Meta uses AI to analyze bone structure and height to detect underage users - expanding to 27 EU countries
What it really says
On May 5, 2026, Meta announced AI technology that scans photos and videos for visual cues like height and bone structure to estimate whether a user is under 13 years old. Meta explicitly states this is not facial recognition - the AI does not identify specific individuals but analyzes general visual characteristics. In addition to visual analysis, the AI scans entire profiles for contextual clues: birthday celebrations in photos, mentions of school grades in posts, comments, and bios. If a user is classified as likely underage, their account is deactivated. The user must then verify their age through Meta's age verification process to prevent account deletion. Simultaneously, Meta is expanding Teen Accounts to 27 EU countries and Brazil. Teen Accounts include automatic protections: private profiles, restricted contact options, daily usage limits, and a quiet mode that mutes notifications at night. The technology was previously deployed in the US, Australia, Canada, and the UK. Facebook in the EU and UK is expected to receive the technology starting June 2026.
Our assessment
Concerns are partially justified and require nuanced consideration. On the positive side: child protection online is a legitimate and urgent concern. Users under 13 should not be on these platforms per Meta's own terms of service and EU law (GDPR Art. 8). Meta is taking concrete technical steps rather than relying solely on self-reported age. However, analyzing bone structure and height from photos constitutes de facto biometric processing - even if Meta doesn't call it 'facial recognition.' The GDPR classifies biometric data as a special category of personal data (Art. 9), whose processing is fundamentally prohibited unless an exception applies. Meta likely relies on 'legitimate interest' or child protection exceptions, but the legal basis is contested. Additionally, accuracy is a concern: height and bone structure vary significantly between individuals, ethnic groups, and early or late-developing adolescents. Misclassifications are inevitable. The combination of visual analysis and profile scanning amounts to comprehensive algorithmic surveillance of all users - not just minors.
Relevance for Germany
Directly relevant for Germany and the EU. The expansion of Teen Accounts to all 27 EU countries affects millions of German teenagers and their parents. The GDPR sets high standards for processing biometric data - especially for minors. The German Data Protection Conference (DSK) has repeatedly emphasized that biometric age verification procedures are only permissible under strict conditions. The Hamburg Data Protection Authority has previously sanctioned Meta for data protection violations. It is likely that European data protection authorities will scrutinize this new AI analysis. At the same time, German politicians and the German Child Protection Association have been pushing for better youth protection online for years - creating a tension between data protection and child protection that will shape the German debate.
Fact check
The announcement is confirmed by Meta's own Newsroom blog post and numerous independent media reports from May 5, 2026. TechCrunch, Android Headlines, 9to5Mac, and Digital Trends report consistently about the technology. Meta itself describes the approach as 'not facial recognition,' which is critically questioned by 9to5Mac. The expansion to 27 EU countries is confirmed by US News, RTE, and The Munich Eye. Teen Account protections (private profiles, usage limits, quiet mode) come from Meta's official blog post. The primary source (Meta Newsroom) is directly available.
