Abstract

In an approach, a processor receives a request of a document. A processor identifies a set of datasets comprising a sensitive dataset, the set of datasets being interrelated in accordance with a relational model. A processor extracts attribute values of the document. A processor determines that a set of one or more attribute values of the extracted attribute values is in the set of datasets, the set of attribute values being values of a set of attributes. A processor determines that one or more entities of the sensitive dataset can be identified based on relations of the relational model between the set of attributes, where at least part of attribute values of the one or more entities comprises sensitive information. A processor, responsive to determining that the one or more entities can be identified, masks at least part of the set of one or more attribute values in the document.
