Sign Private Document
Sign documents securely, knowing Ignisign does not access their content
Generate easily signature proofs on your infrastructure

Full Privacy documents are a solution to sign documents that you want to share only to the signers.

IgniSign does not store the document on its platform, and the document is not shared with IgniSign.
This mechanism is very useful when you want to sign a document that contains sensitive information.

You can only sign a Full Privacy document in Embedded integration mode.

How it works:

  • You create a Signature Request with a Full Privacy document and you provide only the Hash (SHA-256) of the document.
  • When you launch the signature session with the IgniSign JS SDK, the library ask to you to provide an URL where the document is located.
  • IgniSign retrieve the document on the frontend side and check the hash of the document with the hash provided in the signature request.
  • The document is not sent to IgniSign servers, and the document is never stored on IgniSign platform. The document is only kept in the browser memory, into the signer device.
  • If the hash of the document provided match the one provided during the signature request creation, The document is displayed to the signer and the signature session can start.

Signature Session in full privacy mode

  • Prerequirement : You need to have created a Signature Request with a Full Privacy document. An Example is available into the examples implementation Here

  • You need to have all elements required to launch a signature session with the IgniSign JS SDK. An Example is available into the examples implementation Here

Hereunder a diagram that describe the signature session in full privacy mode.

Generation of the signature proof in full privacy mode

Due to the fact that the document is not stored on IgniSign platform, The Signature Proof Document with full content of the documentcould not be generated by the IgniSign SaaS platform


We know that this form of signature proof is very appreciated by our customers, so we decide to provide a micro-service that is able easily process this kind of signature proof for you.
This micro-service need to be installed into your infrastructure. It is packaged into a Docker image that you can be easily installed into your system
This micro-service is certified by a Tiers party to ensure that your document is never transmitted to IgniSign platform.
