The HITRUST De-Identification Framework was developed to offer a solution to the challenges facing the industry regarding de-identification. Developed in collaboration with information security, and de-identification professionals; the HITRUST De-Identification Framework provides a consistent, managed methodology for the de-identification of data and the sharing of compliance and risk information amongst entities and their key stakeholders.

After review of multiple de-identification programs and methods, including those propounded by agencies in the United States, Canada, and the United Kingdom, the HITRUST De-Identification Working Group (DIWG) believed that no one method is appropriate for all organizations. Instead, the DIWG has identified twelve criteria for a successful de-identification program and methodology that can be scaled for use with any organization. These twelve characteristics are further divided into two general areas:

  1. The first set of characteristics represents those for the program and the administrative controls that an organization should have in place to govern de-identification.
  2. The second set represents how the organization can actually arrive at a de-identified data set, either on an ad hoc basis or by instituting a process that will deliver de-identified data sets.
