The definition of Copy Protection Software is too often
used inapporpriately, especially in the case of file protection
applications. The term "copy protection" means prevention
of copy as in the case of an image that is displayed in a viewer
and the user is prevented from making a copy of that display.
In an instance where protection from making a copy of file is
sought, then you are really taking about the prevention of file
duplication or write prevention in the case of copying
a file to a removable disk.
If this definition is still not clear because you think that by
sending a file that you are sending a copy, let's look at it another
way. You might have software that encrypts files and protects
them by requiring a password or other special condition before
displaying its contents. When that file is open, are you prevented
from printing or taking a screen shot of its contents? If the
answer is "no" then that application is NOT for copy
protection at all.
So why then do so many software vendors claim that their products
are for copy protection? The answer in most cases will
be because they are intentionally falsely advertising a weak product
that would otherwise be of no interest. Most are merely clones
and the developers so lame that even their documentation and keywords
are borrowed from their role models. If you use Google for a web
search on "copy protection" you will see in the right
hand column to a list of Adwords scammers who pay for keywords
that are not applicable to their product at all. For example WatchDox
is incapable of copy protecting anything, NewSoftwares apps only
lock files and LockLizard's claim to provide software for secure
mail is a blatant lie.
The rest might be capable of providing password, print and expiry
protection, but as already mentioned these features do not copy
protect a file's contents when open and they should be re-classified
as being for file protection. Only then will the people
looking for copy protection be able to find apps that do just
that, and only then will those that do provide real copy protection
software be able to trade clear of the pollution created by
scam artists.
If you are looking for file protection software then you
won't have any trouble finding hundreds of applications, most of
which will be based on elementary encryption resources that are
free Windows resources. These apps are commonly promoted as using
strong encryption and it's not uncommon to see the same application
rebranded and offered from lots of different domains using different
company names.
So what sort of software do you really need?
