protection

[kvol]

-- Hi,

I'd like to sell powerpointpresentations using a webshop. What would be
the best protection against unauthorised copying ?
Protection programs exists for windows users, but I can't find a program
that works for MAc users. Can anyone help me in this issue ?
Are there already webshops where you can download -after payment -
powerpoints ?

Hi

Anyone who thinks that there is an effective way to use technology to stop
copying is only kidding themselves. Screen recording programs and video
cameras make copying a cinch. Why bother?

What protects you is copyright law. The fact that it is easy to make copies
doesn't make it legal to do so. Learn your rights and contact an attorney if
you think someone has violated your rights:
http://en.wikipedia.org/wiki/Copyright_law

Any kind of digital rights management scheme is risky for the copyright
holder. What happens if your method of stopping copying infringes on someone
else's right to copy your work? Teachers have the right to make copies of
your stuff and use otherwise copyrighted materials in their face to face
classrooms in many cases. There may be other exceptions to your copy rights.
You could face claims that you are denying legitimate rights to copy your
stuff if you don't handle your DRM correctly.
http://en.wikipedia.org/wiki/Fair_use

There's nothing to stop you from reminding folks of your digital rights.
Hopefully, if you decide to use this method, that you don't go overboard
with ridiculous statements about the FBI and sweeping untrue statements
assertions about copyright that you see when you pop a movie into your DVD
drive. The copyright law is plenty strong without misrepresenting it.

thanks Jim,

I agree with you, but what about an effective protection against editing a
powerpoint ?

Distribute PDF instead?

Hi,

As Steve suggests, you can throw obstacles in their way. You can save it as
PDF (you lose all animations, transitions, movies and sounds), use File >
Make Movie (and put it into iDVD and make it a disc image), convert it to
Adobe SWF with impatica, or do one of many other strategies.

But if someone really wants to put it back into PowerPoint then it's
relatively easy. QuickTime lets you save individual frames of a movie,
screen grabs are easy.

I don't think there is an effective way to protect against editing a
PowerPoint except to never let anyone see it. People could even re-create
your presentation from memory after they've watched it.

To make matters worse, if they change it enough in the process of
re-creating it, it's possible that they could have created a new work that's
different enough to be granted a new copyright and they don't have to give
you a plug nickel.
