Adding a Digital Signature to Sent Files
4XR3-0EH
By adding a digital signature to a scanned document that is sent in a particular file format, you can certify that the
document has not been altered and is guaranteed by the creator. The machine can add a device signature or user
signature to documents.
Device Signature
The device signature uses a key and certificate mechanism, enabling the recipient
of a scanned document to verify that it was created on this machine. The
recipient can check what machine was used to create the document, as well as
whether the document has been altered. Before you can add a device signature,
the key and certificate (device certificate) used for the device signature needs to
be created on the machine. Generating a Device Signature
Certificate(P. 779)
User Signature
The user signature is linked with personal authentication management functions,
enabling the recipient of a scanned document to verify who created it. As with
the device signature, the user signature enables the recipient to check whether
the document was altered after the signature was added. A system option is
required in order to use this function ( System Options(P. 1481) ). Before you
can add a user signature, a key and certificate (user certificate) needs to be
registered for each user via the Remote UI. Registering a User Signature
Certificate(P. 780)
●
For information on validating certificates, registering certificates in the trusted certificates list, and verifying
signatures on the reader side, see the documentation for the software that supports the PDF format (such
as Adobe Reader/Adobe Acrobat).
●
You can set multiple digital signatures for a file. In this case, device signatures are applied before user
signatures.
●
If a recipient verifies a PDF or XPS that has had multiple signatures added to it using software that supports
the PDF format (such as Adobe Reader/Adobe Acrobat) or the XPS format (such as XPS Viewer), only the last
signature added to the file remains valid. The device signature causes the document to be handled as if it
has been altered.
●
You cannot forward a received I-fax document with a user signature from the machine.
TIPS
Displaying a digital signature (visible signature)
Digital signature information can be displayed on the first page of the document, making it easy for the reader
to see that a digital signature has been added. Only PDF documents support visible signatures. Adding a
