing Platform for Autonomous Vehicles

“…Cao et al in [9] address transactional privacy issues by proposing a protocol framework that allows for anonymous ride-hailing and payment for services. This system uses publickey cryptography, an online transportation network, and a third-party payment platform to achieve this.…”

A Critical Analysis on the Evolution in the E-Payment System, Secuiry Risk, Threats and Vulnerability

“…Cao and Zhu [24], have presented a privacy-preserving secure ecash transaction scheme for ride-hailing services. Additionally, the author introduced an authenticated hash chaining mechanism to keep e-payment divisible and reusable, which extends the flexibility of transaction systems.…”
