(note - this document was approved in late October (date shown on the cover of this document) - this is first time this NISTIR has been announced on CSRC website) NIST announces the final release of NIST Interagency Report (NISTIR) 8053, De-Identification of Personal Information. De-identification removes identifying information from a dataset so that individual data cannot be linked with specific individuals. De-identification can reduce the privacy risk associated with collecting, processing, archiving, distributing or publishing information. This document summarizes roughly two decades of de-identification research, discusses current practices, and presents opportunities for future research.
