DRM methods

  I would like to learn something about methods of rights management in=20
  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?

As of Wildfire 4 & Windchill PDM/ProjectLink 9, PTC does DRM through an =
Adobe product that's built into the authoring software. The link below =
is a "What's New" precis on the addition of DRM to Pro/E and links to =
other resources.

The link below provides a way to get a white paper from PTC on their DRM

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?

You're welcome. So what did you think of the white paper on DRM? And the =
ohter stuff on the PTC website?


  Any other products?

  german) in the peridoical "Digital Engineering":

So, did you want us to translate the German for you?


  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.=20


The article talked about nothing BUT models. I don't understand your =
question/confusion. As to the technical details of how DRM is executed, =
I'm sure that it's a closely guarded secret about which, naturally, we =
know absolutely nothing.


  Would that require some kind of
  Viewer if not the full CAD system at the clients site?

I think this depends on your environment. If you're working within a =
PDMLink environment, you already have ProductView for viewing files =
(once unencrypted). You may also be part of a controlled releasing =
procedure where you have some kind of rights to annotate/comment on =
digital data. Outside of this environment, your end users would probably =
need Pro/e because the DRM is licensed to the authoring tool as a =
seperately purchased addon. But this kind of question is best answered =
by PTC and its sales staff. They'd LOVE for you to call them.

Thank you, though, for this cutting edge question. Not even one percent =
of Pro/e users (much less general computer users) 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).

BOL,

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

confronted by a million trained code crackers. Whatever it is,
technically, do you think it stands a chance? However, even evaluating

Thanks a lot so far for answering my questions.
