This article provides an overview of digital signature technology, and how Vinesign uses this technology to ensure your documents are secure.
Digital Signatures and PKI
Digital signature technology allows a document to be locked after all signatures have been collected, providing an additional layer of security. Digital signatures follow a set of requirements known as Public Key Infrastructure (PKI). PKI uses encryption to protect customers’ data and ensure that signed documents are valid.
The Role of HSM in PKI
The hardware security module (HSM) is a secure network computer that allows the PKI processes to remain secure. The HSM verifies documents by locking a document once it has been signed. In the case of multi-sign documents in Vinesign, the HSM verifies each signature individually as they are collected. Documents that have already been signed cannot be re-uploaded as a new document in Vinesign for validation purposes. Additionally, once all signatures have been completed, documents cannot be edited or re-sent, as they are locked once fully signed.
View Signature Validation
To view a signed document’s signature validation, open the document PDF in Adobe Reader. Click the left side bar to expand the panel, and then click the pen icon. Adobe will show you if the document is signed and all signatures are valid.
