PDF Security and Copy Protection.

Secure PDF : Copy Protecting PDF Documents

The options included in most PDF creation include password protection, expiry protection and print protection. Unfortunately these security options can be exploited when using generic PDF readers. To appreciate the extent of this weakness one only has to perform a web search "protect PDF" to see numerous PDF protection apps, most of which are useless because they can be decompiled using free software to extract all content including text and images.

Password Protection

Password protection is only as secure as the reader used and there is free software available for extracting PDF passwords that works with most generic PDF. To properly protect PDF documents a "secure reader" is needed, one that has been specially designed resist all exploitation and hack methods.

Expiry Protection

Setting an expiry date on a PDF document is a common practice but it is easily exploited by setting back the computer's date to rejuvenate an expired document. To properly secure PDF expiration, the reader should refer to an online timer server.

Print Protection

Limiting the number of prints cannot be maintained without logging usage and the most secure method for logging is by using an DRM database online. Any reader trying to police its own security as a standalone application will be keeping its records on the user's computer and thus be exposed to exploit.

Prevent Forwarding

There is nothing that can prevent one from sending a file to others, but it is possible to restrict the use of that file. To properly prevent forwarding DRM can be applied to documents to control access to the document's contents, ie: without approval from the author the document cannot be opened.

Copy Protection

Preventing a document's contents from being copied is a most difficult task because while a document is open its contents can be copied by many techniques including copy-and-paste, using Print Screen or screen capture software.
