DHS/USCIS/PIA-017 Microfilm Digitization Application System (MiDAS)

U.S. Citizenship and Immigration Services (USCIS) maintains millions of electronic immigration-related records that were created between 1893 and 1975. USCIS created the Microfilm Digitization Application System (MiDAS) to retain these historical records. MiDAS enables USCIS to search the historical records and provide records to government agencies and members of the public who request this information for mission-related and genealogy purposes. USCIS is updating this Privacy Impact Assessment (PIA) to discuss the privacy risks and mitigations associated with the collection, use, and maintenance of personally identifiable information (PII) provided by MiDAS’ functionalities.
