TL;DR: Digital transactions need more than convenience: certificate-based digital signatures and identity verification reduce fraud, preserve integrity, and support legally recognised trust in regulated workflows, according to GlobalSign. The governance issue is that electronic speed does not remove the need for strong identity assurance, tamper evidence, and accountable issuance.

Editorial analysis by NHI Mgmt Group, based on content published by GlobalSign: “El importante papel de la identidad digital en la firma de documentos”.

Key questions

Q: How should teams choose the right signature assurance level for regulated workflows?

A: Match signature assurance to the transaction’s legal, financial, and audit consequences.

Q: Why do basic electronic signatures create more risk in regulated document workflows?

A: Basic electronic signatures reduce friction, but they do not provide the same cryptographic assurance as certificate-based signatures.

Q: What breaks when digital signature certificates are managed with weak identity controls?

A: Weak controls undermine both trust and usability.

Practitioner guidance

  • Define signature assurance tiers by transaction risk Classify workflows by regulatory impact, dispute likelihood, and evidentiary need, then map each class to the minimum acceptable signature assurance level.
  • Require certificate-backed identity proofing Use certificate issuance only where the signer has been verified to a level that matches the transaction’s legal and operational consequences.
  • Separate basic e-signatures from regulated approvals Reserve lower-assurance signatures for low-risk workflows and keep regulated approvals bound to PKI-backed signatures with revocation and validation controls.

Bottom line: Digital signatures only solve the regulated transaction problem when identity assurance and document integrity are both enforced.

Signature issuance is an identity governance event, not a formatting choice. The article is right to treat digital signatures as a control over who can bind themselves to a regulated transaction. In practice, the real governance question is whether the signer’s identity was verified strongly enough for the document’s legal and operational consequences. Practitioners should stop treating signature tools as a pure productivity layer and evaluate them as part of the identity assurance stack.

A question worth separating out:

Q: What is the difference between a trusted digital signature and a basic electronic signature?

A: A trusted digital signature is tied to certificate-based identity verification and cryptographic integrity, so the signer and document can be validated after issuance. A basic electronic signature is usually just a workflow acknowledgement or image of approval, which is easier to use but much weaker as legal evidence.
