As a representative example for the construction of a smart city, a smart parking system has been developed in past research and implemented through IoT and cloud technologies. However, the initial installation cost of IoT sensor devices is preventing the spread of this technology, and thus as an alternative, a crowdsensing-based system, operating through data from publicly owned mobile devices, has been proposed. In this paper, we propose a multi-blockchain structure (i.e., constructed with public chain and private chain) in a crowdsensing-based smart parking system. In this structure, many sensing data contributors participate through the opened public blockchain, to transparently provide sensing information and to claim corresponding rewards. The private blockchain provides an environment for sharing the collected information among service providers in real time and for providing parking information to users. The bridge node performs an information relay role between the two blockchains. Performance analysis and security analysis on the implemented proposed system show the feasibility of our proposed system. View Full-Text
