Adding a Device Signature
Convert the scanned original into a PDF le with a de
vice signature. The device signature serves the same purpose as
sealing or signing a document; it can be used to check where the le was created and whether the document has been
tampered with or falsied after the signature was appended. To assign the device signature to a PDF le, you need to
generate the key and certicate for the device signature in advance.
