Human Provenance Standard — HPS

Human Provenance Standard (HPS) establishes verifiable provenance records for digital documents and creations. Key features include: • Cryptographic verification of asset integrity • Dual signing by creators/institutions and the HPS registry • Identity assurance from self-declared to institutional levels • Management of supporting evidence and attestations • Record status tracking for active, disputed, or revoked claims HPS provides a robust framework for documenting the origin, ownership, and integrity of digital content. It moves beyond traditional reliance on logos or signatures by creating a verifiable chain of trust. Creators can sign their own declarations, while authorized institutions can issue signed records. The HPS registry then verifies and countersigns these records, ensuring a clear separation between claimed contributions and verified facts. This system is built on a layered trust stack, incorporating SHA-256 for asset integrity, Ed25519 for creator and registry signatures, and mechanisms for independent attestations and evidence sealing. It empowers users to demonstrate and verify the genuine human contribution behind digital works, crucial in an environment where content origins can be ambiguous. Ideal for organizations, creators, and institutions that need to establish and maintain transparent, accountable, and verifiable records of digital ownership and creation. It serves anyone requiring robust documentation of provenance for intellectual property, research, or content publishing.
