Protecting privacy, civil rights and civil liberties using data labeling and segmentation

The Cyber Security Division of Department of Homeland Security (DHS) Science and Technology's Homeland Security Advanced Research Projects Agency is prototyping data labeling and data segmentation services that leverage dynamic fine-grained access control to protect information considered sensitive and/or related to privacy, civil rights, and civil liberties (P/CRCL). Prototype operationalizes significant work that has already been completed in the Information Sharing Environment (ISE) and the schemas and documentation available in National Information Exchange Model (NIEM) Information Exchange Package Documentation (IEPD) for Critical Infrastructure and Key Resources fusion center information sharing requirements. This paper describes three Unified Modeling Language (UML) use cases, concept of operations, and architecture for using dynamic fine-grained access control, data labeling, and data segmentation to anonymize, mask, or redact data that might be shared by a Fusion Center in accordance with organizational, jurisdictional, and Community of Interest (COI) laws, regulations, and policies.
