The Digital Footprint Crackdown: How ICE Turns AI Into a Targeting Tool

Federal immigration enforcement is now a stack of systems that fuse data, automate searches, and surface targets faster than traditional investigative work.

Public records, federal inventories, contracts, and investigative reporting show U.S. Immigration and Customs Enforcement (ICE) leaning on a growing ecosystem of AI-enabled tools: large-scale analytics platforms, social media monitoring, facial recognition, and commercial location data products that can map people’s movements in granular detail.

A public window into ICE’s AI use

The Department of Homeland Security (DHS) now publishes a simplified AI “use case inventory” that includes entries for ICE as part of a government-wide push to document non-classified AI deployments. The inventory provides a high-level view of what categories of AI are in use, even when operational details remain limited.

That official snapshot is complemented by contracting data and independent investigations that describe how these systems can be used in practice: identity matching across databases, automated lead generation, and the ability to connect digital traces including faces, phones, vehicles, and online posts into a single investigative picture.

The “data plumbing”: ImmigrationOS and large-scale analytics

At the center of ICE’s modern enforcement technology is an analytics model sometimes described as “data plumbing”: software that lets investigators search across many datasets at once, link identities, and prioritize leads.

In 2025 reporting, WIRED detailed a $30 million contract for Palantir to build an “Immigration Lifecycle Operating System,” commonly referred to as ImmigrationOS, describing functions such as targeting/prioritization and tracking related to departures.

Civil liberties groups and immigration researchers argue that these integrated platforms can widen surveillance beyond a single suspect, because linking tools work by expanding the web of associated people, addresses, devices, and records. A Guardian investigation based on internal documents described Palantir’s long-running role embedding tools into ICE workflows and connecting disparate records into mobile, real-time investigative capabilities.

Social media monitoring scaled by automation

Another pillar is open-source intelligence (OSINT) gathered from social media. In October 2025, WIRED reported on ICE plans to build a 24/7 social media monitoring capability, an approach that typically relies on automated filtering and AI-assisted search to process high volumes of posts across multiple platforms.

Advocates warn that mass monitoring can capture constitutionally protected speech and association, especially when tools are tuned for “network discovery”, identifying communities and connections rather than investigating a single alleged crime.

Facial recognition moves into the field

Biometrics remain among the most controversial AI uses in law enforcement. DHS has publicly described its uses of face recognition/face capture and linked them to the department’s AI inventory.

In 2025, the EFF and ACLU highlighted concerns about “Mobile Fortify,” described as a smartphone-based tool used by ICE personnel for face recognition during encounters, raising alarms about error rates, due process, and limited public oversight.

Separately, contract reporting indicates ICE’s investigative arm has also sought access to external face-search tools. Policy trackers and spending records tie DHS/ICE procurement to Clearview AI, whose database and methods have drawn significant scrutiny in the U.S. and abroad.

Commercial location data and “ad tech” as an investigative feed

The sharpest recent shift may be the growing interest in commercial location data, often sourced from mobile advertising ecosystems.

On Jan. 25, 2026, WIRED reported that ICE issued a request for information explicitly referencing “ad tech” and “big data” tools for investigations, signaling an interest in products that can provide location and behavioral signals at scale.

This comes on top of prior documentation that DHS components (including ICE) have purchased access to location data products. A 2022 House Judiciary Committee document, along with civil liberties reporting, described ICE purchasing Venntel licenses, part of broader federal reliance on commercially sourced location data.

Civil liberties groups argue that buying sensitive data from brokers can function like “warrantless surveillance by purchase,” especially when the same information might otherwise require a court order.

Tracking phones at the neighborhood scale

Recent reporting has pushed location concerns from abstract to concrete.

In January 2026, 404 Media reported on ICE’s use of Penlink tools such as Webloc and Tangles, describing systems that can analyze and follow mobile device location patterns over areas as small as city blocks, powered by commercial data feeds.

These tools, critics say, risk sweeping in large numbers of people unconnected to any investigation, because neighborhood-scale queries are inherently broad.

License plate reader networks: vehicles as locators

Location tracking isn’t limited to phones. ICE has also been documented accessing large automated license plate reader (ALPR) databases.

In 2019, the ACLU released records indicating thousands of ICE agents had access to a Vigilant Solutions ALPR database, which can reconstruct vehicle movements using scans collected by law enforcement and other partners.

While ALPR searches are sometimes framed as vehicle-centric, privacy researchers note that cars often function as proxies for people—especially in immigration enforcement contexts where home and work routes can become actionable intelligence.

Oversight questions loom

Even as DHS publishes AI inventories, critics argue that transparency arrives after deployments have matured, and that accountability mechanisms can lag behind the pace of adoption. On the same day as WIRED’s report about ICE’s interest in ad-tech tools, Reuters reported broader controversy over immigration enforcement oversight and transparency measures, reflecting a political environment in which surveillance capabilities are expanding while public visibility remains contested. What emerges from the public record is less a single AI “tracker” than a system-of-systems: face scans, phones, vehicles, posts, and records, stitched together by software designed to find patterns and produce investigative leads at scale.
