Decentralized Privacy-Preserving Solution Through Blockchain Smart Contracts and Spatial Cloaking for Ride Sharing Application

This research addresses privacy concerns in traditional ride-sharing applications by proposing a decentralized solution leveraging blockchain technology and smart contracts, complemented by spatial cloaking techniques. Conventional ride-sharing platforms rely on centralized intermediaries, exposing user location data to potential breaches. Our approach enhances system resilience, reducing the risk of network-wide disruption in the event of an attack. Spatial cloaking within smart contracts conceals location data from unauthorized access, significantly improving privacy protection. Our findings show improved system security with a effective deployment cost of gas units and an effective transaction cost of gas units, leading to faster blockchain block hashing. This research offers a promising path towards decentralized ride-sharing, combining blockchain and spatial cloaking for enhanced user privacy while maintaining system efficiency and security.
