ProofDeed

0 reviews

ProofDeed is a Trust Infrastructure Platform giving any document independent, verifiable proof it hasn't been altered since creation or signing. When certified, ProofDeed generates a unique cryptographic fingerprint of the document and anchors it to an independent, public verification network no single party controls. ProofDeed never sees or stores the document itself, only the fingerprint crosses the boundary, so files stay entirely within the customer's own systems. Any court, auditor, regulator, or counterparty can later recompute the fingerprint from their own copy and compare it to the original. A match proves the document unaltered; a mismatch shows exactly when it changed. The verifier never needs to trust ProofDeed, only the math. Integrates via a single API call, no workflow change, no data migration. Legally defensible under U.S. Federal Rule of Evidence 901. Used by government, enterprise, and asset-heavy organizations for document, asset, and relationship verification.
