There are several products around that promise to protect content from being copied, like http://www.antssoft.com/htmlprotector/ for example. I know that these techniques are not foolproof, but I would still like to implement them on a CMS that I am developing.
Rather than buy such a product however - which may well have practical or licence limitations - I would prefer to implement such copy protection directly. How do I do that though? There seems to be more than JS involved.
Pretty much everything that products like HTMLprotector can do!
I am particularly interested in preventing text copy from the browser, and also in HTML encryption techniques which still enable the text to be readable in the browser.
I know that practically any copy-protection scheme can be 'hacked', but even so some security measures would be useful.
You can also encode your html so its not immediately readable by humans - but what's the point? Its only html and its not like you'll have come up with some amazingly original code that you dont want people to see. If people are interested enough in your code they'll work through the encoding.
Your best bet to protect your text is to put it in flash, an image or if a downloadable pdf...
