Industrial data asset management method and system based on block chain technology

Abstract

The invention is suitable for the technical field of block chains, and provides an industrial data asset management method and system based on a block chain technology, and the method comprises the steps: obtaining industrial data, and obtaining the importance level of the industrial data; the method comprises the following steps: decentralizing industrial data through a block chain, obtaining an industrial data decentralization result, obtaining data blocks, and obtaining hash values of the data blocks; acquiring node information, comparing the node information with a preset value, if the node information exceeds the preset value, determining the node as an available node, acquiring an available node score, and selecting the node according to the score; according to the method, data blocks are encrypted, data block encryption results are obtained, data block access permissions are obtained, the access permissions and access requests are compared, and specific data are controlled to be accessed, modified or managed according to comparison results, so that the problems that management cannot be performed in combination with a block chain, the security and confidentiality of industrial data assets are insufficient, and the security of the industrial data assets is poor are solved. And the accuracy of asset management cannot be ensured.
