HL7 has developed standards for segmenting sensitive data for HL7 v2 and CDA.  No such guidance is available for FHIR implementers.  This section of the Security WG Confluence site is intended to house current work in this area.

Please also see our pages on Security Labeling and CUI from a conceptual level, and the Cross-Paradigm US Security Label project for examples of what could be adopted as consensus approach for using security labels for CUI 32 CFR Part 2002, 42 CFR Part 2, and Title 38 Section 7332

Project Need

There is a need to develop FHIR implementation guidance for the use of FHIR labels to emulate the syntactical structure for security labeling as defined in the HL7 Healthcare Privacy and Security Classification System (HCS), which is the normative, conceptual model upon which both HL7 v2 and the Data Segmentation for Privacy CDA IG are based.  The syntactic structure of security labels dictates how the security tag sets (HL7 security labeling terminology) are used to populate specific fields in a security label with appropriate tags so as to represent a computable policy. 

In addition, there is a need for guidance and examples for how a community can develop consensus security labels for specific policies so as to minimize variance in policy representations so that rules engines are apply to uniformly enforce them to enable trusted exchange of health information among trading partners who ascribe to the same consensus labels.

Security Labeling Conceptual Guidance

The Security WG provides several pages devoted to providing detailed guidance on specific types of Security Tags and topics such as how to assign High-Water Marks to "wrappers" or enveloping structures used to transmit HL7 v2, CDA, and FHIR content.
