New License Plate Cameras Might Start Tracking Your iPhone

Those automatic license plate readers you see at intersections are getting a major upgrade, and it involves the gadgets right in your pocket. A new surveillance tool could soon allow law enforcement to link your car to your personal electronics. This means cameras will not just record your vehicle, but they will also log the wireless signals coming from any Apple products or smart devices you carry with you every day.



How sensors pair your car with the gadgets you carry



A defense contractor named Leonardo US Cyber and Security Solutions is offering a technology called SignalTrace. The system adds new sensors to existing automatic license plate readers. Instead of just taking a photo of a car, it actively scans for Bluetooth and Wi-Fi signals in the area.



When you drive by, the system picks up the unique hardware codes broadcasted by your iPhone and other nearby electronics. It can easily detect smaller wearable accessories, meaning even an Apple Watch will ping the system as you pass through an intersection.



The software then matches these device signals to the license plate captured by the camera. Leonardo states its software does not read your text messages or access your personal files. It simply collects the unique frequency identifiers to create a digital fingerprint of the people traveling inside the vehicle.



Why police want this data and the privacy risks involved



Police and border security agencies are the main customers for this technology. By collecting this data over time, algorithms can map out travel patterns and figure out if certain people are consistently riding together. For example, if the system logs the same set of AirPods traveling alongside a specific car multiple times, law enforcement can build a database of associates and track where groups are heading.



Privacy advocates are raising alarms about this level of tracking. Since the system just collects signals broadcasted in public spaces, police do not currently need a warrant to gather the information. If you keep a gym bag in the trunk with an AirTag inside, authorities can track that signal without your permission.



Civil liberties groups argue that storing massive amounts of location data on regular citizens creates a giant target for hackers. If a private contractor ever suffers a data breach, its database could expose the daily movements of millions of people.



The rules around digital privacy are struggling to keep pace with how fast this hardware evolves. For now, simply driving down the street might mean handing over a silent digital map of your life to anyone watching the intersection.
