5. Usage Notes

• Verification is performed locally in the browser: structure, base64url decoding, JSON parsing, signature match and time window (iat/exp).
• Signature check uses the same local key string as the issuing tool. Both pages must use the same key to be consistent.
• No data is transmitted to any server by this page. It can be used on isolated devices or internal networks.

This verifier does not generate or alter biometric signals. It validates Anti-Deepfake session tokens produced by the Encounter Liveness & Optical HR module. All processing runs locally in the browser. No video, audio, or logs are automatically transmitted to any cloud service by this page.

Optical HR values contained in the tokens originate from a non-medical optical estimation and are not certified vital-sign measurements. They must not be used alone for clinical diagnosis, emergency decision-making, or therapy planning. Use them only as auxiliary information and always within your organization’s security, data-protection, and clinical governance frameworks.
