ICE Uses Tool To Find 'Derogatory' Speech Online
An anonymous reader quotes a report from 404 Media: Immigration and Customs Enforcement (ICE) has used a system called Giant Oak Search Technology (GOST) to help the agency scrutinize social media posts, determine if they are "derogatory" to the U.S., and then use that information as part of immigration enforcement, according to a new cache of documents reviewed by 404 Media. The documents peel back the curtain on a powerful system, both in a technological and a policy sense -- how information is processed and used to decide who is allowed to remain in the country and who is not. GOST's catchphrase included in one document is "We see the people behind the data." A GOST user guide included in the documents says GOST is "capable of providing behavioral based internet search capabilities." Screenshots show analysts can search the system with identifiers such as name, address, email address, and country of citizenship. After a search, GOST provides a "ranking" from zero to 100 on what it thinks is relevant to the user's specific mission. The documents further explain that an applicant's "potentially derogatory social media can be reviewed within the interface." After clicking on a specific person, analysts can review images collected from social media or elsewhere, and give them a "thumbs up" or "thumbs down." Analysts can also then review the target's social media profiles themselves too, and their "social graph," potentially showing who the system believes they are connected to. DHS has used GOST since 2014, according to a page of the user guide. In turn, ICE has paid Giant Oak Inc., the company behind the system, in excess of $10 million since 2017, according to public procurement records. A Giant Oak and DHS contract ended in August 2022, according to the records. Records also show Customs and Border Protection (CBP), the Drug Enforcement Administration (DEA), the State Department, the Air Force, and the Bureau of the Fiscal Service which is part of the U.S. Treasury have all paid for Giant Oak services over the last nearly ten years. The FOIA documents specifically discuss Giant Oak's use as part of an earlier 2016 pilot called the "HSI [Homeland Security Investigations] PATRIOT Social Media Pilot Program." For this, the program would "target potential overstay violators from particular visa issuance Posts located in countries of concern." "The government should not be using algorithms to scrutinize our social media posts and decide which of us is 'risky.' And agencies certainly shouldn't be buying this kind of black box technology in secret without any accountability. DHS needs to explain to the public how its systems determine whether someone is a 'risk' or not, and what happens to the people whose online posts are flagged by its algorithms," Patrick Toomey, Deputy Director of the ACLU's National Security Project, told 404 Media in an email. The documents come from a Freedom of Information Act (FOIA) lawsuit brought by both the ACLU and the ACLU of Northern California. Toomey from the ACLU then shared the documents with 404 Media.
