Protecting a PowerPoint Presentation

[Kathy]

Is there any means to "copyright" or protect a presentation? We want
to share a presentation with others, but don't want them taking credit
for it or making changes to it. Can anyone help me?

By creating it, you've pretty much established copyright. In other words, it's
yours and if you catch somebody stealing it, you can make a couple lawyers and,
with a little luck, yourself some money on the deal.

Mac PowerPoint and Windows PPT prior to 2002 don't support password protection.
You might consider converting the PPT to PDF instead. You can password
protect PDFs so that people can open but not print or change or copy from them.

Like all copy protection schemes, PDF's is imperfect; it can be cracked, but
it'll keep the average user out.

I guess what I'm asking, is there anyway to "embed" a logo
or watermark in each slide that cannot be removed?

 

[TAJ Simmons]

I guess you could put a logo or semi transparent graphic on the "slide master"....then export "File > Save As...>file
type JPG".....everyslide as a JPG....but then it's not a powerpoint presentation, and you would lose all the
effects/animations if there are any.

or watermark in each slide that cannot be removed?

You could convert all the graphics on the slide master(s) to a single bitmap
image and include your watermark in that. To remove the watermark, they'd
either have to remove the image altogether or laboriously edit it.

There are other invisible ways of marking the presentation that could be used
later to establish that the presentation's yours.

Google "Digimarc" or "Digimark" (not sure of spelling) for an invisible way of
watermarking images.

Using VBA, you can tag any slide or shape in the presentation with any
information you like.

Sub Example()
With ActivePresentation.Slides(1)
Call .Tags.Add("Copyright", "Me, 2004. Hands OFF!")
End With
End Sub

That tacks some invisible information onto Slide 1 in the current presentation.

You can also give shapes unique names. Every rectangle in the presentation
will normally have a name like "Rectangle 1" If you gave a certain rectangle
on each slide a name like "Rectangle 42" (when there are only 2 rectangles on
the page so PPT never would have created that number on its own) it'd be
another way of identifying the slide as yours. Or just name the shape
"MINE!ALL MINE!" <g>
