Don’t let anyone steal your book.
When I first got into E Book Publishing I had a problem with people repackaging my E Book and reselling it. I had to find some software that allowed me to lock the E Book they downloaded to just one computer. That way someone can’t buy one copy and share it with all their friends and rob me of profits. I also need a way to deactivate the access even on the computer where it was bought if the customer wants a refund. There is software that will address these and many other security and profit stealing challenges. I like to think I have the best.
