Adding Copy Protection

Tuesday May 28th 2002 by Vinoj Kumar

A scheme for programmatically adding and using copy protection to disks you distribute.

Environment: Visual C++

This copy protection scheme first requires you to detect bad sectors in the floppy disks. Then, four of the bad sectors are selected. Pressing the copy protect button will write a secret data file to the floppy disk that is the key disk. Then, to use the copy-protected floppy disk, you have to call the DLL file which reads the secret area and determines if it is the copy-protected key floppy disk. The DLL can be called anywhere in your program. You can even call it from Visual Basic.
