Digital signatures are used for integrity of the signed media and authentication of the signers in digital environment. Beyond these the signature might provide an authorization service for a verifier to check whether the signer has license to sign the document in workflow. This verification is important in case of exchanging valuable documents between different organizational levels and also crucial in digital document archive.
