摘要：

The Internet of Things data capitalization method based on blockchain smart contract was used as a solution to the challenges when ascertaining data ownership, dealing with the inefficiency of quantification and value transfer of digital asset. The data's right was determined by transferring data ownership and control from the equipment manufacturers to the users, with the aid of digital fingerprints stored in the blockchain. The data reliability was ensured by storing the up-to-date device status and hash of the data into the blockchain, which was achieved by the full lifecycle management and digital signatures. A data trading platform without any third-party was established based on smart contract to guarantee the security of data sharing and accomplish the realization and migration of data's value. The quantitative analysis of attack probability and attack success rate shows that the technology of blockchain smart contract provides data tamper resistance and eliminates the trust crisis in data transaction processes. The proposed method realizes the capitalization of data in the Internet of Things initially and may help promote the data value migration and data sharing in the Internet of Things in future. © 2018, Zhejiang University Press.
