    Copyrights Security Digital Watermarking


      Hello, I'm a Internet Tax Attorney Speaker. I create my own books for my classes,  at the bottom I state that my books have Larry Stein Copyrights 20XX.. I email my books scanned in a regular pdf format. I have encountered people who are printing and using my books more than once and using my the information in a unauthorized manner. I wanted to know what can I do to keep track of my books.. to know who opens the files and how many time.. if I can put a restrictions on how many time they can open the file.. and know that they can just be stealing my information... I'm new to my CS3 so I was hoping someone can guide me in the right direction.
