Meta is deploying a visual analysis system that uses AI to assess users' height and bone structure to determine if they are underage, now operating in select countries with a broader rollout planned. The approach sidesteps traditional age verification methods (ID upload, self-declaration) by using biometric inference. Raises significant privacy and accuracy concerns — false positives could lock out legitimate adult users, while the biometric data itself becomes a liability.
