Immigration and Customs Enforcement (ICE) is using a new mobile phone app that can identify someone based on their fingerprints or face by simply pointing a smartphone camera at them, according to internal ICE emails viewed by 404 Media. The underlying system used for the facial recognition component of the app is ordinarily used when people enter or exit the U.S. Now, that system is being used inside the U.S. by ICE to identify people in the field.
The news highlights the Trump administration’s growing use of sophisticated technology for its mass deportation efforts and ICE’s enforcement of its arrest quotas. The document also shows how biometric systems built for one reason can be repurposed for another, a constant fear and critique from civil liberties proponents of facial recognition tools.
“Face recognition technology is notoriously unreliable, frequently generating false matches and resulting in a number of known wrongful arrests across the country. Immigration agents relying on this technology to try to identify people on the street is a recipe for disaster. Congress has never authorized DHS to use face recognition technology in this way, and the agency should shut this dangerous experiment down,” Nathan Freed Wessler, deputy director of the American Civil Liberties Union’s Speech, Privacy, and Technology Project, told 404 Media in an email.
“The Mobile Fortify App empowers users with real-time biometric identity verification capabilities utilizing contactless fingerprints and facial images captured by the camera on an ICE issued cell phone without a secondary collection device,” one of the emails, which was sent to all Enforcement and Removal Operations (ERO) personnel and seen by 404 Media, reads. ERO is the section of ICE specifically focused on deporting people.
The idea is for ICE to use this new tool to identify people whose identity ICE officers do not know. “This information can be used to identify unknown subjects in the field,” the email continues. “Officers are reminded that the fingerprint matching is currently the most accurate biometric indicator available in the application,” it adds, indicating that the fingerprint functionality is more accurate than the facial recognition component.
The emails also show the app has a “training range,” a feature that lets ICE officers practice capturing facial images and fingerprints in a “training non-live environment.”
A video posted to social media this month shows apparent ICE officers carefully pointing their phones at a protester in his vehicle, but it is not clear if the officers were taking ordinary photos or using this tool.
Broadly, facial recognition tools work by taking one image to be tested and comparing it to a database of other images. Clearview AI for example, a commercially available facial recognition tool which is used by law enforcement but which doesn’t appear to be related to this ICE tool, compares a photo to a massive database of peoples’ photos scraped from social media and the wider web.
