Real Human Verification (RHV): A Hardware-Rooted Cryptographic Standard for Human-Origin Visual Evidence

This document defines Real Human Verification (RHV), a public cryptographic standard for establishing a constitutional root of trust for direct human-origin visual evidence in the post-AI era. RHV specifies cryptographic primitives, hardware-backed capture requirements, and public transparency logging mechanisms that allow digital photos and videos to prove that they originate from a physically authenticated human capture pipeline. RHV does not judge content truth; it defines cryptographically verifiable human-origin capture, tamper-evident integrity, and publicly auditable provenance chains. By anchoring visual evidence in hardware roots of trust and append-only transparency logs, RHV provides a neutral, publicly verifiable foundation for judicial, institutional, and societal reliance on digital visual evidence across operating systems, cameras, drones, and sensor-based capture devices.
