Not really. If you want to track access Adobe sells tools that will do that, but they are not cheap.
thank you for your help, I have another question. Lets say I create my pdf using JS (i.e. the pdf is originaly blank), if a person disabled JS the pdf would remain blank? Is this correct?
I would have a go at it myself but I wanted to make sure it is possible before I go and spend vast amounts of money.
Are we talking about Reader users or Acrobat users? I think everything is available to Acrobat users unless you used DRM or password security. Password security is easily circumvented, DRM is not, but again DRM is not cheap. How important is it that you block access to a pdf file.
This would be for reader users.
It is essential that I can block a user from viewing a pdf file if certain conditions are not satisfied.
What options would I have?
