Verify document authenticity with Claude and record proofs on blockchain

How It Works This workflow automates document authenticity verification by combining AI-based content analysis with immutable blockchain records. It is built for compliance teams, legal departments, supply chain managers, and regulators who need tamper-proof validation and auditable proof. The solution addresses the challenge of detecting forged or altered documents while producing verifiable evidence that meets legal and regulatory standards. Documents are submitted via webhook and processed through PDF content extraction. Anthropic’s Claude analyzes the content for authenticity signals such as inconsistencies, anomalies, and formatting issues, returning structured authenticity scores. Verified documents trigger blockchain record creation and publication to a distributed ledger, with cryptographic proofs shared automatically with carriers and regulators through HTTP APIs.
