Yii2 How to output a protected pdf document?

Question

JavaScript

Hello. How can I display a protected document on the site? The site is made on yii2. Of course, you can give a direct link to a protected pdf, but the joke is that firefox does not care that it is protected and you can copy text through it and print it out. xD
It is better to put the question this way: how to display and protect a PDF document on the site from text copying, printing, opening in a new window. No frames. You can stupidly so that there was a scroll well, or even a scale. Everything.

Answer 1

forgot to include js scrollspy plugin

Answer 2

Why only firefox? In any browser, you can press the right key, download and unlock. Or use a different from the standard pdf viewer, which can ignore. So I think you are Don Quixote.
