METHOD AND SYSTEM FOR DATA PATTERN MATCHING, MASKING AND REMOVAL OF SENSITIVE DATA

Systems, methods and computer-readable media for applying policy enforcement rules to sensitive data. An unstructured data repository for storing unstructured data is maintained. A structured data repository for storing structured data is maintained. Request for information is received. The request is analyzed to determine its context. Based on the context, a policy enforcement action associated with generating a response to the request is identified. The policy enforcement action may be to remove sensitive data in generating the response to the request and/or mask sensitive data in generating a response to the request. An initial response to the request is generated by retrieving unstructured data from the unstructured data repository. Using the structured data maintained in the structured data repository, sensitive data included within the initial response is identified. The policy enforcement action is applied to the sensitive data included within the initial response to generate the response to the request.
