The Department of Homeland Security is expanding its AI use for FOIA processing in response to a sizable backlog and increasing number of requests, per the agency’s annual report. The influx of AI in FOIA processes has raised concerns among experts who point to the potential for degraded transparency and accountability. Per its use case inventory, DHS plans to tap the technology to “streamline the identification and redaction of sensitive content in documents related to FOIA requests.” While not listed in the itemized inventory, DHS mentions an AI platform, called RelativityOne, in its consolidated “Common Commercial AI Inventory.” A privacy threshold analysis approved by the DHS Privacy Office in 2024, however, identifies the document review software as a tool used to “timely respond to [FOIA] requests.”
