How to Tell If a Document Has Been Digitally Signedby Kayla Lowe
Digital signatures are used to authenticate digital information such as documents. They assure the viewer of the document that the information it contains is authentic and that the contents have not been modified since it was digitally signed. Such signatures also indicate the origin of the document. It's relatively simple to tell if a document has been digitally signed.
Open the document in question.
Locate the bar directly beneath the horizontal menu toolbar.
Look for a red medal or ribbonlike icon. This icon indicates that the document has been digitally signed.
- Another way to tell if a document is digitally signed is to try to make changes to it. Digitally signed documents won't allow changes.
