OriginLens is an evidence-first media provenance explorer built for transparent, client-side image inspection. 1. Cryptographic Validation: Parses and verifies C2PA credentials, digital signatures, and asset bindings directly in the browser. 2. Structured Evidence Ledger: Traces every finding to discrete checks, transparently distinguishing verified, unverified, and inconclusive signals. 3. Provenance Delta: Compares two images side-by-side across hashes, metadata, and normalized visual differences without inferring intent or truth. 4. Privacy by Design: Operates entirely in volatile local session memory with zero external relays, persistent caching, or server storage. 5. Objective Integrity: Replaces speculative "real vs. fake" scoring with auditable, standards-compliant provenance facts.
