Secure PDF

• Secure PDF module allow you to upload a PDF to your course, and prevent students from downloading it.


• Students will get an image of each page and not the PDF itself.


• The images are protected from "right click" to prevent saving the image.


• Module completion will be set only while user saw all pages of document.


• You must know that people with web development skills will be able to download the images (one by one)
