-

hi everyone! brand new adobe community i've used acrobat years.

 

here's question/problem:

 

i wrote book investing can distribute in hard copy because of problems plagiarism, overseas.

 

i'd sell book pdf again need:

 

1) airtight, unique passwords each user

 

2) kind of watermark appears when printed copy made.

 

please help! serve market has lot of competition , many of them unscrupulous; paying members have informed me of rampant plagiarism , need make hard on bad guys possible.

 

thanks feedback...

 

keep stepping,

 

kurt

1) no such thing. every system based on passwords vulnerable brute force attack. consider drm, if budget in tens of thousands of dollars p.a.
