Data Managing and Service Exchanging on IoT Service Platform Based on Blockchain with Smart Contract and Spatial Data Processing

초록

Expectation of cryptocurrencies has been increased rapidly and all of these cryptocurrencies are generated on blockchain platform. This means not only the paradigm is changing in the field of finance but also the blockchain platform is technically stable. Based on the stability of blockchain, many kind of crypto currencies or application platforms are being implemented or released and world famous banks are applying blockchain on their financial service[1]. Even law for exchanging cryptocurrencies is being discussed. Furthermore, blockchain platforms also run programmed source code which is called as smart contract on its distributed platform. Smart contract extends usage of blockchain platform. So in this paper, we propose an algorithm for recording and managing location data of IoT service provider and user based on blockchain with smart contract. Our proposal records data of participants in network by blockchain which ensures security and match with other optimized participant by spatial data processing.
