My client has a program with rather sensitive information on it. He would
like it if the program installed on a computer be unable to be copied to
another computer. Failing that, he would like the copied program on the
other computer to fail to work without registration. That way he could know
that another copy was around somewhere.
So what is the best way to do this? I can think of putting files into the
preferences file on a Mac, but what would I do with Windows? Or is there a
better way?
For example, I have seen the functions "queryRegistry" and "setRegistry",
but I have no idea how these work or what I should do in order to be safe.
I also note that there are such features as platform(), machine(),
processor() and systemVersion(). A combination of these might work
partially, but not completely.
So I need some advice? Help, anyone?
No, he is not paranoid. There is just a very limited market. If the software
is freely able to be copied, then he loses his investment.
Thanks
Raymond
