CD Problem

[Mero]

Hi All
I want to protect a cd from being copied so check the logical serial number with GetVolumInformation (.....) function but this serial is still the same when coping this cd with CD Copy option so any idea that makes this CD unique ????

Thank u all

It is very difficult to assign a copy restriction directly to a digital source. There are some methods that write to CD sectors that are difficult to write to with standard CD burners and yet are easily readable by the same equipment, to store rights information there. Copies, then, are less likely to be able to completely duplicate the original disc. However, as CD burning technologies have advanced, these methods have become increasingly difficult to perform, since more and more burners are able to access more and more sectors (due to market demand for larger CD storage sizes).

A more reasonable rights management model is to tie the software to a particular user or machine (or both) through encryption and installatation keys generated from passwords, hardware reads, and even remote internet verifications.
