Best way to create/protect PDF crossword?

hello,

 

i've created giant crossword puzzle i'd players pay for, download , fill out either on- or offline.

1) create pdf of puzzle highlights squares , corresponding clues;

 

2) inform player when puzzle completed;

 

3) add security measures, keep purchased puzzle being duplicated , forwarded other players?

 

thanks help!
