What ensures the integrity of a signed document in DocuSign?

Digital certificates and secure encryption play a crucial role in ensuring the integrity of a signed document in DocuSign. When a document is signed electronically, it is accompanied by a digital certificate that verifies the identity of the signer. This certificate acts as a safeguard, indicating that the signature is authentic and has not been altered since the signing occurred.

In addition to digital certificates, secure encryption is utilized to protect the document's content, making it unreadable to unauthorized parties. This security measure prevents tampering or unauthorized access, ensuring that the document remains unchanged from the moment it is signed. Together, these technologies create a secure environment in which the integrity of the signed document is maintained, giving confidence to all parties involved in the transaction.

Other options, such as requiring physical signatures, regular backups, or printing on high-quality paper, do not provide the same level of security and verification that digital certificates and encryption offer in the context of electronic signatures. Physical signatures can be forged, backups alone do not prevent tampering, and printing does not ensure the document's integrity. Hence, the combination of digital certificates and secure encryption is the most effective means of protecting electronic documents in DocuSign.
