Data security acquisition method and system based on big data

The invention provides a data security acquisition method and system based on big data. Data information is acquired from a data source through a big data method, the data information is primarily processed, a data security monitoring table is established, a data link is established, data link node security information is acquired, and a data security value is calculated. Analyzing and acquiring a data danger track according to the first safety value, distributing a storage position of a collected incremental data link node according to the data danger track, and calculating a collection frequency adjustment value; the data acquisition frequency is adjusted, after adjustment is completed, whether the safety value is qualified or not is judged, big data safety monitoring and control can be achieved, and the integrity and safety of data are ensured. 本发明提出了一种基于大数据的数据安全采集方法及系统，通过大数据方法从数据源中获取数据信息，对数据信息进行初步处理，建立数据安全监测表，建立数据链，获取数据链节点安全信息，计算数据安全值；根据第一安全值分析获取数据危险轨迹，根据数据危险轨迹分配采集的增量数据链节点的存储位置，计算采集频率调节值；对数据采集频率进行调节，在调节完成
