It depends what data it is. Star Force afaik is only for executables.

Normal data can simply be copied.

You would have to have a reader application on the CD, and only that reader can read the data. Depends if you want to go that far.

What kind of data is it ? Documents ?

Bottom line - you can't make it copy proof you can only make it difficult to copy.

>> yes data is PDF and Documents,

That's what I was afraid of. Unless you encrypt the data, and find some way to make the data readable ONLY with your application on YOUR cd, then they can simply copy the data, no matter what you do.

So, two things to do :

1) an application that can only run on your cd : that can be achieved with protections like StarForce (as pointed out by Tolomir)

2) encrypt data so they're only readable with your application : that's harder, since your application will somehow have to contain the decryption key, so you'll need to hide it in there pretty well to avoid that people extract it from the executable.


Be aware that none of these are 100% solutions !! A determined person that wants to copy the data will be able to do so.
Furthermore, be aware that this is a very cumbersome way of doing things, and your customers might not be very happy about it. Imo, you need to have a very good reason for this.

Since there were no further questions from nnnddd, I assume that his question was answered. Imo all participating experts made valid helpful comments, and a PAQ would allow others to see them.

CD is not a reliable media to lock your PDFs to.

It's better to look for solutions which can protect and lock down the PDF contents of your CD to users specific computers.
