US Customs and Border Protection exploited the online advertising ecosystem to track people's movements by purchasing commercially available location data from apps. This surveillance technique bypasses traditional warrant requirements by leveraging data brokers who collect information from smartphone apps. The revelation highlights how government agencies can access sensitive location data without judicial oversight through the commercial data marketplace.
Background
Location data collected through mobile apps is often sold to data brokers who aggregate and resell it to various buyers, including government agencies. This creates a surveillance loophole where law enforcement can access detailed location information without obtaining warrants.
