The addition of complementary technologies multiplies the risk. SignalTrace, marketed by Leonardo US Cyber and Security Solutions (the American arm of Italian aerospace and defense giant Leonardo S.p.A., which is majority-owned by the Italian government), is designed to clip onto existing ALPR poles and hardware—including infrastructure already used by Flock customers. SignalTrace passively captures Bluetooth, Wi-Fi, RFID, and other wireless signals emitted by phones, smartwatches, earbuds, vehicle systems, and even pet microchips. It builds what the company calls an “electronic fingerprint” of devices that travel together, allowing law enforcement to track individuals even when a plate is obscured, swapped, or unreadable.

Flock has stated it has no contractual relationship with SignalTrace. That claim is narrowly true but incomplete: once the sensors are attached to the same poles and the data streams are available to the same agencies, the practical distinction collapses. Data retention policies for SignalTrace appear less restrictive than some of Flock’s stated limits, raising the possibility of longer-term archival for future queries.
