SAP Adobeform manipulation

How to make the generated SAP Adobeform safe from the editing(Not by setting password-this is already done). The downloaded form should not be editable using any third party tool. Can anyone suggest how to do it.

Regarding your comment. You are describing a scenario where you initially protect the pdf via login credentials, but after downloading it, this protection no longer applies. Regarding raw pdfs on a clients harddrive see my initial answer.

I already mentioned multiple ways to circumvent manipulation.

Hi Gagan,
you are essentially trying to solve three goals here:
1. Make the pdf viewable
2. Make it available offline
3. Automatically prevent any tempering with the pdf

Unfortunately these goals conflict with each other. As soon as you are able to see the document you could theoretically make a screenshot, edit the document in an image manipulator editor and create a new pdf. Also the pdf specification is open source, so if adobe acrobat checks for a flag and disables pdf editing, another editor can simply ignore this flag and still show/edit the full pdf.

What do we offer:
- Password protection: makes it more complicated to view the pdf, but the file is now encrypted (temper protection + integrity protection)

- Certificate signing: pdf is still readable, the authenticity is confirmed, tempering cannot be prevented but you will see if the pdf was edited

General:

I am not aware of any DRM method available on the market that fulfills all goals. Often we have either a closed system and encrypted data (e.g. game consoles), some DRM that rely on internet based decryption (eBooks). Or a combination of both. All these options are not viable for a media that is used for archiving.

Best regards

Hi Pascal,

I am making the adobeform to directly download into the system without the print-preview option. And moreover the user need to provide his login Id and password before downloading the form. After all this the client wants- the downloaded form should not be electronically manipulated by any third party tools. Is it possible to achive?
