Electronic signatures and electronic seals can both help protect the integrity of electronic documents, but they serve different purposes.

An electronic signature is associated with a signatory, while an electronic seal is used by an organization to help guarantee the origin and integrity of documents it issues.

Electronic signature verification analyzes several elements that help establish the trust status of a signed or sealed document.

Signature Checker checks:

• whether an electronic signature or seal is present;
• whether the signature or seal is valid;
• whether the associated certificate can be trusted;
• the available validation information.

No. A valid electronic signature or seal can confirm elements related to the integrity of a document, but it does not prove that the document's content itself is authentic, accurate or fraud-free.

To analyze the document's content, detect fraud signals and identify inconsistencies, additional document verification such as Document Trust is required.
