A digital signature is an electronic signature with the added advantage of digital authentication technology. Put simply, digital signatures provide the evidence of origin, identity, and status of electronic transactions and documents. They provide a layer of validation and security making them more difficult to forge than a handwritten signature.
Digital signatures ensure end-to-end message integrity, prove the identity of the organization that created the digital signature, and confirm that the information originated from the signer and was not altered. If any change was made to the signed documents, it would invalidate the whole transaction.
In many regions, including the U.S., EU, and APAC, digital signatures are considered legally binding and hold the same value as traditionally signed documents.
