Digital signature
A digital signature is a cryptographic method intended to verify the authenticity and integrity of a digital message or document. A valid digital signature indicates with a high degree of confidence that the message or document has not been corrupted or forged: it was created or sent by a known party and was not changed by a third party after signing, or otherwise tampered with.

In business automation
A digital signature confirms that a document came from a known party and was not changed after signing. In automation, it appears in agreements, customer approvals, and file transfers between systems, not as decoration on a PDF.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Approving a service agreement
A customer signs an agreement through a secure link. Only after the signature is verified does the automation open a case in the system and send a copy. A document without a valid signature remains pending and is not treated as consent.
