Imagine that your user prints the screen and then goes through an OCR software to recognize text.

Bad approach. You won't be able to avoid that.

You can't. Once you have presented the page to their browser, the user can do what they want with it. No matter what you do to try and stop them, there's always a way around it.

I suspect this is not the answer you wanted, but anything else is a lie.

Have a look:
You can use `user-select` CSS3 propertie

HTML like this :

HTML

<span class="protected">Datas you wants protect</span>

And the correspondant CSS :

CSS

.protected {
        -moz-user-select:none;
        -webkit-user-select:none;
        user-select:none;
    }

See an example : http://jsfiddle.net/DoubleYo/RPv4q/[^]

This solution is not cross browser but work fine with firefox and chrome/safari

Advanced user can copy your content with view the page source, make pdf or print your page, and some people mention firebug, fiddler.
