Privacy in the Age of Smart Glasses: How to Detect Covert Wearables
At Alvarez Technology Group, we are constantly monitoring the intersection of emerging technology, cybersecurity, and digital privacy. As wearable technology continues to seamlessly blend into everyday fashion, the line between public observation and covert surveillance is rapidly disappearing.
Devices like Meta’s Ray-Ban smart glasses and Snap Spectacles look virtually indistinguishable from regular eyewear. Yet, they pack high-definition cameras and microphones capable of recording anyone, anywhere. With privacy concerns mounting over “surveillance voyeurism,” a new wave of digital countermeasures is emerging. Here is what you need to know about the new tech designed to catch smart glasses in the wild.
The Courtroom Fiasco: A High-Profile Wake-Up Call
To understand the disruptive potential of modern smart glasses, look no further than a recent incident in the legal system. In February 2026, Meta CEO Mark Zuckerberg arrived at a Los Angeles Superior Court to testify in a landmark civil trial regarding the impact of social media.
As Zuckerberg’s entourage made their way into the courtroom—a strictly regulated environment where unauthorized recording devices are banned—observers noted they were conspicuously wearing Meta Ray-Ban smart glasses. Judge Carolyn Kuhl immediately recognized the security threat. Halting the proceedings, the judge ordered the removal of the glasses and issued a stern warning that any recordings must be deleted under threat of contempt of court.
When the developers of this technology cannot bring their own devices into a courtroom without sparking a legal intervention, it highlights a critical question: how are everyday citizens and businesses supposed to protect their privacy?
Enter “Nearby Glasses”: A Digital Radar for Wearables
For the general public, a new technological countermeasure has emerged. Developed by sociologist and hobbyist coder Yves Jeanrenaud, Nearby Glasses is an Android application that acts as a digital radar for covert surveillance tech.
“I consider it to be a tiny part of resistance against surveillance tech,” Jeanrenaud explained upon the app’s release.
How the Technology Works
From an IT perspective, the app utilizes a clever workaround. Because smart glasses must connect to smartphones to process data and save videos, they constantly emit Bluetooth Low Energy (BLE) signals. Nearby Glasses works by continuously scanning these “advertising frames”—the tiny packets of data broadcast by the glasses—to look for specific manufacturer identifiers.
When the app detects a Bluetooth signature assigned to companies like Luxottica (the manufacturer of Meta Ray-Bans) or Snap, it sends a push notification to the user’s phone. The app even calculates an estimated distance, alerting the user that a camera-equipped wearable is within a 10 to 15-meter radius. (For Apple users, a similar iOS app called Nearby Lens has also recently launched.
The Impending Threat: Facial Recognition
The release of detection apps comes at a critical tipping point for wearable AI. Until now, the primary fear surrounding smart glasses has been unconsented video recording. However, the stakes are rising.
Recent industry reports indicate that Meta is actively developing an internal facial recognition feature dubbed “Name Tag.” Theoretically, this would allow a smart glasses wearer to look at a stranger, run their face through an AI assistant, and instantly pull up their publicly available information and social media profiles. In a world where your identity could be instantly scraped by a stranger’s sunglasses, detection apps are shifting from niche privacy tools to essential digital utilities.
An Imperfect Solution to a Growing Problem
As IT professionals, we must point out that this detection technology isn’t perfect. Because these apps scan for broad company identifiers, they can occasionally produce “false positives,” triggering alerts for other Bluetooth devices made by the same parent companies, such as VR headsets or smartwatches.
Furthermore, if these detection apps become widely adopted, tech giants could theoretically obscure or randomize their Bluetooth signals. This would inevitably kick off a perpetual cat-and-mouse game between wearable manufacturers and privacy advocates.
The ATG Takeaway
As the recent courtroom incident proved, society and the law are still struggling to establish clear boundaries for everyday, invisible cameras. Until comprehensive regulations are passed to govern covert AI wearables, apps like Nearby Glasses offer an interesting, albeit imperfect, line of defense.
