QuotePM me if you want some more info about it..   That's what I've been doing for the last 10 years. (IBM mainframe software development for PDF creation/conversion/security/content extraction)
You be smart ... ;D

There is not a PDF file I have recieved that I cannot alter its content -- with either Word or WordPerfect. Some I can open up and alter with PDF Creator. This really worries me as 100% of my billings and renewal contracts are done in a PDF file format. The only saving grace there is if it is one is the creation date of a modified PDF file will be differant that the original. Then again I'm sure somewhere there is a hack to get around that.

Originally I'm sure PDF files were very safe, but today with all of the bells and whistles I believe there are as many holes in it as that are in a sponge.

If you know of something more secure in a PDF format and if it does not cost me an arm and leg PLEASE let me know.

Thanks,

Olds, I will let you know.    I've just run across a PDF that is locked down pretty d@mn tight, and doesn't use any external CRM DRM gee-whiz stuff...   My go-to 'cracker' software won't have anything to do with it, other than attempt brute-force attacks to get the Master password.

I'm tearing it apart now by other means..

I won't bore everyone with the details, and I will send you a dreaded PM when I find out more.
(due to the nature of the software I'm using to do this, I'd rather not announce to the general public what I am trying)

I use Adobe Acrobat 8, and can produce some very secure documents. A PDF file created with Acrobat is as secure as the author wants to make it. I'm not saying they can't be unlocked, but you can make it pretty damn hard for the every day end user.

If a document is easy to copy, or export to a word processor, the document's security is minimal. To find out what the author allows you to do with the document; open a PDF file and right click on it. Click on "Document Properties." While in "Document Properties" click the "Security" tab; that will show the "Security Method" and list the "Document Restrictions Summary" status.

This particular file was locked down in all aspects, *except* Content Copying for Accessibility..

I was never able to unlock the file to modify it's contents, but I used a slightly modified PDF text extraction library to mimic a screen reader, and pull the contents into a text file (and extract any embedded images).

Habs is right.  Built-in PDF security will keep out the average Joe.
