Yes. By not embedding normal PDF on the web page and instead using
PDF security software
to securely encrypt your PDF documents, even if your PDF is located, it will
not be of any use without the proprietary viewer to decrypt them and if
domain lock is used then the only way that anyone can view the document will
be from your web page. Today there is only one PDF security solution that
can display PDF on web pages securely due to modern web browser limitations.
Other solutions have to resort to using JavaScript which, while it may be
supported across all browsers and computer operating systems, cannot do much
beyond making it awkward to right click and save or print. Otherwise,
anything protected by JavaScript will not be protected at al.
Yes. There are some CD protection solutions that provide a layer
of security in the format of the disk itself, whether it is on
CD, DVD or USB drive. The more secure of these solutions provide
specially prepared media (disks) and special software for disk
production. The method employed by these solutions obscures the
content by storing key information in segments on the disk that
are not usually interpreted by disk copying software. When
techniques like these are used for popular media such as music or
movie files, then software will surely be published to get
around even this most clever protection technique. Using a low
profile solution may survive longer.
But as usual, once a file on a protected disk has been opened in
its viewing application or native program, then its contents can
still be used without permission, unless copy protection is employed for the file
itself.
Also, once the file is opened, it may be possible to copy the
file to another location (off the protected disk) for
redistribution by sending onward to other people. The only way
to prevent redistribution of files in this sense is to use a DRM
(digital
rights management) solution. When this happens, even if they can get a
copy of the file, sending it others will be futile because the next
person will not be able to access it.
Copy protection, like any form of security or measure taken to
prevent theft or unauthorized use, can never be 100% secure.
Some may say, "In that case, why bother?" and others hope that
nothing was in their way to do whatever they want with the
intellectual property of others and your livelihood.
But why make is it easy for them? There is a lot that we can do
and most security measures that we can employ on the Internet
will protect your property from most Internet users (+92%). Very
few, even those who may have the skills and know how, will want
to go to great lengths to get around your security and if done
carefully, your security measures can be so difficult to get
around that the effort required will not be profitable for them
and they will lose interest.
