Records reveal the scale of Homeland Security’s phone location data purchases

Investigators raised alarm bells once they discovered Homeland Safety bureaus have been shopping for telephone location information to successfully bypass the Fourth Modification requirement for a search warrant, and now it is clearer simply how intensive these purchases have been. TechCrunch notes the American Civil Liberties Union has obtained information linking Customs and Border Safety, Immigration and Customs Enforcement and different DHS divisions to purchases of roughly 336,000 telephone location factors from the information dealer Venntel. The data represents only a “small subset” of uncooked information from the southwestern US, and features a burst of 113,654 factors collected over simply three days in 2018.

The dataset, delivered via a Freedom of Data Act request, additionally outlines the businesses’ makes an attempt to justify the majority information purchases. Officers maintained that customers voluntarily supplied the information, and that it included no personally figuring out data. As TechCrunch explains, although, that is not essentially correct. Cellphone house owners aren’t essentially conscious they opted in to location sharing, and sure did not notice the federal government was shopping for that information. Furthermore, the information was nonetheless tied to particular units — it would not have been tough for brokers to hyperlink positions to people.

Some Homeland Safety employees expressed inner issues concerning the location information.

At one level, the division even halted all tasks utilizing Venntel information after studying that key authorized and privateness questions had gone unanswered.

Extra particulars could possibly be forthcoming, as Homeland Safety remains to be anticipated to offer extra paperwork in response to the FOIA request. We have requested Homeland Safety and Venntel for remark. Nonetheless, the ACLU report would possibly gasoline legislative efforts to ban these sorts of knowledge purchases, together with the Senate’s bipartisan Fourth Modification is Not For Sale Act in addition to the extra lately launched Well being and Location Information Safety Act.
