Enhancing the Security of Electronic Files
 | Digital files are vulnerable in terms of security because they can be easily viewed or tampered with leaving no trace. When scanning important documents, you can take appropriate measures such as encrypting data and adding a device signature to enhance security. |
 |
Encryption and device signature are only available for PDF files. Both the encryption and device signature can be used at the same time. |
Encrypting a PDF File
You can encrypt and send/save a PDF file by setting a password when scanning originals. The password setting helps reduce the risk of the PDF file being viewed or edited by others.

<Acrobat 7.0 or Later/128-bit AES>
Encrypt the file in the 128-bit environment, which can be opened by Adobe Acrobat 7.0 or later.
<Acrobat 10.0 or Equivalent/256-bit AES>
Encrypt the file in the 256-bit environment, which can be opened by Adobe Acrobat 10.0.
<Acrobat 10.0 or Equivalent/256-bit AES> can be changed to <Acrobat 9.0 or Equivalent/256-bit AES> with a different compatible version. <256-bit AES Set. (Encrypt. PDF)>

Enter the same password, and select <Apply>.
10
Select <Apply>.
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
