Immigration and Customs Enforcement (ICE) is deploying a new mobile app, “Mobile Fortify,” to identify people in the field using facial recognition and contactless fingerprinting via a standard smartphone. Leaked internal emails reveal the app gives ICE’s Enforcement and Removal Operations (ERO) real-time biometric identification capabilities. The system leverages a Customs and Border Protection database originally designed to photograph travelers entering or exiting the U.S., repurposing it for domestic surveillance and enforcement. This expansion of surveillance power, part of the Trump administration’s aggressive deportation strategy, proceeds without explicit congressional authorization. Civil liberties advocates from the ACLU warn that the technology is notoriously unreliable, prone to false matches, and that using it for street-level identification is a “recipe for disaster” that risks wrongful arrests and erodes privacy.
