ZeroVu Signature: The digital signature that protects your documents
Sign your PDFs with complete confidentiality. Your document never leaves your device. Only a SHA-512 cryptographic hash is transmitted. Adobe AATL certified, legally valid.
Traditional solutions expose your documents. ZeroVu Signature changes the game.
Traditional signing platforms require your files to be transmitted and stored on their servers. Contracts, amounts, confidential clauses... everything is readable by a third party.
With Quebec's Law 25, organizations are responsible for data entrusted to third parties. ZeroVu Signature eliminates this risk: your PDF never leaves your device. Only a SHA-512 cryptographic hash is transmitted.
ZeroVu = Zero visibility for third parties. That's our commitment.
The ZeroVu Approach
Your PDF document stays on your device. Only a SHA-512 cryptographic hash is transmitted. Content invisible, inaccessible, never stored.
Everything happens locally, in your browser
Your PDF stays with you
The document is never transmitted to our servers. ZeroVu processes it entirely in your browser.
Only the SHA-512 hash travels
A unique cryptographic hash is generated and transmitted. The document content remains completely invisible.
The signer applies their signature
Invitation by email or SMS. The signer signs securely, protected by a verification code.
Validated by Adobe AATL
The signed document is verifiable directly in Adobe Reader through our certification on the Adobe trust list.
