How to do CPRM protection on SD

Hi, I was wondering how you can do this CPRM protection on a SD card. I bought an 8gb sd card that has this CPRM support, but I don’t know how to make my data protected from copying.
Does anyone know how I can find info on that?
Thank you very much,

I have another question, is there anyway other than CPRM to protect the data against protection on a SD card? For example, a SD card can only be read by a certain computer.
