PDF Security :
Copy Protecting PDF Documents
PDF is a commonly-used document format because most computers will have Adobe
Reader installed. PDF readers are generally
free software so publishing
a document in PDF is a common practice for all sorts of tasks
like invoicing, proposals and user-guides.
The options included in most PDF creation include password
protection, expiry protection and print protection. Unfortunately these measures can be circumvented when publishing
generic PDF that can be read in any PDF reader. One only has to do a search on the Internet for "protect PDF" to see numerous PDF protection products,
most of which can easily be decompiled using free software to
extract passwords and content including images, text and other
PDF Password Protection
Any protection is only as secure as the reader used and there is free software available for extracting PDF passwords
that works with most "protect pdf" solutions. To properly
protect PDF documents one needs to encrypt and secure the
documents for display in a "secure reader", one that has been
specially designed for the task and especially designed to
PDF Expiry Protection
Setting a date on a PDF document for the document to expire is
a common practice but it is easy to exploit because one only has
to set the computer's date back in time to rejuvenate an expired
document. To properly protect PDF expiration, an independent
time check is required by consulting a timer server that is online.
PDF Print Protection
Print protection can only be secured and controlled by using a custom reader. Limiting the number of prints cannot be maintained
without logging usage and the most secure method for logging is
by utilizing an online database which is one of the principles
of DRM. Any reader trying to police its own security as a standalone application
will be keeping its records on the user's computer where it can be hacked.
Prevent PDF Forwarding
There is nothing that can prevent anyone from sending a copy of
a file to others, but it is possible to restrict the use of that
document by all recipients.
To properly prevent forwarding DRM can be applied to the
document to control access to the document's contents, ie:
without permission from the author the document cannot be
PDF Copy Protection
Preventing a PDF document's contents from being copied is a most difficult task. The PDF
file can be duplicated in its original form but the prevention of
the copy of its contents is something else because while a
document is open its contents can be copied by many techniques
including copy-and-paste, using Print Screen or screen capture
