Abstract

Systems and methods for masking content of different types are described. The system may implement the method comprising receiving a request to mask input content that includes sensitive and non-sensitive data. The method also comprises parsing the input content to create a content specific structure (CSS) to organize the input content in a structured format. The CSS includes a plurality of CSS nodes. The method analyses each CSS node against a pre-defined privacy policy and identifies sensitivity of the each CSS node. The method also creates a generalized masking structure (GMS) by creating a GMS node corresponding to each CSS node. Each GMS node contains sensitivity information related to corresponding CSS node. Data represented by GMS is masked based upon the sensitivity information stored in it.
