DHS/ALL/PIA-027 Watchlist Service

DHS receives a copy of the Terrorist Screening Database (TSDB), the U.S. Government’s consolidated database maintained by the Department of Justice (DOJ) Federal Bureau of Investigation (FBI) Terrorist Screening Center (TSC), to facilitate DHS mission-related functions, such as counterterrorism, law enforcement, border security, and inspection activities. In July 2010, DHS launched an improved method of transmitting TSDB data from TSC to DHS through a service called the DHS Watchlist Service (WLS). WLS maintains a synchronized copy of the TSDB, which contains personally identifiable information (PII) and disseminates TSDB records it receives to authorized DHS Components. DHS is updating this Privacy Impact Assessment (PIA) to add the United States Citizenship and Immigration Services (USCIS) Fraud Detection and National Security-Data System (FDNS-DS) as an authorized recipient of TSDB data via the WLS.
