DHS Privacy Assessment Details Secret Service HELIX Surveillance Platform

The U.S. Department of Homeland Security has published a privacy assessment of the Secret Service’s HELIX platform, detailing how it combines surveillance video, facial recognition and license plate information around protected locations.

HELIX supports security at sites including the White House complex, the area surrounding the U.S. Capitol and the Naval Observatory. It brings video from fixed and mobile cameras into a common environment and can associate footage with facial images, biometric templates, vehicle plates, timestamps and location metadata.

The facial recognition function does not continuously search every recorded face against a general population database. According to the assessment, Secret Service personnel manually upload images of people designated as persons of interest by the agency’s Protective Intelligence and Assessment Division. HELIX then searches supported camera feeds for potential matches.

The cameras can capture public streets, sidewalks, parks and building entrances adjacent to protected sites. That coverage means people with no connection to an investigation may appear in the system while moving through public areas.

DHS identified risks including false facial matches, expanded tracking of individuals and limited opportunities for people to learn that their data was collected or seek correction. The assessment says activity is logged and access is restricted according to role, giving the Secret Service a record of searches and other user actions.

HELIX modernizes and integrates capabilities that existed in earlier Secret Service camera systems. The agency previously tested facial recognition around the White House, initially using watchlists tied to protective investigations rather than general criminal identification.

The disclosure arrives as DHS expands biometric tools across its components. Departmental planning has also described facial recognition services for state and local law enforcement, raising similar questions about watchlist scope, audit controls and the handling of non-matches.
