Abstract

The invention discloses a cross-department ocean data sharing method based on a block chain. The method comprises the steps of according to an agreement negotiated by multiple users, generating an intelligent contract, and determining a consensus node; via the consensus node, deploying the intelligent contract into a P2P network of the block chain; receiving a data processing request of any oceandata department, authenticating and checking data requested by the data request, and generating a sharing list, wherein the any ocean data department belongs to one of the multiple users; storing thesharing list into a block chain account and diffusing the same; performing whole-network consensus on the sharing list and spreading to the whole network, and generating an overall sharing list; and based on the overall sharing list, sharing the ocean data across the departments. According to the method provided by the invention, by using the distributed computing nodes and accounts based on the block chain, the problem of cross-department sharing feasibility and security of the mass data is mainly solved.

Description

technical field [0001] The invention belongs to the field of smart ocean technology, and in particular relates to a blockchain-based cross-department ocean data sharing method. Background technique [0002] The "Smart Ocean" project is an organic combination of "marine industrialization + marine informatization". It uses industrial big data and Internet big data technology to realize the sharing of marine resources and the coordination of marine activities, tap new needs, create new values, and achieve intelligent management of the ocean. the goal of. In the construction of the "smart ocean" project, a large amount of marine environment, target and activity data will be generated. It is the core value of the whole project to deeply mine these data to further form application service capabilities and realize the value-added circulation of data assets, and its prerequisite is the opening and sharing of massive data under the condition of protected ownership. [0003] Due to ...
