I am doing some volunteer work with a small charity, and they are creating a CD with PDF and JPG's on, and they will be selling these to help fund some of the charity.
They would like to where possible make these harder to copy, but still easy for a buyer to use. Obviously as a charity it needs to be very cheap / free, and fairly easy to produce, not mega volumes, but maybe 5 at a time.
I found something called SecurDisc, but it can only copy protect a pdf, and only does it on a DVD, and these needs to be a CD.
Any suggestions would be much appreciated.
