Meta's Hidden Face Recognition Feature Revealed in Smart Glasses Code

Meta's Hidden Face Recognition Feature Revealed

Meta has quietly introduced a face recognition capability within its smart glasses ecosystem, one that was previously described as under development. This technology, named "NameTag," is embedded in the Meta AI companion app downloaded by over 50 million users and is essential for using features of Ray-Ban and Oakley smart glasses.

"The feature is not yet exposed to consumers but seems nearly ready to go," said Cooper Quintin, a security researcher with the Electronic Frontier Foundation's Threat Lab.

The discovery was made through a detailed code review conducted by WIRED, which found that core components of the NameTag system were already in place in software updates distributed throughout 2026. This contradicts Meta's public statements indicating it was still considering such features carefully.

Historical Context: A Pattern of Face Recognition

Meta has a history with face recognition technology dating back to Facebook's early days. The company introduced a system in 2010 that automatically suggested tags for faces in photos. This system grew to include more than a billion users and faced significant scrutiny from regulators and privacy advocates.

In 2021, Meta announced it would shut down its face recognition system and delete the biometric data collected. However, this move wasn't a permanent withdrawal. Internal documents reviewed by The New York Times in February 2025 showed that Meta was still planning to deploy facial recognition in smart glasses.

What NameTag Does

NameTag is designed to identify people using biometric data stored on users' phones. When activated, it would capture faces through the smart glasses and compare them to faceprints stored locally on the device. Recognized individuals trigger a notification, while others are cropped and saved for potential future use.

• One AI model detects faces
• A second crops faces for processing
• The third encodes them into unique biometric signatures (faceprints)

These models have already been deployed from Meta's servers to customer devices. Though the user interface is minimal, the system appears nearly complete.

Privacy Concerns and Legal Implications

Meta's renewed interest in facial recognition comes amid increased scrutiny of such technologies. Advocacy groups including the ACLU have called for the removal of NameTag, citing risks to personal safety and privacy. The feature could allow stalkers or abusers to silently identify strangers in public.

Privacy experts argue that embedding this kind of technology into mass-market wearables normalizes surveillance capabilities previously deemed too risky. Woodrow Hartzog, a Boston University law professor, notes that even opt-in consent mechanisms may not protect users effectively due to the psychological normalization of such technologies.

Meta's Public Stance

Meta's official response was cautious but defensive. Ryan Daniels, a Meta spokesperson, stated, "Nothing has shipped to consumers and no final decision has been made on what to do here." However, the presence of NameTag in the live app suggests that the company had already begun preparing for deployment.

The company emphasized it would take a "thoughtful approach" if it decided to proceed, though there's currently no clear indication of when or how this might happen. The system is designed to store faceprints locally rather than send data back to Meta's servers, but the implications remain concerning.

Technical Analysis and Security Insights

Independent researchers were able to reproduce parts of WIRED's analysis. Cooper Quintin from the Electronic Frontier Foundation and Buchodi, an independent security researcher, both confirmed that core elements of NameTag are present in the app. One test using a faceprint of Michel Foucault resulted in a recognition notification—demonstrating the system's readiness.

"Not many pieces stand between this and a working feature," said Buchodi, who noted the ease with which such a system could be operationalized.

The Future of Face Recognition at Meta

Meta's journey with facial recognition reflects broader industry trends. While some companies have moved away from such systems due to privacy concerns, Meta appears intent on re-introducing them—albeit in a more controlled environment. The potential for NameTag to be integrated into assistive technologies for the visually impaired may offer a path forward, but it also opens new ethical and legal questions.

Meta's decision to include face recognition in its smart glasses platform could shape consumer expectations and influence regulatory policies moving forward. As Meta continues to develop this technology, public and legal oversight will be critical in determining whether its deployment aligns with user privacy rights.
