SignalTrace Tracks Vehicles Using Device Signals

TL;DR. New surveillance technology SignalTrace can track vehicles by detecting nearby mobile devices, expanding existing police tracking capabilities. - The system utilizes passive sensors to identify Bluetooth, Wi-Fi, and other wireless signals from devices within vehicles. - SignalTrace intends to augment Flock's camera network, enabling vehicle tracking even without license plate visibility. - This technology raises significant privacy concerns about pervasive surveillance through personal electronic devices. - The firm claims data is encrypted and anonymized, but privacy advocates warn of potential misuse and data retention issues.

• SignalTrace technology can identify and track vehicles by passively detecting the unique signals from onboard mobile devices (Bluetooth, Wi-Fi).
• It works as an augmentation to existing Flock license plate reader (LPR) camera networks, allowing tracking where LPRs might fail.
• The system aims to link vehicles to their occupants via device signals, potentially creating a broad surveillance network.
• Significant privacy concerns arise from the ability to track individuals through their personal electronic devices without explicit consent.
• The company asserts data is encrypted and anonymized, but details on how this protects individual privacy remain vague.
