Because the document needs to be edited by the purchaser, it makes security
very difficult. But assuming that the perpetrators are simply duplicating
the original CD, you could have a hidden code embedded on each disk. Keep a
record code and purchasers. When someone advertises them on eBay, buy a copy
and then you will find out who is guilty of the duplication. Sue them for
loss of sales and damages.
