US Immigration Agents Are Using a Face Recognition App Without Proper Verification, Exposing Thousands to Unnecessary Scrutiny.
A face recognition app used by US immigration agents across the country is not designed to reliably identify individuals in public, despite being approved for use without thorough scrutiny of its privacy implications. According to records reviewed by Wired, the app, called Mobile Fortify, has been used over 100,000 times since its deployment in May 2025.
The app was launched by the Department of Homeland Security (DHS) as a tool to determine or verify the identities of individuals stopped or detained during federal operations. However, it does not actually "verify" identities but instead generates candidate matches based on similarity scores and adjustable thresholds.
This technology mobilizes facial capture hundreds of miles from the US border, allowing DHS to collect non-consensual face prints of people who may be US citizens or lawful permanent residents. The app is built by NEC Corporation of America, a Japanese multinational headquartered in Tokyo, which has developed matching algorithms that are prone to errors when used outside controlled settings.
Testing by federal scientists at the National Institute of Standards and Technology showed that face recognition accuracy drops sharply when images are taken outside controlled conditions, including for top-performing NEC models. Street photos taken by cell phones lack controls such as fixed cameras, cooperative subjects, neutral expressions, plain backgrounds, and uniform lighting, which makes them prone to errors.
In recent cases, federal agents have been seen using the app to scan the faces of people later confirmed to be US citizens or others who were observing or protesting enforcement activity. The system is designed to maintain capacity when image quality varies, which means it can produce false positives.
The use of Mobile Fortify has raised concerns about the erosion of civil liberties and privacy. DHS officials have suggested building a database to catalog people who protest or observe immigration enforcement, and some agents are using the app to target individuals based on accent, perceived ethnicity, or skin color.
Senator Ed Markey described this as "the stuff of nightmares" and warned that DHS has deployed an "arsenal of surveillance technologies" that it is using to monitor both citizens and non-citizens alike. The use of facial recognition technology sits at the center of a digital dragnet that has been created in the US over the past year, Markey said.
Legislators have introduced bills aimed at prohibiting ICE and CBP from using certain facial-recognition and biometric surveillance tools, citing real-world consequences to privacy, civil liberties, and civil rights.
