I want to create a pdf file with non-copyable properties for text.
It can encrypt text to some code (such as ASCII), deny copy paragraph.
I found some examples on web about this. I must use font 13pt with Times New Roman for my thesis, so I use package extbook, type1cm, mathptmx. When I use these pacakges, I can't encrypt my text to deny copy.
Please help me solve this problem.
I see you marked this question already answered. I know this answer but it can't solve my problem. I must use extbook and some more package. And this answer not working. Please see my code:
\documentclass[13pt]{extbook}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage[utf8]{vietnam}
\usepackage{type1cm}
\usepackage{mathptmx}
\usepackage{setspace}

\usepackage[dayofweek]{datetime}
\usepackage[pdftex,bookmarks=true,bookmarksnumbered,hidelinks]{hyperref}
