CarParker: A Blockchain-Based PrivacyPreserving and Accident-Proof-Preserving Private Parking Space Sharing System

EasyChair Preprint no. 395

Abstract

As sharing economy boomed recently, many applications or systems in this area have entered our lives. In this paper, we proposed CarParker, a novel blockchain-based parking space sharing system, by using which users who own vacated parking space can publish and share, while users who are looking for a parking lot could reserve online via our system. Incentives will be provided to the sharing parties, and the parking space user will be charged based on the rates and parking time. Our proposed service could relief the parking pressure in the downtown to some extent. However, this kind of service does also bring in some security and privacy issues. Since CarParker is blockchain-based and provides data provenance, each complete order and transaction between the user and the sharer along with images proof taken after parked and taken before leaving will be recorded in a tamper-proof manner. In the meanwhile, user ID verification mechanism results in various risks to user's privacy as malicious activities on these records cause severe damage to the users' reputation, finances, and so on. By implementing access control mechanism to those personal data, no third party including the data storage provider could access or utilise those data.
