Is there anyway to protect PDF files from unlocking software?

by on October 24, 2010

Q: Is there a way to TOTALLY lock pdf files so that no one can use any of the freebie unlocking software out there to copy, print, right click, screen print, etc. to dup my materials?

    Nope, there isn’t any copy protection on the planet that is foolproof. If people can read your material, they can copy it.


      Thanks Mark. That was not the answer I wanted to see. I guess I will have to suck it up and deal with it and hope that my pics do not end up on the www being manufactured by the zillions of Chinese dress manufacturers. :((


    Your best avenue of protection is to consult with a copright/ patent lawyer to see what types of legal agreements and legal protections are available to you.

    As far as technical solutions go, if someone can read your pattern they can copy it somehow.


      Again, thank you very much for your replies and the link about IP rights in China. I do work part time for an IP firm here in the states and I know you pretty much have to go ahead and file lawsuits, and doing something like that from the states that involves a foreign country, foreign attorneys, is so costly that it really isn’t worth the time and effort unless you have money you can just burn or are a large enough that has money to fund lawsuits of that type. I see from the plethora of chinese websites that they download pics of dresses with the watermarks actual on the pics. It appears many companies do not have the funds to go after the piraters. I was so hoping that once you put a software lock on the pics of the pdf’s that they could not be copied. Again, thank you so much for your replies. I truly do appreciate your time. Thanks, Gin
