WrittenInStone proves file integrity without exposing contents. Instead of storing files, we generate a cryptographic fingerprint (hash) and keep it in a lightweight registry. Anyone can later verify that a received file matches the original—quickly, privately, and across tools.
In a world of AI-generated content and rising transparency demands, trust requires provenance. WIS ensures files aren’t silently altered between creation, handoff, or audit.
Creators and studios proving originality. Journalists and investigators handling sensitive media. Compliance, legal, and audit teams needing repeatable verification.
Integrity proof (hash-only): confirm files remain unchanged. Receiver-side checks: verify directly in browser or CLI. Audit-friendly exports: CSV/PDF hash reports. Zero disruption: we never store or modify your files.
Trusted timestamps for version history. C2PA/Content Credentials support. Provenance manifests with optional metadata. Similarity detection for images, text, and audio.
Ensuring a unified and unique identifier for each digital asset to maintain consistency and traceability.
