【Abstract】Data assets trading can encourage owners to distribute data and achieve large-scale data aggregation to promote the development of the supply chain system. Blockchain is a promising platform for constructing a decentralized data marketplace. The data may face risks in the marketplace, such as illegal theft, malicious tampering, or illegal distribution in the transactions process. The data ownership confirmation in a blockchain-empowered marketplace has attracted much attention in recent years. However, challenges still remain, including maintaining data integrity, traceability of illegal data, and accountability. In this paper, we propose a new data ownership confirmation scheme (DOCS) in the transaction scenario of blockchain-empowered distributed data assets trading. It integrates smart contracts, data-embedding technology, and data fingerprint to realize ownership confirmation and protection of data assets in transactions. DOCS ensures reliable mapping between on-chain data ownership information and off-chain data entities, which assists with the accurate prosecution of the illegal distribution of data assets. We demonstrate that DOCS can have desirable security properties in multiple attack models.
