To prevent divulging of information from a sent file

You can restrict file viewing with a password or assign operation privileges to a file when distributing original data as a PDF file. Also, you can add a digital signature using the certificate of the MFP. Encrypting a file prevents unauthorized viewing by third parties. Furthermore, adding a digital signature provides assurance regarding the authenticity of a file author (MFP) and ensures that the file has not been falsified.
