Digital Trust API - Infrastructure for Verifiable Data Provenance & Integrity.

The Empe Trust API is managed infrastructure designed to secure the data supply chain via cryptographic attestations. Treating data integrity as the primary asset, it abstracts W3C Verifiable Credentials to allow enterprises to issue and verify tamper-proof data packets—from KYC results to IoT sensor readings. This ensures critical data carries its own mathematical proof of origin, independent of the transport layer or storage medium. Key Capabilities: - Cryptographic Data Signing: Transforms raw JSON payloads into cryptographically sealed attestations. The service manages signing keys and DID bindings, ensuring every data point is tamper-evident and non-repudiable. This prevents data injection attacks and guarantees integrity in transit. - Attestation Lifecycle Management (Issuer): Governs the full data lifecycle, supporting dynamic streams and high-availability revocation. Issuers can instantly invalidate outdated or erroneous attestations, ensuring downstream consumers act only on current, trusted information. - Provenance & Integrity Verification (Verifier): Validates the source and content of incoming data without shared secrets. It cryptographically verifies data origin and integrity, facilitating private, off-chain exchange where the data itself serves as the verifiable source of truth.
