A Secure Blockchain-based Data Trading

Abstract: With the rising usage of room related information, the interest for spatial enormous information sharing and exchanging is developing quickly, which advances the rise of spatial information market. Notwithstanding, in customary information markets, the two information purchasers and information dealers need to utilize a concentrated exchanging stage which may be deceptive. Blockchain is a decentralized dispersed information capacity innovation, which utilizes the detectability and unforgeability to affirm and record every exchange, can tackle the inconveniences of the unified information market, in any case, it likewise presents the issues of safety and security. To address this issue,in this paper,we propose a blockchain-based spatial information exchanging structure with Trusted Execution Environment to give a believed decentralized stage, including information stockpiling, information question, information estimating and security processing. In view of this structure, a spatial information exchanging show framework was carried out and its plausibility and security were checked.
