Initiating Course with a code
For the e-learning courses that i deliver on a CD/DVD.. I want to implement a system that the user can start the course only after entering a certain code at the first/starting slide.. I can put a question slide for 'fill in the blanks' for that.. the Table of contents will be there on the side but I want the user should be able to proceed only after entering the right CD Code.. This is an effort to prevent piracy of the course, since as you know today we don't have anything very effective to prevent piracy from hard copies.. so at least a specific code authentication can make the course usable only for the specific user.. Can you please guide me with this.. ?
