De-identification removes identifying information from a dataset so that the remaining data cannot be linked with specific individuals. Government agencies can use de-identification to reduce the privacy risk associated with collecting, processing, archiving, distributing or publishing government data. Previously NIST published NISTIR 8053, De-Identification of Personal Information, which provided a survey of de-identification and re-identification techniques. This document provides specific guidance to government agencies that wish to use de-identification.

In developing the draft Privacy Risk Management Framework, NIST sought the perspectives and experiences of de-identification  experts both inside and outside the US Government.

Future areas of work will focus on developing metrics and tests for de-identification software, as well as working with industry and academia to make algorithms that incorporate formal privacy guarantees usable for government de-identification activities. Collected input will be used to correct technical errors and expand areas that are unclear.
