DRM methods

I would like to learn something about methods of rights management in
CAD documents in PRO-E and possibly other CAD systems.

What type of data is exchanged? What file types?
Is the access to the files coupled with a certain viewer?
Are the files digitally encrypted?
Is there a decryption/certificate exchange process involved?
Is there a notification process (email) about who is accessing the
information involved/possible?

Where can I read on about this technology?

 

Thanks. I visited the links below.

Any other products?
I read also about a product named "Trustview" and found an article (in
german) in the peridoical "Digital Engineering":
http://www.em.ag/Downloads/Referenzen/Presse/DigitalEngineering_emAG.pdf

What I'm especially interested in is the question whether there are
digital signing methods are involved and whether model files can be
included into this DRM procedures. Would that require some kind of
Viewer if not the full CAD system at the clients site?

 

That's a joke, isn't it ?
The white paper I got is in german, too. Nice would be if the video
presentation could be listened in german also.

I must admit hadn't studied the white paper throuroughly enough when
posting my previous question. I think
at this point in time I have gathered enough information to get a
picture of what's involved with the PTC DRM solution.

Thanks a lot.

What exactly did you refer to with "cutting edge question"? And what
issue?

are even aware of this issue. If you are authoring software or
designs, it's an immediate issue. But let's be honest: DRM is
confronted by a million trained code crackers. Whatever it is,
technically, do you think it stands a chance? However, even evaluating
its abilities is way beyond mine (and probably the scope of this
newsgroup).

Thanks a lot so far for answering my questions.

The technique/technology of Digital Rights Management is supposed to answer the question, posed for decades, of how can CAD authors protect their investment, their intellectual property. Various questions have been raised in this forum which partially or indirectly addressed this question. But no solution was available. Simply brining up an available technique in this forum for addressing the issues of CAD authors protecting their investment, DRM as a solution and how much this can accomplish with regard to "keeping secrets" was a unique and valuable contribution. It has not been discussed here before. So, thank you for introducing the subject.
