CD-Protect works on the principle of direct hardware coding on the CD-ROM. While trying to read a CD master treated as described, unreadable sectors are reported. These areas cannot be copied to the hard drive without further ado due to the operating system (Windows 9x/Me/2000/XP). The attempt to read the CD with a copying software is either directly terminated or takes up to several hours. Copying to a blank CD is thus hardly possible with the copy protection.


Hardware-/ software-based copy protection:

Additionally, the source code can be delivered in the programming language C. This code enables to simply check the copy protection. This is based on the InstallShield Professional and can just be integrated into the setup. The direct integration into the software is possible as well though. If the copy protection cannot be found on the CD, running the setup or the software will be cancelled.
