| 摘 要： | 在海洋数据体量快速积累和数据技术迅猛发展的时代背景下，海洋数据高效管理和价值挖掘成了重点课题之一。文章结合密码学中非对称加密技术(同态加密)和区块链中智能合约技术，构建“双链并行结合智能合约”的地区海洋数据安全共享系统。该双链系统中，“海洋数据注册链”管理共享节点、“海洋数据匹配链”管理待匹配节点，通过智能合约自动执行供需双方的资源有偿共享。该系统既促进了不同地区间的海洋数据共享流转，又保护了资源供应方的合法控制权，实现了对链上流通海洋数据的有效管理与监控，是区块链技术与传统海洋资源调查数据库相结合的海洋资源创新产物，理论上解决了不同地区间海洋经济发展中的海洋基础数据共享问题。

| Abstract: | Under the background of the rapid accumulation of marine data volume and the rapid development of data technology, the efficient management and value mining of marine data has become one of the key topics. This paper has constructed a regional marine data sharing system, which combined asymmetric encryption technology and smart contract technology in blockchain. In this double-chain system, the marine-data-supply-chain includes the sharing nodes, and the marine-data-demand-chain includes the nodes to be matched. The system achieves decentralization, safe and efficient sharing, voluntary circulation of value, effective growth of marine data resources by smart contracts in blockchain, which not only promotes the sharing and circulation of marine data between different regions, but also protects the legal control rights of resource suppliers. This system is a combination between blockchain technology and traditional marine resources survey database and, will manage to solve the problem of data sharing in the development of marine economy in different regions theoretically. |
