How to protect physically manufactured, silver pressed CD from copying

[paul1979]

Hi

Just wanna ask you of how to protect physically manufactured, silver pressed CD from illegal copying.

It is not a mystery that lots of physically released material is lacking good selling because of pirate copying and sharing the audio for free. Free downloads made from physical copies can kill the potential profits from selling the media so I am curious if there's any real chance to stop that, making silver CDs impossible to copy for a home-made software such as Nero etc.

Any ideas?

With a ratio like yours you should be uploading your silvers

I use a wall safe that requires my fingerprint and the physical key to open.

I don't know of any consumer software that is capable of this. I have a couple discs that I've never been able to copy (Residents' pReserved Mole box is one). But if someone really wants to, they can do an analog rip of a CD just like you would with an LP or a cassette. Not the most ideal method, but where there's a will, there's a way.

Physical media sales are very weak, the last few albums I've bought were digital copies (FLAC) from sites like bandcamp.

Not a fcuking chance. As others said, if there's a need there's a solution and any measure leads to countermeasure.

Saying that, I'm still buying physical media - CDs, DVDs and Blu-rays for my quite a big collection.

Good god, why does someone want to do this now? LOL
Doesn't anyone remember how Sony CD's for a while had rootkit spyware on CD's to try and prevent copies? What a stupid idea it turned out to be! It messed up people's computers back then!

There's tons of ways they tried, but in the long run it's pointless.

What are you trying to do anyway? And, why???

He wants to sell his stuff and doesn't want people to be able to copy it and trade/sell it after they buy his stuff? Maybe it offends him when people freely distribute the work of others that he might be trying to profit from?

No.

Anyone interested in protecting their own disks should not be particularly concerned. Copy protection, in general, does not work. If you have a self-written application, such as a toy or a CAD package, you might be interested in one of the commercially licensed schemes, using an electronic dongle. In general, however, if the disk can be read, its contents can be copied. If you don't want your data to be copied by anyone, you'd better encrypt it.
A simple and common way is to increase the length of several files on a CD to make them appear to be hundreds of megabytes long. This is done by setting the file length in the disc image much longer than it actually is. The file is practically overlapping many other files. Since the program knows the actual file length, the software will work fine. If the user tries to copy the files to the hard disk, the attempt will fail because the CD supposedly contains several GB of data. (In practice, this does not stop anyone because they always make copies of the disk image. Furthermore, no standard software allows you to create such disks.)
