基于区块链的数据治理协同方法

针对当前数据治理过程中面临的数据标准不统一、数据质量良莠不齐以及数据安全隐私凸显等问题，提出一种基于区块链的数据治理协同方法，将区块链多方协作、安全可信等特性应用到数据标准的构建、数据安全的保障和数据共享过程的控制。本方法首先根据数据治理要求和区块链特征，提炼形成基于区块链的数据治理协同模型，通过构建多方协作的数据标准流程、数据标准构建和更新机制、安全可靠的数据共享和访问控制等，实现区块链数据治理协同方法，从而提升数据标准化工作的效率和安全性。实验及分析结果表明，该方法比传统的数据标准构建方法在标准用语申请时间效率上有明显的提升，特别是在大数据环境下，基于区块链智能合约的方法对时间效率提升更为明显，基于区块链的分布式存储等特性为系统的安全、用户行为追溯和审计提供了有力依据和保障。该方案对于数据治理工作具有良好的应用示范效果，为行业的元数据管理、数据标准的共享和应用提供了借鉴思路。

Data governance collaborative method based on blockchain

To solve the problem of inconsistent data standards, uneven data quality, and compromised data security privacy in current data governance process, a new blockchain-based data governance collaboration method which integrates the characteristics of multi-party cooperation, security and reliability of blockchain was proposed and applied to the construction of data standards, the protection of data security, and the control of data sharing processes. Based on data governance requirements and blockchain characteristics, a collaborative data governance model was formed. A multi-collaborative data standard process, an efficient data standard construction and update mechanism, and secure data sharing and access control were developed afterwards. So this blockchain-based data governance collaboration method could be implemented to improve the efficiency and security of data standardization work. The experimental and analysis results show that the proposed method has a significant improvement in the efficiency of the standard term application time than the traditional data standard construction method. Especially in the big data environment, the application of the smart contract improves the time efficiency. The distributed storage of the blockchain provides powerful basis and guarantee for system security, user behavior traceability and auditing. Methods mentioned above provide a good application demonstration for data governance and a reference for the industry's metadata management, data standards sharing and application.
