This piqued my curiosity- So I created a "locked" PDF from InDesign,
with a password required to copy, edit, select etc text and changes.
Opening it up in Preview, the security settings are respected. You can
select text with the text tool, but can't copy to the clipboard without
the password- same with images. The print dialog box has "save to
pdf.." grayed out as well.
Again, someone who really wanted to could probably crack it, but it
seems to hold up under 'normal' use.
You might also have luck with PDFPenPro from smileonmymac.com, which
while still pretty pricey, is less than the Adobe stuff.

Doesn't the "host" app that is displaying the PDF have to "obey" these
settings? What I mean is that if it is still unencrypted text,
couldn't it easily be extracted? These security settings seem like
ways to keep the "regular" people from getting at the data, but it
seems like it wouldn't take too much work to get at it.
So if you take this document and print it to PDF, will the new PDF
obey these settings? If not, then you just quickly converted it into
an unsecured PDF.. perhaps I'm missing something.

Well PDF was created by Adobe. You might consdier looking over
their web site <http://www.adobe.com>. I have never heard of a
"secured" or "locked" version of PDF, but I've never looked either.

With the full version of Acrobat you can set the security settings to
allow or prevent certain things like copy/paste, exporting,
printing, opening etc. It's under Document Settings->Security.
