I've done some research and found out that I can protect flattened PDF against editing (by Acrobat for example). The encryption will be implemented using Adobe LiveCycle Workbench Service Password Encrypt PDF.
I'd like to know if there is better or another way to lock PDF Editing for example using Rights Management, and what is the difference.
Also, if you could point me to sample code/process where I can perform such process using Workbench Service Password Encrypt PDF or Rights Management.
Current Situation: The current process will convert the filled XDP Form to a flattened PDF, and after that, we want to ensure that the user cannot use Acrobat to modify the PDF.
Appreciate your help.
