Exploring the Unnerving World of Surveillance Cameras
In the digital age, the use of Automated License Plate Reader (ALPR) cameras has become a common sight in public spaces across the United States. Benn Jordan, a tech enthusiast and investigator, has taken it upon himself to shed light on the history and usage of these cameras, and more importantly, to develop countermeasures against them.
Jordan's investigation reveals that ALPR cameras employ machine learning and AI for image segmentation and optical character recognition (OCR) to read license plates. These cameras not only capture the vehicle's license plate number but also catalog the make and model of the car and any bumper stickers, providing additional identification information. This raises concerns about privacy and surveillance in public spaces.
To combat this, Jordan has developed a unique solution. He has designed a transparent sticker that makes a license plate unreadable to ALPR cameras while still visible to human observers. This ingenious invention, when applied to a vehicle's license plate, can cause the ALPR system to read the license plate as an incorrect alphanumeric sequence or miss detecting it entirely.
Jordan's countermeasures don't stop at the sticker. He has built a computer vision system using a Raspberry Pi 5, a Halo AI board, and You Only Look Once (YOLO) recognition software. This system, which Jordan claims is more accurate than any system currently used by law enforcement for $250, is designed to outperform the Motorola ALPR for in-vehicle use, a closed hardware system that is less effective at reading license plates.
Jordan's work extends beyond the conventional methods used to confuse AI image processing systems, such as IR LEDs for security cameras. He uses yarn as a means to confuse these systems, a less common yet effective approach.
While Jordan's investigation and countermeasures aim to provide solutions for circumventing the surveillance capabilities of ALPR cameras, they also serve as a reminder of the potential dangers of unchecked surveillance. George Orwell's novel "1984" has been used by some entities as a guide for creating surveillance states, rather than as a cautionary tale.
In a world where technology continues to advance and surveillance becomes more pervasive, the work of individuals like Benn Jordan takes on increased importance. His innovations offer a glimmer of hope for those seeking to protect their privacy in the face of ever-evolving surveillance technologies.
