基于区块链技术的高校图书馆大数据存储方法设计

Design of Big Data Storage Method of University Library Based on Blockchain Technology

为提升高校图书馆大数据存储效果,降低数据丢包率,本文提出一种基于区块链技术的高校图书馆大数据存储方法。利用变更数据捕获(Change Data Capture,CDC)算法对待存储数据中的重复数据进行检测,并对重复数据进行删除,控制图书馆大数据冗余度;通过对图书馆数据所属法人身份和数据身份进行验证,检验其是否为合法数据;应用区块链技术对图书馆大数据进行加密处理,并在此基础上采用HBase技术对图书馆大数据进行多维排序映射存储。经实验证明,本文设计方法的丢包率较低,具有较好的可行性以及较强的可靠性。

In order to improve the big data storage effect of University Library and reduce the data packet loss rate,this paper proposes a big data storage method of University Library Based on blockchain technology.Use CDC algorithm to detect the duplicate data in the stored data,delete the duplicate data,and control the redundancy of big data in the library;Verify the legal person identity and data identity of the library data to check whether it is legal data;Apply blockchain technology to encrypt library big data,and on this basis,use HBase technology to store library big data in multi-dimensional sorting mapping.Experiments show that the design method has low packet loss rate and good feasibility and reliability.
