Problems solved by technology

But the focus of these methods is to find the ins and outs of the data, without paying too much attention to the "changes" in it, and these changes are often an important basis for error troubleshooting and understanding the details of data changes

Abstract

The invention discloses a method and a device for realizing data traceability, and relates to the field of big data information security. The method comprises the following steps: setting identification information in metadata pair data and each field in the data; when a field operation or a data operation is executed, adding operation information, source data information, derivative data information and a state identifier for each field in the metadata; according to the operation information, the source data information, the derivative data information and the state identifier of each field in the metadata, obtaining each source data of the current data and the operation of each source data influencing the current data by querying the data identifier information and the field identifier information; and taking the obtained source data as current data, and if the current data is not the initial source data, repeatedly executing the step of obtaining the source data of the current data and the operation of influencing the current data by the source data. The integrity and accuracy of data traceability are improved.

Description

technical field [0001] The present disclosure relates to the field of big data information security, and in particular to a method and device for realizing data traceability. Background technique [0002] Data traceability is a description of the original data and evolution process before the target data is derived. In the era of big data, massive data and the need for data mining and analysis, most of the data actually used are derived data after multiple data processing. When using data, it is often necessary to trace the source of the data, confirm the exact meaning of the data, calculate the data, and troubleshoot errors. [0003] At present, data traceability includes labeling method, reverse query method, two-way pointer tracing method, etc. At the same time, Apache Atlas launched by Hortonworks and Navigator launched by Cloudera all provide data traceability capabilities. But the focus of these methods is to find the ins and outs of the data, without paying too much...
