Here I am sharing you a code snippet which you can use to protect your specific page to be copied. This Code will disable Right Click, CTRL+C and CTRL+V etc. I got this code from StackOverflow.com and modified it a little so that you can use it for your WordPress Page.
Just change the Page ID in the code with your own page ID which you want to be protected.
<?php
if(is_page('YOUR PAGE ID')){?>
<script>
jQuery(document).ready(function() {
jQuery(function() {
jQuery(this).bind("contextmenu", function(e) {
e.preventDefault();
});
});
});
// Disable Right click
document.addEventListener('contextmenu', event => event.preventDefault());
// Disable key down
document.onkeydown = disableSelectCopy;
// Disable mouse down
document.onmousedown = dMDown;
// Disable click
document.onclick = dOClick;
function dMDown(e) { return false; }
function dOClick() { return true; }
function disableSelectCopy(e) {
// current pressed key
var pressedKey = String.fromCharCode(e.keyCode).toLowerCase();
if ((e.ctrlKey && (pressedKey == "c" || pressedKey == "x" || pressedKey == "v" || pressedKey == "a" || pressedKey == "u")) || e.keyCode == 123) {
return false;
}
}
</script>
<?php } ?>
