Feature · Integrity
Proof that a document has not changed.
Every file receives a SHA-256 fingerprint on upload. You can prove at any time that the document is identical to the one that was uploaded, down to the second.

Sealed in the audit log

Any change would produce a different fingerprint.
How it works
The fingerprint is generated without you thinking about it.
The moment your client or a member of your team uploads a file, Meo computes its SHA-256 fingerprint and records it in the audit log. Any later change would produce a different fingerprint, detectable immediately.
- SHA-256 computed automatically on every upload
- Fingerprint kept in the audit log, attached to the file
- Verification available at any time, exportable if the document is challenged
