I am creating a website in which customers can create their own documents. I have created templates in InDesign and the customer can adjust the texts in the website.
What I would like to see, is the option to encrypt a PDF, so that the customer cannot save this PDF-file to his computer. Is there any way in which I can encrypt the View preset, so the customer can NOT save this document? I know that there is no Security-tab in the InDesign-PDF preset, but is there any other way?
I don't want the customers to see a LoRes-PDF on the website, nor do I want to place a watermark over the documents (I don't think this looks pretty).
Thank you in advance for your answer!
