Cryptographic provenance for important communications
We Secure Data can create provenance evidence for messages and documents, helping prove who sent them, when they were sent, and whether the content has changed.
Secure delivery needs more than access logs.
Provenance is cryptographic evidence about where a document came from, who sent it, and whether it has changed. Conventional file sharing usually depends on account access, timestamps, and platform logs. Those are useful, but they do not give a recipient independent proof that a file is genuine.
We Secure Data signs critical documents and verifies their integrity so recipients can check sender identity, origin, and tamper status without relying on third-party document trust prompts.
Document created or sent
A critical document is prepared for secure exchange.
Hash generated
A unique digest is created from the document contents.
Cryptographic signature applied
The digest is signed to bind origin and integrity to the file.
Recipient verifies author, origin, and tamper status
The recipient can independently confirm whether the document is genuine and unchanged.
Audit-ready evidence for trusted delivery.
Proof of origin
Origin is proven cryptographically, not inferred from a platform screen.
Proof of sender
Important documents can carry evidence about the sender identity behind the delivery.
Proof of integrity
Recipients can verify that a document has not changed since it was signed or delivered.
Tamper detection
If a signed document changes, verification can show that integrity has failed.
Offline verification capability
Documents can be checked independently when access to the original system is unavailable.
Audit-ready records
Provenance records support legal, financial, medical, government, and board workflows where trust needs evidence.
