Generating a Device Signature Key 

You can generate a device signature key and certificate that show a document was scanned on the machine. The certificate is appended when an original is scanned and converted into a PDF file.
A device signature key is generated only once, and cannot be deleted.
An optional Send PDF Security Feature Set is required.
The device signature key and certificate are valid for five years. Renew them when required.
