How to protect my CD from Copying

Only thing you can really do is password protect the data. Assuming you aren't going to try to sell the CD or anything, putting the data in a passworded ZIP file will keep most people from getting at the data(which makes copying worthless); but since that isn't uncrackable, there's no 100% garunteed way to copy protect a CD.
 
There are a few freeware CD Copy protection utilities out there that can add some basic software copy protection to tge CD but I've never found them to be particularly good as most of them can be easily bypassed if one is determined enough to do so.
You might want to check out CD Media World, there may well be someting there to assist you.
 
Passwording or encrypting the data wont do any good, the person making the copy will just unencrypt/unzip the files or just write the key on the copy
 
If you can record a CD with your recorder, someone else can read it and then re-record it in another recorder.
There is nothing that you can do about that.

Commercial CD copy protection works by using specially modified master 'recorders', which are able to write CDs that most recorders cannot record.

Your only option is encryption, or a similar procedure. As to how you protect data from being copied after decryption - that probably a very hard task as well.
 
There are a few programs that make copy protection but clonecd can crack it. The only one was CD protector 4 but you can't find it anymore and it's also only a beta version.

well, if-you-h@ve-your-key-like-this-no-one-would-cr@ck-it (with a normal PC)
Download PGP encryption software and try it
 
Yeah, but if the guy copies the disc he can scripple down the key for each dupe 🙂
The only *REAL* way is to write an online ASP.
ie, create your own file format to store the data, and make your viewing application internet enabled where it can not operate without a connection to your server (Some necessary functions can be performed by the server, as well transferring necessary parts of the ASP program to the client). Then pull a Windows Product Activation kinda scheme and store the data on your server so it can't be circumvented without you providing the exception. But I can pretty much guess that this is outta reach for you (And me).
 
Oh, and I think we're all a little confused here: Copy protection is a *BAD* thing. We should all be allowed our legal backups. It should be illegal to copy-protect anything beyond the reasonable ASP/WPA methods (Those still allow working backups). It really should be.
