The MITRE Identification Scrubber Toolkit (MIST) is a suite of tools for deidentifying free-text documents containing personally identifiable information (PII). MIST helps you replace these PII either with obscuring fillers, such as [NAME], or with artificial, synthesized, but realistic English fillers. The transformed documents you create with this toolkit are more likely to meet the requirements of your organization for protecting privacy in documents you distribute.
