Anyone can create an electronic signature file and use it to sign email messages, documents and other data types. However, the security level on this kind of signature is often negligible because it is easy to change and alter. There is no real way to authenticate an e-signature as being a valid signature, especially when it has been attached to legally binding documents, purchase orders, purchase requisitions or other financially important papers.
An Electronic Signature Can Be Converted into a Digital Signature
You can change an electronic signature into a digital signature in order to make the signature more secure. A digital signature does allow you the ability to authenticate the signature as being real, since this type of signature is encrypted anytime it is attached to a document, form or file. Once converted, users will need to have their own signature certificate in order to have the ability to securely attach their signature.
