U.S. Immigration Police Bought Real-Time Ad Bidding Data for Automated Tracking System ⇥ 404media.co

Joseph Cox, 404 Media:

Customs and Border Protection (CBP) bought data from the online advertising ecosystem to track peoples’ precise movements over time, in a process that often involves siphoning data from ordinary apps like video games, dating services, and fitness trackers, according to an internal Department of Homeland Security (DHS) document obtained by 404 Media.

Although CBP described the move as a pilot, the DHS Office of the Inspector General (OIG) later found both CBP and ICE did not limit themselves to non-operational use. The OIG found that CBP, ICE, and the Secret Service all illegally used the smartphone location data, and found a CBP official used the data to track coworkers with no investigative purpose. CBP and ICE went on to repeatedly purchase access to location data.

There are people out there who will insist, to this day, that behaviourally targeted advertising is not actually a mechanism for surveillance despite all the evidence showing it is, in fact, an essential component.
