Researcher Bill Swearingen of SIXCYBER showed at DEF CON that a learned vehicle-wrap pattern called noRecognition can make Flock license plate readers and other vision systems miss a car even while the camera still records it. The demo used a wrapped 2009 Toyota Yaris; the footage showed the vehicle, but the detection software logged nothing.
The trick is not invisibility. The wrap does not stop the camera from seeing the car; it steers the model away from deciding the object is worth logging, alerting on, or cross-checking as a plate hit. That leaves a gap between what the video contains and what the automated record says happened.
For local agencies and vendors that rely on AI to decide what gets logged, this is a completeness problem as much as a detection problem. If the machine-side record is missing, an audit trail can look clean even when the roadway footage shows the vehicle passing through.
