Recent revelations indicate that certain license plate surveillance systems equipped with advanced sensors can gather extensive data on motorists, surpassing earlier estimations.
A notable example is the SignalTrace system developed by defense contractor Leonardo, which enables existing license plate readers to capture unique identifiers from mobile phones, AirPods, and other Bluetooth-capable devices, as reported by 404Media.
This capability may empower law enforcement agencies not only to obtain a vehicle’s registration details but also to gather pertinent information about the driver and any passengers who possess connected devices.
SignalTrace also detects non-contact RFID devices, including air-pressure sensors, workplace IDs, and even pet microchips.
According to Leonardo’s website, “The data collected reveals which array of devices are traveling in tandem.”
During investigations, algorithms can pinpoint specific combinations of devices that exhibit predictable movement patterns over time. This unique constellation of devices—with corresponding timestamps and geolocations—constitutes an electronic fingerprint, facilitating the identification of suspects or witnesses.
In essence, Leonardo aggregates identifiers linked to devices and vehicle registration numbers, funnels them through an algorithm, and, if multiple devices coalesce, establishes a correlation between the device owners and the associated vehicle.
This data is subsequently archived at Leonardo’s Enterprise Operations Center for future use, ostensibly by law enforcement entities, as reported by InsideEVs. The Independent has sought comments from Leonardo for clarification.
Moreover, Leonardo asserts that its sensors can gather data independently of a license plate reader, making them applicable in various scenarios, including “off-road and non-traffic environments such as railway stations, event venues, and shopping complexes.”
According to the report, Leonardo primarily serves police forces, border security units, and other government organizations.
This sensor technology adds a new dimension to the ongoing discourse on whether Automatic License Plate Readers (ALPRs) constitute mass surveillance and pose a threat to public safety.
The Electronic Frontier Foundation has cautioned that extensive reservoirs of personal data will inevitably become attractive targets for cybercriminals.
“The utilization of ALPRs enables law enforcement to track the movements of every driver on the road, irrespective of any criminal associations, resulting in colossal databases teeming with sensitive information. Few agencies possess the resources, personnel, or expertise to protect their systems from rapidly evolving cybersecurity threats,” the foundation articulated in a recent report.
The organization cited an advisory from the Cybersecurity and Infrastructure Security Agency (CISA) indicating that a specific ALPR system had several security vulnerabilities that criminals could exploit.
“The bulletin identifies seven flaws in Motorola Solutions’ Vigilant ALPRs, including inadequate encryption and insufficiently safeguarded credentials,” the report stated.
Leonardo asserted in a press release that while their technology “captures device frequencies emitted into the air,” it does not “decrypt or capture the content or communications from the devices.”
Thus, while ICE agents may be unable to access your text messages, they will have comprehensive insights regarding your travel companions, residential details, vehicle usage, and potentially whether your pet is at home.
