Private companies are tracking your location without notice or a warrant — and it's all perfectly legal,
And yes, they're handing your data over to law enforcement.
Bluetooth seems harmless enough. It connects your phone to your car stereo to play music or pairs your fitness tracker with your phone to relay data. But did you know Bluetooth hides a hidden danger that could expose your location? Even worse, private companies and law enforcement can use this exploit to monitor your activity without giving notice or obtaining a warrant.
Your phone tattles on you in public (even if you don’t know it) By its own admission, a marketing technology company called Leonardo US Cyber and Security Solutions revealed that it can use Bluetooth and WiFi to “identify people of interest by the signals emitted from their electronic devices they travel with” through a service called SignalTrace.
Its immense power can easily be abused to follow practically anyone.
All electronic devices emit signals that exchange data and information. Cellular data connects to local cellphone towers in the area. WiFi connects to the nearest router in a building. Bluetooth talks to other devices within the vicinity, just in case it needs to send or receive a message, a photo, or a song.
These technologies are especially precise these days. For instance, Bluetooth 6.0, the latest version of this protocol, features proximity-level location tracking that can pinpoint the position of a target device down to 10cm. At the same time, WiFi 7 includes indoor device positioning that can help identify the placement of a device inside buildings. Together, they offer powerful location-tracking capabilities that reveal where a device exists in real time.
i think the cell phone is the mark of the beast.........
