Anthropic introduced selective identity verification for certain Claude users in April 2026, requiring a government-issued physical photo ID and live selfie through third-party provider Persona to prevent abuse, enforce policies, and meet legal obligations. The rollout followed Anthropic’s report that Chinese AI labs allegedly used roughly 24,000 fraudulent accounts and more than 16 million Claude exchanges in large-scale model-distillation efforts, highlighting the limits of account-based controls against coordinated extraction networks. The post argues that KYC measures also support safeguards against dangerous model misuse and prepare frontier AI providers for growing regulatory expectations, while acknowledging privacy concerns about linking AI activity to verified identities and the risk that verification requirements could expand without clear limits. It situates Anthropic’s action within a broader trend in which major AI labs are tightening access controls and may adopt financial-sector-style customer verification, monitoring, sanctions screening, and re-verification practices, while advocating risk-based verification and transparent third-party data handling.
