Multi-field grading processing method and device, equipment and medium

Abstract

The invention provides a multi-field grading processing method and device, equipment and a medium, and the method comprises the steps: carrying out the data element marking of a plurality of fields in a business data warehouse, so as to obtain a plurality of data elements; generating a data element relation graph according to the incidence relation among the plurality of data elements and the sensitive level grading strategy relation among the data elements with the incidence relation; obtaining a plurality of query fields in the target query request, and determining target sensitive levels of the plurality of query fields according to relationships of target data elements corresponding to the plurality of query fields in the data element relationship graph; and performing target processing on the plurality of query fields according to the target sensitive levels of the plurality of query fields. Therefore, the potential association among the plurality of query fields in the target query request can be accurately captured, and the target sensitivity level of each query field is flexibly determined according to the potential association so as to perform targeted processing on each query field, so that the sensitivity problem caused by field combination is solved, and the security of data is guaranteed.
