Adding a Device Signature
Convert the scanned original into a PDF file with a device signature. The device signature serves the same purpose as
sealing or signing a document; it can be used to check where the file was created and whether the document has been
tampered with or falsified after the signature was appended. To assign the device signature to a PDF file, you need to
generate the key and certificate for the device signature in advance. Generating a Device Signature Key(P. 415)
