Hi there,

 

I want to sell some college notes by putting them on CDs but I don't want the people that I sell them to, to be able to burn the CD and sell it on?

I'm wondering if there is a way to put my notes on a CD so that they cannot be copied directly?Just like the way that you can't burn DVDs that you buy in a shop?

I know that they could screenshot each page anyways but that takes a bit more time.

 

If anyone knows how this is done I would really appreciate it.

 

Thanks a million!

My first guess is that you would have to purchase a copyright-protection/anti-copying protection program that would do to your CDs and DVDs what businesses have had done to theirs -- render the material very difficult if not impossible to copy.

Thank you very much for the reply!

Can these be bought in a normal computer shop or are they only online?

Dunno, never bought such; however, call a couple of computer stores, they can probably steer you in the right online or local direction.

in my opinion what you require is not possible, because it is a 2 step process and usually requires the encryption key to be stored in the hardware/players firmware plus the encryption of the disk itself to stop just anyone making copies and playing them on any other device.

 

yes you can easily encrypt the data and then burn it to the cd but then you have to give the key to the person who buys the cd, so they can unencrypt the data and read it, so after that the buyer has everything they need anyway to easily make copies.

 

and just for info yes it is possible to copy and burn a store bought dvd to disk if you know how.

Not every DVD can be copied; many have increasingly better anti-copying whatevers built in.
