Meta's AI Now Scans Your Bone Structure to Catch Underage Users on Instagram and Facebook

Your selfie just became a medical exam. Meta is rolling out AI that scans height and bone structure in photos and videos to estimate user age on Instagram and Facebook.

Meta's AI bone structure analysis for age detection

The company announced it is now using AI visual analysis to scan photos and videos on Instagram and Facebook for physical indicators of age, including height and bone structure. The goal: find and remove accounts belonging to users under 13 who signed up with a false birthday.

Meta has been careful to clarify this is not facial recognition. The AI doesn't identify who someone is. Instead, it scans for general visual cues that suggest someone is young, like physical proportions, to estimate a broad age range. The visual scan works alongside existing text-based detection that catches birthday mentions and school grade references.

Why Meta is scanning bones right now

The timing here is anything but coincidental. This announcement comes weeks after a New Mexico jury ordered Meta to pay $375 million in civil penalties for misleading consumers about the safety of its platforms. Last week, the European Commission flagged that Meta may be breaching the Digital Services Act by failing to enforce the minimum age of 13 on Instagram and Facebook.

Meta is also expanding protections for suspected age misrepresentation on Instagram in the EU and Brazil, and Facebook in the US. Flagged accounts will be deactivated, requiring age verification to avoid permanent deletion.

Privacy concerns around AI bone scanning

Privacy advocates worry this represents another step toward comprehensive image scanning, even though Meta insists the analysis focuses on developmental markers rather than personal identification. False positives could lock out legitimate users who look younger than their age.

Here's the core tension: according to Internet Matters, 46% of children believe age checks are easy to bypass, while only 17% say it is difficult. Some kids even draw facial hair on themselves to fool systems. Bone structure analysis is harder to game than a birthday field. But social media photos aren't clinical X-rays.

Meta between courtrooms and regulators

Meta acknowledges that no single company can solve this challenge alone, and continues to advocate for app store-level age verification. Google publicly criticized that approach back in 2025. The real question: can you protect minors at scale without turning every platform into a radiology department?
