Prove who sent it. Prove it has not changed.
WSData can attach cryptographic provenance to critical documents so authenticity can be independently verified, even offline.
Normal file sharing proves delivery. It rarely proves origin.
Provenance is cryptographic evidence about where a document came from 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 mathematical proof that a file is genuine.
WSData signs critical documents and verifies their integrity so recipients can check author, 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.
Authenticity that can be mathematically verified.
Mathematical proof of authenticity
Origin and integrity are proven cryptographically, not inferred from a platform screen.
Offline verification
Documents can be checked independently when access to the original system is unavailable.
No reliance on third-party prompts
Verification does not need to depend on external document trust prompts.
Tampering becomes detectable
If a signed document changes, verification can show that integrity has failed.
Built for high-value documents
Useful for legal, financial, medical, government, and board documents where trust needs evidence.
