Immigration and Customs Enforcement (ICE) is surveying the commercial advertising technology market for tools capable of supplying location data and large-scale analytics to federal investigators, according to a recent Request for Information (RFI).
Framed as market research rather than a procurement, the RFI seeks information from companies offering “Ad Tech compliant and location data services” that could support criminal, civil, and administrative investigations across ICE’s mission set.
I strongly recommend against using bluetooth connectivity unless completely necessary. Bluetooth is used for tracking, monitoring and detection. It is very precise. Your position can be triangulated with it and tracked in real spacetime using hardware that costs literally less than $5 without any warrant, license or restriction.
I strongly recommend getting USB-C adapter for headphones and opting out of smart wearables which rely on bluetooth.
Same for WiFi.
Even on Android/iOS these functionalities have big, friendly on/off switches in the status bar dropdown, but people are lazy.
And GPS (edit: “Location” to be more precise), but it will be harder to convince people to not constantly use it.
GPS is receive only, there’s no way to track you for using GPS, it’s only when you look up the coordinates that your device calculates that you could be identified.
Can always use one of those fully offline old Garmin car GPS maps too.
