YouTube's likeness detection tool raises creator biometric privacy concerns
YouTube expanded its "likeness detection" tool that flags deepfake videos using creators' faces, but the tool's terms reportedly allow Google to use biometric data to train AI models. YouTube stated it has never used such data for training and is reviewing the sign-up language, but said it will not change its underlying privacy policy.
What happened
YouTube expanded its 'likeness detection' tool, introduced in October 2025, to millions of creators in the YouTube Partner Program. The tool scans videos across YouTube to identify where a creator's face may have been altered or generated by artificial intelligence.
To use the tool, creators must upload a government ID and a biometric video of their face. YouTube tied the tool to Google's privacy policy, which states that public content, including biometric information, can be used 'to help train Google's AI models and build products and features.'
Reported impact
Experts told CNBC that the policy language leaves the door open for future misuse of creators' biometrics. Rights advocates warned that the current terms introduce significant risks for creators seeking to protect their likeness.
