The Trade Compliance Records document verification engine uses SHA-256 cryptographic hashing to verify the authenticity and integrity of trade compliance documents. Upload any compliance certificate, regulatory declaration, or trade document to generate a cryptographic hash that can be independently verified at any time. The verification engine detects document tampering, confirms authenticity against the TCR compliance ledger, and generates immutable verification certificates suitable for regulatory submissions, legal proceedings, and audit trails. The system is compliant with eIDAS electronic signature standards and supports all major document formats including PDF, DOCX, and XML.
