摘要
与传统的中心化信息系统相比,区块链具有防篡改、可跟踪和数据共享等优势。文章描述了联盟区块链Fabric的交易流程,并深入研究了其最新的细粒度数据保护机制——隐私数据集。文章采用Fabric区块链通道和隐私数据集相结合的方式,提出了在线教育资源联盟信息保护机制,设计了针对具体场景的实现策略,在实际区块链环境中验证了应用效果。最后,对在线教育资源联盟信息保护机制的发展和完善进行了讨论和展望。
Compared with the traditional centralized information system,blockchain has the advantages of tamper-proof,traceable and data sharing.This paper described the transaction process of the Fabric blockchain,which was the representative of the alliance blockchain,and made an in-depth study of its latest fine-grained data protection mechanism(privacy datasets).The core idea of information protection mechanism of online education resource alliance was put forward by combining Fabric blockchain channel and privacy datasets.The implementation method was designed for specific scenarios,and the application effect was verified in the actual blockchain environment.Finally,the development and improvement of the information protection mechanism of the online education resource alliance were discussed and prospected.
