摘要: 当前大数据交互的不透明性以及数据文件访问形式的不合理性, 导致大数据存储存在存储延时长、 安全性较差的问题, 为此提出基于区块链的非结构化大数据动态安全存储技术。 构建多用户规则调度模型, 利用存储数据包生成独立的行向量与 n 阶矩阵, 基于列不满秩概率完成存储算法设计; 采用区块链非对称加密技术的公私钥, 实现透明与完整的数据交互, 对次要信息与数据访问形式实施记录。 引入分布式文件系统, 将其与Mongo DB 非关系型数据库有效结合, 从而使非结构化大数据得到安全存储。 仿真实验结果表明, 该方法不仅具有理想的存储速率, 而且使大数据的完整性得到了保证, 具有理想的有效性与实践性。

Abstract: At present, the opacity of big data interaction and the unreasonable access form of data files lead to the problems of long storage delay and poor security in big data storage. We propose a dynamic secure storage technology of unstructured big data based on block chain. The multi-user rule scheduling model is constructed, the independent row vector and n-order matrix are generated by using the stored data packet, and the storage algorithm is designed based on the probability of column dissatisfaction rank. The public and private keys of block chain asymmetric encryption technology is used to realize transparent and complete data interaction and record the secondary information and data access forms. The distributed file system is introduced, which is effectively combined with Mongo DB non-relational database, and the unstructured big data can be stored safely.The simulation results show that the proposed method has an ideal storage rate, and ensures the integrity of big data. It is effective and practical.

Key words: blockchain, unstructured big data, dynamic secure storage, distributed file system, non-relational database
