I have seen some of these products.  I believe Adobe will do this as
well.  I have not however, rant into a software package that can prevent
screen shots from being taken.

Today at the Cebit I saw a product by a company called airzip called
document secure that let's you contol the access rights on a document
level. You can allow a person to only view a document. The person then
will not be possible to print it or save it somewhere if you don't allow
it. The product basically creates a wrapper around the doc that stores
this info. If you have extremly sensitive information you might use a
tool like this to prevent this documents to be walked out of your
systems on disk, USB sticks or paper.

There's not much that you can practically do here, I think.

The problem is that although there are many good technical and 
procedural methods of ensuring that only authorised people have access

to your systems - and therefore your information - there are few 
technical or procedural things you can (realistically) do to control 
what those authorised people do with the information they have access 
to.

Content security systems (like Mimesweeper) can check outbound emails,

and block anything that contains project codenames. But that won't 
stop someone printing it out and putting the paper in their briefcase.

Because this is such a low-tech crime, you're left with policy and 
procedure as your only tools.

You should consider making it policy that information does not leave 
your sites, without written permission from a senior person. This will

cause trouble for those that telework, however. You could also brief 
security staff on what to look for - keep them appraised of new 
storage media (like those nifty USB pen drives), and give them the 
authority to do random stop and search jobs.

Make sure that all emails and documents have - by policy - a 
boilerplate on them saying who owns that intellectual property. Tacky,

but it might be useful in a court of law - and it reminds employees of

the stark reality.

All of these safeguards (except boilerplating, which could be enforced

via templates etc.) are the sort of things people get complacent on 
very quickly, because they stand in the way of people working. Within 
six months of implementing them, senior people will be signing off 
that John Smith can take home "anything relating to projects X, Y and 
Z" simply because they don't want to sign it off three times - even 
though John Smith doesn't actually work on Y and Z.

So really, the only defence against this is contractual. All employees

must sign an NDA, stating that they will not divulge proprietary 
intellectual property. Make them sign it, and understand why they are 
signing it. Don't make it too draconian - you don't need the ability 
to search their home, for instance. (That's what law enforcement 
agencies are for.) But you should make it clear that if they steal, 
they'll be sued. Having to spend that pay rise you got when switching 
jobs on legal fees is not an attractive proposition.


Finally, it should be pointed out that many companies won't actually 
accept stolen IP, because it's a legal minefield. But NDA's make it 
difficult for both the person acting as a conduit as well as the 
ultimate recipient, and may make employees who were only casually 
thinking about it think twice.

Nothing, however, will stop the determined person who's miffed at the 
company and leaving for a competitor. Nothing except the competitor's 
honesty and their own legal team's advice, anyway. :-)
