Adding a Digital Signature to Sent Files

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. A system option is required in order to use this function (System Options). 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
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). 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
