摘要
国产化信息数据具有很高的利用价值和挖掘价值,很容易成为泄露窃取的对象,使得国产化信息数据安全问题越来越受到关注。在此背景下,设计一种基于可信区块链的国产化信息数据泄露溯源系统。基于设计需要,在借助MVC基础架构的基础上,将系统框架设计为三层,即数据层、功能单元层和显示层。根据溯源步骤,设计三个功能单元。信息数据泄露判定单元:依据流量数据实现泄露行为判定;信息泄露源头定位:依据可信区块链技术,将国产化信息数据分块处理并以此为依据,寻找信息泄露的源头;信息泄露路径追踪:以源头为起点,构建B-M树并转换为有向无环图形式,完成国产化信息数据泄露路径绘制。结果表明:基于可信区块链的溯源系统应用下,定位误差(1.27),路径重叠指数(9.82),时间消耗均为最值(42.27 s),说明所设计的系统功能表现更好,源头寻找更加准确,溯源效率更高。
Localized information data has high utilization value and mining value,and is easy to become the object of leakage and theft,which makes the security of localized information data more and more concerned.In this context,a localization information and data leakage traceability system based on trusted blockchain is designed.Based on the design needs and MVC infrastructure,the system framework is designed into three layers,namely data layer,functional unit layer and display layer.According to the traceability steps,three functional units are designed.Information and data leakage determination unit:to determine the leakage behavior according to the traffic data;Location of the source of information leakage:according to the trusted blockchain technology,the localization information data will be processed in blocks and based on this,to find the source of information leakage;Tracking of information leakage path:taking the source as the starting point,build a B-M tree and convert it into a directed acyclic graph to complete the mapping of localization information data leakage path.The results show that under the application of the traceability system based on the trusted blockchain,the location error(1.27),the path overlap index(9.82),and the time consumption are all the maximum values(42.27 s),indicating that the designed system performs better,the source search is more accurate,and the traceability efficiency is higher.
