Crypto界网消息，Anthropic has launched an identity verification mechanism in some use cases of Claude to prevent abuse, enforce usage policies, and fulfill legal obligations. The process is supported by Persona, and users are required to submit government-issued photo ID and may undergo real-time selfie verification. Anthropic states that verification data is only used to confirm identity, not for model training, nor for marketing or advertising. If verification fails, users can retry multiple times within the process or submit a form for manual assistance. Accounts may be banned if they repeatedly violate usage policies, terms of service, register from unsupported regions, or are used by individuals under 18.
