Dynamic data masking

摘要

Described are methods and systems (202) for dynamic data masking (DDM) of sensitive data. The method for DDM comprises receiving a response output comprising sensitive data, based on a client request, from an application, and identifying a main masking specification, based on the response output, for masking of the sensitive data in the response output. Further, the response output is parsed for creating a Document Object Model (DOM) tree for the response output. Status of a masking approach indication field of the main masking specification is checked, and masking is performed on nodes in the DOM tree comprising the sensitive data, based on the status of the masking approach indication field of the main masking specification.
