What is the main purpose of signature verification in DocuSign?

The main purpose of signature verification in DocuSign is to ensure the signer's identity and document integrity. This process is crucial in digital transactions, as it confirms that the person signing the document is indeed who they claim to be and that the document has not been altered since it was signed. Signature verification employs various methods, including the use of cryptographic techniques and secure authentication processes, to provide a robust layer of security that enhances trust in electronic signatures.

When a document is signed, the signature creates a unique digital fingerprint that is tied to the signer's identity and the document's content at the time of signing. If any changes are made to the document after it has been signed, the signature will become invalid, signaling a potential security issue. This ensures that both the authenticity of the signer and the integrity of the content are maintained throughout the document's lifecycle.

The other options, while relevant to document management, do not capture the essential role of signature verification in ensuring a secure and legitimate signing process. For example, verifying document completion dates, tracking edits, or generating encryption keys serves different purposes that are not centered on confirming identity and ensuring document integrity.
