Hi :)
So you want something like "Captcha" as found in many websites but
want it for normal documents?  I'm not sure how to do that at all.
Hopefully someone else might.  My 4 thoughts would be;

1.  Could the documents be stored on an intranet?  Errr, i mean on a
website that can only be accessed from inside the university
buildings?  (maybe also by people who are allowed access from outside)

2.  my other thought is to have a website that people have to login
to.  Perhaps different areas within the website so 1 area for physics,
one for engineering, another for arts.  Each area could have a
different group of users with their own individual passwords.

3.  Some sort of Cloud arrangement for sharing files where individual
files can only be accessed by specific people people invited to look
at a certain file?

4.  Have you heard of "moodle"?  Maybe something that already exists
might be able to do what you want already.

As i said i hope someone else has a better idea

Tom :)

Hi again :)
errr, i should point out that this is a public-access mailing-list so
there are people here from all over the place, many different
skill-sets, many different ways of approaching problems.  The
flip-side of that is that it's best to avoid sending confidential
information to this mailing-list so attachments don't reach the list
at all to avoid potential embarrassment.

Hi :)
I have no idea what exactly the question is here.

If you are looking for help on how to crack into a system then this
probably isn't the place.  We might be able to point you towards some
tools but we don't have much experience doing that sort of thing.
Also we can advise on password generators or places to store them (or
places NOT to store them and passwords to avoid!).

I tend to find that files that are password-protected in MS Office are
easy to open in LibreOffice.  Just open as normal.  But that is more
to do with MS's apparent refusal to take security serious and just
talk about it all the time and invent new words for the various
different vulnerabilities they seem to like writing into their

So, please just reword the question or say it a different way or try
to give more of an idea of what you are trying to do so that we can
have a better attempt at trying to help.
Regards from
Tom :)
