Solution 3

no way to stop copy if viewer is any computer technical

but for normal user you can add attribute on body tag of your html page
i.e.

HTML

<body oncontextmenu="return false;" onselectstart="return false;" onkeydown="return false;">
</body>

and many more if it works

How about providing information on how to do it with JavaScript. Link to an article would have been very helpful.
