INSAXO WrittenInStone creates tamper-evident proof records for digital files. We generate a cryptographic fingerprint (hash) and timestamp it in an immutable registry — so anyone can verify integrity later without seeing the original content.

Why it matters: Files get copied, edited, and re-shared. With AI in the mix, it’s harder to prove what was original and whether anything changed after handoff.

Who it’s for: Creators and studios protecting originality and deliverables. Journalists and investigators working with sensitive materials. Compliance, legal, and audit teams that need repeatable verification.

What you get today: Hash-only proof records (default) to detect any change. Instant verification in seconds. Audit-ready exports: evidence logs and reports for reviews and disputes.

Roadmap: Versioned timestamps, content credentials (C2PA), provenance manifests with optional metadata, and similarity checks for text, images, and audio.
