Hi, Walter.
The NR3 files are standard PDF files, in the sense that they completely follow the specifications set by Adobe. However, the Adobe specifications allow for the possibility that the content of the PDF file is stored in an encrypted form, and that the decryption algorithm is in a plug-in. The specific plug-in that we use, the FileOpen plug-in, verifies that your specific machine (as defined by hardware configuration and stored subscription information) is authorized on a specific subscription. If it is authorized, it decrypts the file (all within Adobe Reader). If not, not. So your statement that anyone with the plug-in can read the file is not correct -- they also have to be subscribers.
There is no such thing as perfect security, and we are certainly not attempting that -- there are at least several holes in the above security model. But, for now, it seems good enough to allow an acceptable business model and let us offer NR3 online. If the FileOpen security model ever got seriously broken, we would probably have to remove NR3 from the web, which would be too bad for legitimate users (and for us!).
Cheers,
Bill P.

Pdf Drm Removal Tool

In most cases Windows users can remove the FileOpen.api by launching Control Panel and Add/Remove Programs (on Vista/Win7, Programs and Features) right-clicking the entry for 'FileOpen Plug-in for Adobe Acrobat and Reader' and selecting Uninstall. Used to be able to remove the FileOpen Security. Because of lawsuites, etc they removed this functionality in version 1.33, or Version 1.01 for professional edition. FileOpen is unusual if not unique in having created a DRM solution according to these rules. And the benefits are important for developers. The services exposed by FileOpen enable full control over users/documents/policies via high-level interfaces (REST, SOAP) that can be fully integrated into other applications or portals in either an on.
