Topic: PDF to TIFF then back to PDF

Hi,

We need to publish some PDF documents that have to be modified. The problem is that the information that was on the original unmodified PDF is not to be accessed by anyone, once the PDF has been modified.
My understanding from other topic conversations is that a PDF is never completely secure, even with protection settings activated.

We are looking for an inexpensive solution.

I think I found the solution, but I need someone to confirm if this would work.
First I would use the rectangle drawing tool to hide the information.
I would save the pdf as a .TIFF. This would create many documents. One per page.
Then I would open the TIFF documents that were produced by combining them in one PDF document.

I believe that the information that was on the original PDF would not be recoverable in this second PDF since it has been produced from a TIFF document ? Am I right ?

Thanks for your help.
